Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 16/998,697 entitled "Fluid Transfer Devices
with Extended Length Catheters and Methods of Using the Same",
filed Aug. 20, 2020, which claims priority to U.S. Provisional
Patent Application Ser. No. 62/889,252 entitled "Fluid Transfer
Devices with Extended Length Catheters and Methods of Using the
Same" filed Aug. 20, 2019, the disclosures of each of which are
incorporated herein by reference in their entirety.
BACKGROUND
[0002] The embodiments described herein relate generally to fluid
transfer devices. More particularly, the embodiments described
herein relate to fluid transfer devices having a controlled size
and/or catheter length.
[0003] Many medical procedures and/or surgical interventions
include inserting an access device or fluid transfer device into a
portion of the body. For example, catheters and/or other
lumen-defining devices can be inserted into and/or through vascular
structures to access portions of the body. In some instances, such
catheters, access devices, and/or the like can have relatively long
catheter lengths, which can present challenges during use. For
example, in some instances, catheters and/or access devices used in
interventional cardiology can have a length of 300 centimeters (cm)
or more, which can result in the use of such devices being
cumbersome and/or difficult. In addition, the length of such
catheters and/or access devices can result in undesirable bending,
flexing, and/or kinking.
[0004] In other instances, catheters and/or other lumen-defining
devices can be used to transfer fluids from or to a patient. In
some instances, it may be desirable to maintain a relatively small
and/or compact form factor of such fluid transfer devices to
increase ease of use and/or decrease manufacturing and/or material
costs. In some such instances, however, maintaining a relatively
small and/or compact form factor can result in an undesirable
reduction in an effective length and/or "reach" of a catheter
included in the device.
[0005] By way of example, peripheral intravenous catheters or lines
(PIVs) can be inserted into a patient and used for infusing fluids
and medications. In general, PIVs are not designed for blood
extraction with failure rates that typically increase with
indwelling times (e.g., due to obstructions, build up, debris,
clots, fibrin, etc.). In some instances, however, a fluid transfer
device can be coupled to a proximal portion of a PIV (e.g., the
portion outside of the body) and can be used to advance a catheter
through the indwelling PIV to a position in which a distal end of
the catheter extends beyond a distal end of the indwelling PIV.
While such devices can position the distal end of the catheter in a
portion of the vein receiving a flow of blood that may otherwise be
obstructed or limited due to the presence of the indwelling PIV,
some such devices can have a relatively long length in order to
allow for the desired placement of the catheter beyond the PIV.
Moreover, the length of such devices can be further increased when
the devices are configured for use with extended-dwell or midline
PIVs, and/or peripherally inserted central catheters (PICCs).
[0006] Thus, a need exists for compact fluid transfer devices have
a controllable size and/or catheter length.
SUMMARY
[0007] Devices and methods for transferring fluid to or from a
patient through a placed peripheral intravenous catheter using a
relatively compact device are described herein. In some
embodiments, an apparatus includes a housing, a catheter, and an
actuator. The housing has a first port and a second port that is
coupleable to an indwelling vascular access device. The catheter
has a proximal end portion and a distal end portion, and it is at
least partially disposed in the housing such that the first port of
the housing receives the proximal end portion of the catheter. The
actuator is partially disposed in the housing to selectively engage
a portion of the catheter in the housing. The actuator is
configured to be rotated an angular distance relative to the
housing to move the distal end portion of the catheter a linear
distance from a first position in which the distal end portion of
the catheter is disposed in the housing, to a second position in
which the catheter extends through the second port such that the
distal end portion of the catheter is distal to the indwelling
vascular access device when the second port is coupled to the
indwelling vascular access device. The linear distance is greater
than the angular distance.

DETAILED DESCRIPTION
[0030] The embodiments described herein can be used in any suitable
medical procedure and/or surgical intervention. For example, in
some embodiments, a device such as those described herein can be
used as an access device or the like during surgical intervention.
In other embodiments, a device such as those described herein can
be used to transfer fluids between a patient and any external
connection, fluid source, fluid reservoir, etc. As one example, any
of the embodiments described herein can be used, for example, to
transfer fluids to or from a patient via an indwelling peripheral
intravenous line (PIV) (or other suitable access device or port).
In such embodiments, the device can be coupled to an indwelling or
placed PIV and can be manipulated to advance a catheter through the
PIV to position a distal end portion of the catheter beyond a
distal end of the PIV (e.g., within a target vein). In some
embodiments, the devices can have a relatively compact form factor
yet are arranged such that the compact form factor does not limit
and/or reduce a length, "reach," or "throw" of the catheter, as
described in further detail herein.
[0031] In some embodiments, an apparatus includes a housing, a
catheter, and an actuator. The housing has a first port and a
second port that is coupleable to an indwelling vascular access
device. The catheter has a proximal end portion and a distal end
portion, and it is at least partially disposed in the housing such
that the first port of the housing receives the proximal end
portion of the catheter. The actuator is partially disposed in the
housing to selectively engage a portion of the catheter in the
housing. The actuator is configured to be rotated an angular
distance relative to the housing to move the distal end portion of
the catheter a linear distance from a first position in which the
distal end portion of the catheter is disposed in the housing, to a
second position in which the catheter extends through the second
port such that the distal end portion of the catheter is distal to
the indwelling vascular access device when the second port is
coupled to the indwelling vascular access device. The linear
distance is greater than the angular distance.
[0032] In some embodiments, an apparatus includes a housing, a
catheter, and an actuator. The housing has a first port and a
second port that is coupleable to an indwelling vascular access
device. The catheter has a proximal end portion and a distal end
portion, and is at least partially disposed in the housing such
that the first port of the housing receives the proximal end
portion. The actuator defines and inner channel and is partially
disposed in the housing such that the actuator and the housing
collectively define an outer channel. The actuator is rotatable
relative to the housing to move the catheter between a first
position and a second position. The catheter in the first position
extends within the housing from the first port, through the outer
channel and the inner channel, and to the second port. The catheter
in the second position extends within the housing from the first
port, through the inner channel, and through the second port.
[0033] In some embodiments, an apparatus includes a catheter, a
housing, and an actuator. The catheter has a proximal end portion
and a distal end portion and defines a lumen extending through the
proximal end portion and the distal end portion. The housing is
configured to house at least a portion of the catheter. The housing
has a first port configured to receive the proximal end portion of
the catheter and a second port configured to couple the housing to
an indwelling vascular access device such as, for example, an
extended-dwell PIV and/or the like. The actuator is movably coupled
to the housing. A portion of the actuator is disposed within the
housing and is in contact with a portion of the catheter. The
actuator is configured to be rotated an angular distance to move a
distal end portion of the catheter a linear distance, where the
linear distance is greater than the angular distance. The distal
end portion of the catheter is disposed within the housing when in
the first position and extends through the second port when in the
second position such that the distal end portion of the catheter is
distal to the indwelling vascular access device.
[0034] In some embodiments, an apparatus includes a catheter, a
housing, and an actuator. The catheter has a proximal end portion
and a distal end portion and defines a lumen extending through the
proximal end portion and the distal end portion. The housing is
configured to house a spool mechanism and at least a portion of the
catheter. The housing has a first port configured to receive the
proximal end portion of the catheter and a second port configured
to couple the housing to an indwelling peripheral intravenous line.
The actuator is coupled to the housing such that a portion of the
actuator is disposed within the housing and in contact with the
catheter. The actuator is configured to be moved relative to the
housing to rotate the spool mechanism. The catheter is configured
to be moved, as a result of the rotation, between a first position,
in which the distal end portion of the catheter is disposed within
the housing, and a second position, in which the distal end portion
of the catheter extends through the second port such that the
distal end portion of the catheter is distal to the second
port.
[0035] In some embodiments, a fluid transfer device has a housing
with a first port and a second port, a catheter that has a proximal
end portion fixedly coupled to the first port, and an actuator that
selectively engages the catheter. In some implementations, a method
of using the fluid transfer device includes coupling the second
port of the fluid transfer device to an indwelling vascular access
device. The actuator is rotated an angular distance about a central
axis defined by the housing. In response to rotating the actuator,
a distal end portion of the catheter is advanced a linear distance
from a first position to a second position. The distal end portion
of the catheter is in the housing when the catheter is in the first
position, and is advanced linearly in a direction orthogonal to the
central axis through the second port and the indwelling vascular
access device as the catheter is moved to the second position. The
distal end portion of the catheter is distal to the indwelling
vascular access device when the catheter is in the second
position.
[0036] While at least some of the devices are described herein as
being used with and/or coupled to a PIV in order to transfer fluid
to or from a patient, it should be understood that such use is
presented by way of example only and not limitation. For example,
in other instances, the relatively compact arrangement of any of
the devices described herein can allow the devices to be used with
PIVs and/or other vascular access devices having an increased
length relative to the length of a standard or "short" PIV (e.g.,
extended-dwell PIVs, midline PIVs, peripherally inserted central
catheters (PICC), and/or the like), as described in further detail
herein.
[0037] While described herein as being used, for example, to
aspirate a volume of bodily fluid (e.g., blood) from a patient, it
should be understood that the embodiments and/or devices are not
limited thereto. For example, in some instances, the embodiments
and/or devices can be used to aspirate bodily fluid including but
not limited to, blood, cerebrospinal fluid, urine, bile, lymph,
saliva, synovial fluid, serous fluid, pleural fluid, amniotic
fluid, mucus, vitreous, air, and the like, or any combination
thereof. In other instances, the embodiments and/or devices can be
used to deliver one or more fluids from a fluid source to the
patient. In still other instances, the embodiments and/or devices
can be used in any suitable procedure or the like involving
catheterization of a target region in the body. That is to say, the
embodiments and/or devices are not limited to transferring fluids
to or from a patient and can be used, for example, to provide
access to a target region in the body of the patient for any
suitable purpose. Moreover, it should be understood that references
to "a patient" need not be limited to a human patient. For example,
any of the devices described herein can be used in any suitable
procedure performed on an animal (e.g., by a veterinarian and/or
the like).
[0038] As used in this specification, the singular forms "a," "an"
and "the" include plural referents unless the context clearly
dictates otherwise. Thus, for example, the term "a member" is
intended to mean a single member or a combination of members, "a
material" is intended to mean one or more materials, or a
combination thereof.
[0039] As used herein, the terms "catheter" and "cannula" are used
interchangeably to describe an element configured to define a
passageway for accessing a portion of the body (e.g., of a human
and/or animal). In some instances, the passageway defined by a
catheter and/or cannula can be used for moving a bodily fluid or
physical object (e.g., a stent, a punctate plug, a
hyaluronic-acid-gel, etc.) from a first location to a second
location. While cannulas can be configured to receive a trocar, a
guide wire, or an introducer to deliver the cannula to a volume
inside the body of a patient, the cannulas referred to herein need
not include or receive a trocar, guide wire, or introducer.
[0040] As used herein, the words "proximal" and "distal" refer to
the direction closer to and away from, respectively, a user who
would place the device into contact with a patient. Thus, for
example, the end of a device first touching the body of the patient
would be the distal end, while the opposite end of the device
(e.g., the end of the device being manipulated by the user) would
be the proximal end of the device.
[0041] As used herein, the terms "about" and "approximately," when
used in conjunction with values and/or ranges, generally refer to
those values and/or ranges near to a recited value and/or range. In
some instances, the terms "about" and "approximately" may mean
within .+-.10% of the recited value. The terms "about" and
"approximately" may be used interchangeably. By way of example,
about 0.5 would include 0.45 and 0.55, about 10 would include 9 to
11, approximately 1000 would include 900 to 1100, etc. Similarly,
the term "substantially" when used in conjunction with physical
and/or geometric feature(s), structure(s), characteristic(s),
relationship(s), etc. is intended to convey that the feature(s),
structure(s), characteristic(s), relationship(s), etc. so defined
is/are nominally the feature(s), structure(s), characteristic(s),
relationship(s), etc. As one example, a first quantity that is
described as being "substantially equal" to a second quantity is
intended to convey that, although equality may be desirable, some
variance can occur. Such variance can result from manufacturing
tolerances, limitations, approximations, and/or other practical
considerations.
[0042] The embodiments described herein and/or portions thereof can
be formed or constructed of one or more biocompatible materials. In
some embodiments, the biocompatible materials can be selected based
on one or more properties of the constituent material such as, for
example, stiffness, toughness, durometer, bioreactivity, etc.
Examples of suitable biocompatible materials include metals,
glasses, ceramics, or polymers. Examples of suitable metals include
pharmaceutical grade stainless steel, gold, titanium, nickel, iron,
platinum, tin, chromium, copper, and/or alloys thereof. A polymer
material may be biodegradable or non-biodegradable. Examples of
suitable biodegradable polymers include polylactides,
polyglycolides, polylactide-co-glycolides, polyanhydrides,
polyorthoesters, polyetheresters, polycaprolactones,
polyesteramides, poly(butyric acid), poly(valeric acid),
polyurethanes, biodegradable polyamides (nylons), and/or blends and
copolymers thereof. Examples of non-biodegradable polymers include
non-degradable polyamides (nylons), polyesters, polycarbonates,
polyacrylates, polymers of ethylene-vinyl acetates and other acyl
substituted cellulose acetates, non-degradable polyurethanes,
polystyrenes, polyvinyl chloride, polyvinyl fluoride, poly(vinyl
imidazole), chlorosulphonate polyolefins, polyethylene oxide,
and/or blends and copolymers thereof.
[0043] FIGS. 1 and 2 are schematic illustrations of a fluid
transfer device 100 in a first configuration and second
configuration, respectively, according to an embodiment. In some
embodiments, the fluid transfer device 100 (also referred to herein
as "device") can be configured to couple to and/or otherwise engage
an access device and/or the like and can be manipulated to place a
portion of a catheter in a desired position relative to the access
device and/or within the body. For example, the device 100 can be
coupled to an indwelling peripheral intravenous catheter (PIV) to
transfer bodily fluid from and/or transfer fluid to a portion of a
patient (e.g., aspirate a volume of blood or infuse a drug or
substance), as described in further detail herein.
[0044] The device 100 can be any suitable shape, size, and/or
configuration. As shown in FIG. 1, the device 100 includes at least
a housing 110, a catheter 130 (or cannula), and an actuator 150.
The housing 110 can be any suitable configuration. For example, in
some embodiments, the housing 110 can be an elongate member having
a substantially circular cross-sectional shape (e.g., cylindrical).
In other embodiments, the housing 110 can have a square,
rectangular, and/or any other polygonal cross-sectional shape. In
other embodiments, the housing 110 can be a cube or the like having
rounded or non-rounded edges, corners, etc. In still other
embodiments, the housing 110 can have any suitable irregular shape,
cross-section, and/or the like. In some embodiments, the shape of
the housing 110 and/or one or more features and/or surface finishes
of at least an outer surface of the housing 110 can be arranged to
increase the ergonomics of the device 100, which in some instances,
can allow a user to manipulate the device 100 with one hand (i.e.,
single-handed use). As described in further detail herein, the
arrangement of the device 100 is such that the housing 110 has a
relatively compact length or the like without limiting and/or
reducing a length of the catheter 130. In some implementations, the
housing 110 can have a length and/or size that is less than, for
example, a length of the catheter 130 at least partially disposed
therein.
[0045] The housing 110 has a first port 111 and a second port 112.
The first port 111 (e.g., a proximal port) is configured to receive
a proximal end portion 131 of the catheter 130 and the second port
(e.g., a distal port) is configured to movably receive a distal end
portion 132 of the catheter 130. The ports 111 and 112 can be any
suitable configuration. For example, in some embodiments, the first
port 111 can be a clamp, grommet, o-ring, compression member, Luer
Lok.TM., and/or any other suitable coupler. In some
implementations, the first port 111 can receive the proximal end
portion 131 of the catheter 130 and can allow a portion of the
catheter 130 to be disposed within the housing 110 while
maintaining a fixed portion (e.g., the proximal end portion 131) of
the catheter 130 outside of the housing 110, as described in
further detail herein. In some embodiments, the second port 112 can
be a lock mechanism and/or coupler configured to couple the housing
110 to a PIV (e.g., an indwelling or placed PIV) and/or any
suitable adapter coupled to a PIV (e.g., an IV extension set or the
like). For example, in some embodiments, the second port 112 can be
a Luer Lok.TM., a "Clip-Lock-Snap" connection, and/or the like
configured to physically and fluidically couple to, for example,
the PIV. Moreover, the second port 112 is configured to movably
receive the distal end portion 132 of the catheter 130 to allow the
distal end portion 132 of the catheter 130 to be advanced through
the second port 112 and the PIV (not shown in FIGS. 1 and 2) to be
at least partially disposed within a vein of a patient (e.g., the
vein in which the PIV is dwelling), as described in further detail
herein.
[0046] While the second port 112 is described as being configured
to couple to a PIV, it should be understood that the second port
112 can be configured to couple to any suitable connector, adapter,
access device, and/or any other suitable device. Moreover, as
described above, the PIV can be a standard or short PIV, an
extended-dwell PIV, a midline PIV, a PICC line, and/or the
like.
[0047] The catheter 130 includes the proximal end portion 131 and
the distal end portion 132 and defines a lumen (not shown) that
extends through the proximal end portion 131 and the distal end
portion 132. While described as defining a lumen, in some
embodiments, the catheter 130 can include and/or define multiple
lumens, channels, flow paths, etc. Although not shown in FIGS. 1
and 2, the proximal end portion 131 of the catheter 130 can include
and/or can be coupled to a coupler and/or lock configured to couple
(e.g., physically and fluidically) the catheter 130 to any suitable
device and/or reservoir (e.g., a syringe, fluid reservoir, sample
reservoir, evacuated container, fluid source, etc.). The distal end
portion 132 of the catheter 130 is configured to be inserted into a
portion of a patient's body, as described in further detail
herein.
[0048] At least a portion of the catheter 130 is movably disposed
within the housing 110. In some embodiments, the catheter 130 can
be moved (e.g., via movement of the actuator 150) between a first
position and a second position to transition the device 100 between
the first configuration and the second configuration, respectively.
More specifically, the distal end portion 132 of the catheter 130
is disposed within the housing 110 when the catheter 130 is in the
first position (FIG. 1) and at least a portion of the catheter 130
(e.g., the distal end portion 132) extends through the second port
112 and the PIV (not shown) to place a distal end of the catheter
130 in a distal position relative to the PIV when the catheter 130
is in the second position (FIG. 2), as described in further detail
herein.
[0049] The catheter 130 can be formed from any suitable material or
combination of materials such as those described above. In some
embodiments, the catheter 130 can be formed from a material or
combination of materials and/or can have a size, shape, diameter,
thickness, etc. to result in any suitable stiffness, flexibility,
hardness, and/or durometer. In some embodiments, at least a portion
of the catheter 130 can be formed of a braided material or the
like, which can change, modify, and/or alter a flexibility of the
catheter 130 in response to a bending force or the like. In some
embodiments, forming the catheter 130 of the braided material or
the like can reduce a likelihood of kinking, pinching, bending,
and/or otherwise deforming in an undesired manner. In addition,
forming at least a portion of the catheter 130 of a braided
material can result in a compression and/or deformation in response
to a compression force exerted in a direction of a longitudinal
centerline defined by the catheter 130 (e.g., an axial force or the
like). In this manner, the catheter 130 can absorb a portion of
force associated with, for example, hitting an obstruction or the
like.
[0050] The catheter 130 can be any suitable shape, size, and/or
configuration. In some embodiments, the catheter 130 can have a
length, diameter, and/or configuration that is based at least in
part on a one or more characteristics and/or aspects of the access
device to which the device 100 is configured to be coupled. For
example, in some embodiments, at least a portion of the catheter
130 can have an outer diameter (e.g., between 8-gauge and 33-gauge,
and/or any other suitable size or range of sizes) that is
substantially similar to or slightly smaller than an inner diameter
defined by a portion of the second port 112 and/or an inner
diameter defined by a portion of the access device to which the
second port 112 is coupled (e.g., a PIV, extended-dwell PIV,
midline, PICC line, etc.). In this manner, an inner surface of the
second port 112 and/or PIV can guide the catheter 130, as it is
moved therethrough, as described in further detail herein. In some
embodiments, such an arrangement can limit and/or can substantially
prevent bending, deforming, and/or kinking of a portion of the
catheter 130 during use.
[0051] In some embodiments, the catheter 130 can have a length
sufficient to place a distal surface of the catheter 130 in a
desired position within and/or relative to the access device when
the catheter 130 is in the second position. In some embodiments,
the length of the catheter 130 can be sufficient to define a
predetermined, desired, and/or at least a threshold distance
between the distal surface of the catheter 130 and the distal
surface of the PIV when the catheter 130 is in the second position.
In some instances, placing the distal surface of the catheter 130
at the predetermined, desired, and/or at least the threshold
distance from the distal surface of the PIV can, for example, place
the distal surface of the catheter 130 in a desired position within
a vein, as described in further detail herein. In some embodiments,
the catheter 130 can include markings or indications that can be
used to determine the distance between the distal surface of the
catheter 130 and the distal surface of the PIV when the catheter
130 is in the second position. Moreover, the catheter 130 can have
a length that is sufficient to place the distal surface of the
catheter 130 in a desired position relative to the distal surface
of an access device having a relatively long length when fully
extended (e.g., in the second position) and thus, when the device
100 is coupled to an access device having a relative short length,
the distal surface of the catheter 130 can be placed in the desired
position relative to a distal surface of the shorter access device
without being fully extended.
[0052] In some embodiments, for example, the predetermined,
desired, and/or threshold (e.g., minimum) distance between the
distal surface of the catheter 130 and the distal surface of the
access device (e.g., PIV) can be between about 0.0 millimeters (mm)
and about 50.0 mm (about 0.0 inches (in) to about 2 in). In other
embodiments, the predetermined, desired, and/or threshold distance
can be between about 15.0 mm and about 30.0 mm (about 0.59 in and
about 1.18 in). In still other embodiments, the distal end portion
132 of the catheter 130 can be advanced, for example, through a hub
of the access device while remaining proximal to the distal surface
of the access device (e.g., the distal end portion 132 of the
catheter 130 does not extend through the access device). For
example, in some embodiments, the predetermined and/or desired
distance between the distal surface of the catheter 130 and the
distal surface of the access device can be when the distal surface
of the catheter 130 is between about 80.0 mm and about 0.0 mm
(about 3.15 in and about 0.0 in) proximal to the distal surface of
the access device (e.g., -80.0 mm to about 0.0 mm).
[0053] In some embodiments, the length of the catheter 130 can be
based at least in part on a desired and/or intended use. For
example, in some embodiments, the device 100 can be configured for
use in interventional cardiology wherein the catheter 130 can have
a length of, for example, 320.0 centimeters (cm) (about 12.60 in)
or more. In other embodiments, the device 100 can be configured for
use in fluid transfer via a PIV (e.g., a standard or short PIV, an
extended dwell PIV, a midline, etc.) and can have a length between
about 1.77 cm and about 25.4 cm (about 0.5 inches (in) and about
10.0 in).
[0054] In some embodiments, the length of the catheter 130 can be
greater than a length of the housing 110. Moreover, a length of a
portion of the catheter 130 disposed in the housing 110 can be
greater than the length of the housing 110 and/or at least a length
of a line extending between the first port 111 and the second port
112 of the housing 110. For example, in some embodiments, the
portion of the catheter 130 disposed in the housing 110 can form
and/or can be arranged in a U-shaped configuration forming a U-bend
or 180.degree. turn in the housing. In other embodiments, the
portion of the catheter 130 disposed in the housing can form and/or
can be arranged in any suitable manner and/or with any suitable
angle of turn from no turn (0.degree.) to a complete turn
(360.degree.) or to more than a complete turn (e.g., can form any
number of loops or any suitable portions thereof). In other
embodiments, the portion of the catheter 130 disposed in the
housing 110 can be arranged a spiral configuration, a coil
configuration, and/or any other circuitous, tortuous, or
substantially non-linear configuration.
[0055] Accordingly, the arrangement of the catheter 130 disposed in
the housing 110 can result in an increased "reach" of the catheter
130 for a given length of the housing 110. In some implementations,
such an arrangement can allow the device 100 to be used with access
devices and/or the like having a relatively long length such as,
for example, extended-dwell PIVs, midline PIVs, PICC lines, and/or
the like. In other implementations, the arrangement of the catheter
130 disposed in the housing 110 can allow a length of the housing
110 to be reduced without a similar or corresponding reduction in
the length or reach of the catheter 130. Moreover, the arrangement
of the catheter 130 within the housing 110 can result in a shorter
unsupported portion of the catheter 130 when compared to an
unsupported portion of a catheter having a straight or linear
configuration, which can reduce a likelihood of undesired bowing,
kinking, bending, deflecting, and/or deforming, as the catheter 130
is advanced to the second position.
[0056] The actuator 150 of the device 100 can be any suitable
shape, size, and/or configuration. The actuator 150 is coupled to
the housing 110 and the catheter 130. More specifically, the
actuator 150 can be a rotary actuator or mechanism that includes a
first portion disposed outside of the housing 110 and a second
portion disposed within the housing 110. In this manner, a user can
engage the first portion to move the actuator 150 relative to the
housing 110 by rotating the actuator 150, as indicated by the
arrows AA in FIGS. 1 and 2. In some embodiments, the housing 110
can define a range of motion of the actuator 150. For example, in
some embodiments, can include a structure, feature, component,
and/or the like that can selectively engage a portion of the
actuator 150 to limit, restrict, guide, and/or otherwise direct an
amount or direction of movement of a portion of the actuator 150.
That is to say, the actuator 150 can be rotated through a desired
range of motion and/or through a desired angular displacement based
at least in part on a size and/or arrangement of a portion of the
actuator 150 and a size and/or arrangement of a portion of the
actuator housing 110. As described in further detail herein, the
actuator 150 can be actuated (e.g., rotated) to advance the
catheter 130 between a first position (FIG. 1) and a second
position (FIG. 2).
[0057] Although not show in FIGS. 1 and 2, the second portion of
the actuator 150 is coupled to and/or in contact with the catheter
130. For example, in some embodiments, the second portion of the
actuator 150 can be and/or can include a relatively rigid member,
mechanism, sleeve, and/or the like that defines a lumen or channel
configured to movably receive a portion of the catheter 130. In
some embodiments, the lumen or channel of the second portion can
have a U-shape configuration, a bent configuration, a spiral
configuration, a coil configuration, a circuitous or tortuous
configuration, and/or the like. In some embodiments, the second
portion and/or the lumen or channel defined by the second portion
can have any suitable radius of curvature and any suitable surface
configured to engage, direct, and/or control at least a portion of
the catheter 130.
[0058] In other embodiments, the second portion of the actuator 150
can be a wheel, disc, gear, sprocket, and/or the like configured to
contact a portion of the catheter 130 and/or a member coupled to
the catheter 130. In such embodiments, the arrangement of the
second portion and the catheter 130 is such that an outer surface
of the catheter 130 can contact the second portion of the actuator
150 such that a friction force resulting from the contact at least
partially resists movement of the catheter 130 against the second
portion of the actuator 150. In this manner, when the actuator 150
is rotated relative to the housing 110, the second portion of the
actuator 150 advances the catheter 130 in a direction that is
tangent (or substantially tangent) to a point (or area) of contact
between the second portion of the actuator 150 and the catheter
130.
[0059] The arrangement of the device 100 can be such that
rotational movement of the actuator 150 about a given axis in the
housing 110 advances a portion of the catheter 130 engaged with the
actuator 150 (e.g., the second portion of the actuator 150), which
in turn, moves the catheter 130 between the first position and the
second position. As described above, the proximal end portion 131
of the catheter 130 is coupled to and/or otherwise extends through
the first port 111 while the distal end portion 132 of the catheter
130 is configured to be moved relative to the housing 110 (e.g.,
through the second port 112). Thus, as shown in FIG. 2, rotating
the actuator 150 in a counterclockwise direction (e.g., the AA
direction) advances a portion of the catheter 130 about the axis of
the actuator 150 (e.g., about the second portion of the actuator
150, not shown). In response, the distal end portion 132 of the
catheter 130 is moved from the first position (FIG. 1) to the
second position (FIG. 2).
[0060] In some embodiments, the arrangement of the catheter 130 can
be such that the proximal end portion 131 of the catheter 130 is
fixedly coupled to and/or otherwise maintained in a fixed position
relative to the first port 111. As such, rotating the actuator 150
through a rotational and/or angular displacement can advance, coil
(or uncoil), spool (or unspool), and/or otherwise move the portion
of the catheter 130 disposed within the housing 110. In other
words, the proximal end position 131 can be maintained in a
substantially fixed position relative to the housing 110 as the
catheter 130 is moved between the first position and the second
position. In other embodiments, the proximal end portion of the
catheter 130 can be movably coupled to and/or movably received by
the first port 111. As such, rotating the actuator through a
rotational and/or angular displacement can advance, coil (or
uncoil), spool (or unspool), and/or otherwise move all or
substantially all of the catheter 130 relative to the housing 110
in response to actuation of the actuator 150. In this manner,
whether the proximal end portion 131 of the catheter 130 is fixedly
or movably coupled to the first port 111 of the housing 110, the
arrangement of the device 100 can be such that the housing 110 has
a relatively compact, limited, and/or reduced length while the
catheter 130 has a length sufficient to extend a desired distance
(e.g., at least partially into or through a standard or short PIV,
an extended-dwell PIV, a midline PIV, a PICC line, and/or any other
suitable access device).
[0061] FIGS. 3 and 4 illustrate a fluid transfer device 200,
according to another embodiment. The fluid transfer device 200
(also referred to herein as "device") includes a housing 210, a
catheter 230, and an actuator 250. As shown in FIGS. 3 and 4, the
housing 210 is an elongate member, tube, housing, introducer, etc.
In some embodiments, the housing 210 can be substantially straight
and/or linear with a relatively small interior cross-sectional
shape. As described above with reference to the housing 110, the
housing 210 shown in FIGS. 3 and 4 includes a first port 211 (e.g.,
a proximal port) and a second port 212 (e.g., a distal port). The
ports 211 and 212 can be any suitable coupling mechanism, lock,
port, opening, cap, etc., and can be the same configuration or
different configurations. That is to say, the first port 211 can be
similar to the second port 212 or different from the second port
212. Moreover, the second port 212 is configured to be coupled to
an access device such as, for example, a PIV, extended-dwell PIV,
midline, PICC line, and/or the like.
[0062] The catheter 230 can be any suitable lumen-defining device.
For example, in some embodiments, the catheter 230 can be similar
to or substantially the same as the catheter 130 described above
with reference to FIGS. 1 and 2. Accordingly, portions and/or
aspects of the catheter 230 may not be described in further detail
herein.
[0063] As shown in FIGS. 3 and 4, the catheter 230 is configured to
be at least partially and/or temporarily disposed in the housing
210. More particularly, the catheter 230 includes a proximal end
portion 231 that is coupled to, received by, and/or otherwise
positioned at or near the first port 211 and a distal end portion
232 that is coupled to, received by, and/or otherwise positioned at
or near the second port 212. In the embodiment shown in FIGS. 3 and
4, the proximal end portion 231 of the catheter 230 is movably
coupled to and/or otherwise received by the first port 211. For
example, the first port 211 can be configured to allow at least the
proximal end portion 231 of the catheter 230 to move therethrough.
In some embodiments, the proximal end portion 231 of the catheter
230 can be coupled to a secondary catheter or the like configured
to place the catheter 230 in fluid communication with a fluid
source, fluid reservoir, and/or any other suitable device. In other
embodiments, the proximal end portion 231 of the catheter 231 can
movably extend, at least in part, through the first port 211. As
shown in FIGS. 3 and 4, the distal end portion 232 of the catheter
230 is configured to be movably coupled to and/or otherwise
received by the second port 212 of the housing 210. As such, at
least a portion of the catheter 230 disposed between the proximal
end portion 231 and the distal end portion 232 is disposed within
the housing 210.
[0064] The actuator 250 can be any suitable member, mechanism,
device etc. For example, in some embodiments, the actuator 250 can
be substantially similar in at least form and/or function to the
actuator 150 described above with reference to FIGS. 1 and 2. As
shown in FIGS. 3 and 4, the actuator 250 includes a first portion
251 and a second portion 252. The actuator 250 can be coupled to
the housing 210 at or near the second port 212 of the housing 210
(e.g., at or near a distal end portion of the housing 210). In
other embodiments, the actuator 250 can be coupled to the housing
210 at any suitable position along a length of the housing 210. The
actuator 250 can be coupled to the housing 210 in any suitable
manner that allows the actuator 250 to be rotated relative to the
housing 210. Moreover, the actuator 250 can be coupled to the
housing 210 such that the second portion 252 is at least partially
disposed within the housing 210 and in contact with and/or
otherwise allowed to engage the catheter 230.
[0065] As described above with reference to the actuator 150, the
actuator 250 is configured such that rotational movement of the
actuator 250, results in the second portion 252 of the actuator 250
engaging the catheter 230, thereby moving the catheter 230 in a
linear direction between a first position (e.g., a proximal
position as shown in FIG. 3) and a second position (e.g., a distal
position as shown in FIG. 4). More specifically, in use, the device
200 can be in a first configuration and/or state in which at least
the distal end portion of the catheter is 230 is disposed within
the housing 210 (FIG. 3) and a user can manipulate the device 200
by engaging the first portion 251 of the actuator 250 to place the
device 200 in a second configuration and/or state. For example, the
user can exert a force on the first portion 251 of the actuator 250
to rotate the actuator in, for example, a clockwise direction, as
indicated by the arrow BB in FIG. 4. As such, the second portion
252 of the actuator 250 rotates relative to the housing 210 and
engages the catheter 230 to move the catheter 230 in the distal
direction, as indicated by the arrow CC in FIG. 4. Thus, when the
second port 212 of the housing 210 is coupled to an access device
or the like (not shown in FIGS. 3 and 4), the catheter 230 can be
advanced to a desired position relative to the access device, as
described above with reference to the device 100.
[0066] In some embodiments, a ratio of angular displacement of the
actuator 250 relative to linear displacement of the catheter 230
can be tuned and/or selected such that the catheter 230 is moved
with a desired set of characteristics. For example, the device 200
can be preset such that a known number of turns or portions of a
turn (e.g., 1/2 turn, 1 turn, 10 turns, etc.) can result in a known
amount of advancement of the distal end portion 232 of the catheter
230. In some embodiments, the device 200 can be configured with a
mechanical advantage, gearing, etc. that can result in a "length
multiplying" and/or "displacement multiplying" effect such that a
relatively small amount of rotation of the actuator 250 results in
a relatively large amount of translation of the distal end portion
232 of the catheter 230. When accessing a vein or the like via the
access device coupled to the second port 212, the linear
displacement of at least the distal end portion 232 of the catheter
230 can be sufficient to place a distal surface of the catheter 230
in a desired position relative to a distal surface of the access
device regardless of the type and/or length of the access device.
For example, in some instances, it may be desirable to position the
distal surface of the catheter 230 distal to the distal surface of
the access device. In such instances, the arrangement of the device
200 can be such that the housing 210 has a compact, limited, and/or
reduced length while the catheter 230 has a length sufficient to
extend beyond a distal end of the access device (e.g., a PIV or the
like).
[0067] In some embodiments, the arrangement of the actuator 250 and
catheter 230 can also be tuned and/or selected based at least in
part on an amount of force exerted on the actuator 250 to rotate
the actuator 250 and/or an amount of force associated with
advancing the catheter 230. For example, in some embodiments, the
arrangement of the actuator 250 and catheter 230 can be such that
the distal end portion 232 of the catheter 230 is advanced in
response to a relatively small amount of force being applied on the
actuator 250 (e.g., via a mechanical advantage, gearing, etc.). In
some embodiments, an amount of a friction force between the second
portion 252 of the actuator 250 and the catheter 230 can be
increased or decreased to allow for a desired amount of slipping
between the second portion 252 and the catheter 230 in response to
the catheter hitting an obstruction or the like. In some instances,
reducing an amount of force associated with advancement of the
catheter 230 can reduce and/or limit damage to the catheter 230
and/or other structure (e.g., a vein wall or portion of the access
device) that may otherwise result from the distal surface of the
catheter 230 hitting an obstruction or the like.
[0068] FIGS. 5 and 6 illustrate a fluid transfer device 300
according to another embodiment. The fluid transfer device 300
(also referred to herein as "device") can be substantially similar
to the devices 100 and/or 200 in at least some aspects of its
structure and/or function. The device 300 includes a housing 310
and a catheter 330. The housing 310 includes a first port 311
configured to receive a proximal end portion 331 of the catheter
330 and a second port 312 configured to receive a distal end
portion 332 of the catheter 330, as described above with reference
to the devices 100 and/or 200. As shown in FIGS. 5 and 6, the
housing 310 can be an elongate member, tube, introducer, sheath,
and/or the like that includes and/or forms a loop or a complete
360.degree. turn between the first port 311 and the second port
312. For example, in some embodiments, the housing 310 can be a
relatively rigid member (e.g., formed from a relatively hard
plastic and/or the like) that is formed or molded into the looped
shape or configuration. In other embodiments, the housing 310 can
be formed from a relatively flexible material or the like that can
allow the housing 310 to be bent, formed, curved, and/or otherwise
reconfigured. In such embodiments, a user can manipulate the device
300 to place the housing 310 in any suitable shape and/or
configuration. In some implementations, the housing 310 can be
formed and/or placed into a shape or configuration that reduces,
for example, an overall length and/or size of the device 300.
[0069] As described above with reference to the devices 100 and/or
200, the catheter 330 of the device 300 is configured to be at
least partially disposed in the housing 300 and can be transitioned
and/or moved between at least a first position (e.g., a proximal
position) and a second position (e.g., a distal position). As
shown, the catheter 330 includes a proximal end portion 331 that is
coupled to, received by, and/or otherwise positioned at or near the
first port 311 and a distal end portion 332 that is coupled to,
received by, and/or otherwise positioned at or near the second port
312. In the embodiment shown in FIGS. 5 and 6, the proximal end
portion 331 of the catheter 330 is movably coupled to and/or
otherwise received by the first port 311, as described above with
reference to the catheter 330. The distal end portion 332 of the
catheter 330 is configured to be movably coupled to and/or
otherwise received by the second port 312 of the housing 310. As
such, at least a portion of the catheter 330 disposed between the
proximal end portion 331 and the distal end portion 332 is disposed
within the housing 310. In some embodiments, the turned or looped
configuration of the housing 310 can be such that a length of the
catheter 330 is longer than a length or distance between the first
port 311 and the second port 312. Accordingly, the catheter 330 can
have any desirable length or "reach" without substantially
increasing an overall length of the device 300. While the housing
310 is shown as forming a single loop, circle, coil, turn, etc., it
should be understood that a housing can include any number of loops
or turns, thereby allowing for any suitable catheter length.
[0070] In the embodiment shown in FIGS. 5 and 6, a user can engage,
for example, the proximal end portion 331 of the catheter 330 to
move or transition the catheter 330 between the first position and
the second position. For example, the device 300 can be in a first
configuration and/or state in which the catheter 330 is in the
first position (FIG. 5) and the user can exert a force on the
proximal end portion 331 of the catheter 330 to move the catheter
330 in a distal direction toward the second position, as indicated
by the arrows DD in FIG. 6. Similarly, the user can engage a
portion of the catheter 330 to move the catheter 330 from the
second position to or toward the first position (e.g., after
use).
[0071] While the device 300 is shown and described above as being
actuated in response to a force exerted on a portion of the
catheter 330, in other embodiments, a device having a similar shape
and/or configuration can include any suitable actuator configured
move and/or transition the catheter 330. For example, in some
embodiments, a device can include a slider or the like that can be
slid and/or otherwise moved to move a catheter between a first
position and a second position. In other embodiments, a device can
include an actuator that is similar to the actuator 250 described
above with reference to FIGS. 3 and 4.
[0072] For example, FIGS. 7 and 8 illustrate of a fluid transfer
device 400 in a first configuration and second configuration,
respectively, according to another embodiment. The fluid transfer
device 400 (also referred to herein as "device") can be any
suitable shape, size, and/or configuration. For example, at least a
portion of the device 400 can be similar to and/or substantially
the same as one or more portions (and/or combination of portions)
of the devices 100, 200, and/or 300 described above. For example,
as described in further detail herein, the device 400 can be a
combination of certain portions and/or aspects of the devices 200
and 300. Thus, portions of the device 400 may not be described in
further detail herein.
[0073] The device 400 includes at least a housing 410, a catheter
430, and an actuator 450. The housing 410 can be any suitable
configuration. For example, in some embodiments, the housing 410
can be an elongate member having a substantially circular
cross-sectional shape. The housing 410 includes a first port 411
configured to receive a proximal end portion 431 of the catheter
430 and a second port 412 configured to receive a distal end
portion 432 of the catheter 430, as described above with reference
to the devices 100, 200, and/or 300. In some embodiments, the
housing 410 can be similar to and/or substantially the same as the
housing 310 described above. For example, as shown in FIGS. 7 and
8, the housing 410 can be formed, molded, and/or otherwise placed
into a bent, curved, looped, coiled, and/or spiraled shape or
configuration. Thus, the housing 410 and/or aspects thereof are not
described in further detail herein.
[0074] The catheter 430 of the device 400 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 430 can be substantially similar to any
of the catheters 130, 230, and/or 330 described above. For example,
as described above with reference to the catheter 130, the catheter
430 can be formed from a material or combination of materials and
can have a size, shape, diameter, thickness, and/or durometer
configured to allow at least a portion of the catheter 430 to be
moved from a first position to a second position (e.g., related to
the housing 410) without undesirable bending, deforming, kinking,
etc. Moreover, in some embodiments, the size, shape, diameter,
length, and/or configuration of the catheter 430 may be based, at
least in part, on one or more characteristics and/or aspects of an
access device to which the device 400 is configured to be coupled,
as described in detail above with reference to the catheter 130.
Accordingly, such similar portions and/or aspects of the catheter
430 are not described in further detail herein.
[0075] At least a portion of the catheter 430 is movably disposed
within the housing 410. In some embodiments, the catheter 430 can
be moved between a first position, in which the distal end portion
432 of the catheter 430 is disposed within the housing 410 (FIG.
7), and a second position, in which at least a portion of the
catheter 430 extends through the second port 412 and at least a
portion of an access device (not shown) to which the second port
412 is coupled. In some embodiments, the catheter 430 can have a
length sufficient to place a distal surface of the catheter 430 in
a desired position relative to a distal surface of the PIV when the
catheter 430 is in the second position. In some embodiments, the
arrangement of the housing 410 and the catheter 430 can be
substantially similar to the arrangement of the housing 310 and the
catheter 330 described above with reference to FIGS. 5 and 6.
[0076] The device 400 can differ from the device 300, however, with
the inclusion of the actuator 450, which can be used to move or
transition the catheter 430 between the first position and the
second position. The actuator 450 can be any suitable member,
mechanism, device etc. For example, as shown in FIGS. 7 and 8, the
actuator 450 includes a first portion 451 and a second portion 452.
The actuator 450 can be coupled to the housing 410 at or near the
second port 412 of the housing 410 (e.g., at or near a distal end
portion of the housing 410). In other embodiments, the actuator 450
can be coupled to the housing 410 at any suitable position along a
length of the housing 410. The actuator 450 can be coupled to the
housing 410 in any suitable manner that allows the actuator 450 to
be rotated relative to the housing 410. Moreover, the actuator 450
can be coupled to the housing 410 such that the second portion 452
is at least partially disposed within the housing 410 and in
contact with and/or otherwise allowed to engage the catheter 430.
In this manner, the actuator 450 can be substantially similar in at
least form and/or function to the actuator 250 described above with
reference to FIGS. 3 and 4.
[0077] In use, the device 400 can be in a first configuration
and/or state in which at least the distal end portion of the
catheter is 430 is disposed within the housing 410 (FIG. 7) and a
user can manipulate the device 400 by engaging the first portion
451 of the actuator 450 to place the device 400 in a second
configuration and/or state (FIG. 8). For example, the user can
exert a force on the first portion 451 of the actuator 450 to
rotate the actuator in, for example, a clockwise direction, as
indicated by the arrow EE in FIG. 8. As such, the second portion
452 of the actuator 450 rotates relative to the housing 410 and
engages the catheter 430 to move the catheter 430 in the distal
direction, as indicated by the arrow FF in FIG. 8. Thus, when the
second port 412 of the housing 410 is coupled to an access device
or the like (not shown), the catheter 430 can be advanced to a
desired position relative to the access device, as described in
detail above with reference to the device 100.
[0078] FIGS. 9 and 10 are schematic illustrations of a fluid
transfer device 500 in a first configuration and second
configuration, respectively, according to another embodiment. The
fluid transfer device 500 (also referred to herein as "device") can
be any suitable shape, size, and/or configuration. For example, at
least a portion of the device 500 can be similar to and/or
substantially the same as one or more portions (and/or combination
of portions) of the devices 100, 200, 300, and/or 400 described
above. Thus, portions of the device 500 may not be described in
further detail herein.
[0079] The device 500 includes at least a housing 510, a catheter
530, and an actuator 550. The housing 510 can be any suitable
configuration. In some embodiments, the shape of the housing 510
and/or one or more features and/or surface finishes of at least an
outer surface of the housing 510 can be arranged to increase the
ergonomics of the device 500, which in some instances, can allow a
user to manipulate the device 500 with one hand (i.e.,
single-handed use). In some embodiments, portions and/or aspects of
the housing 510 can be substantially similar to portions and/or
aspects of the housings 110, 210, 310, and/or 410. Thus, such
portions and/or aspects of the housing 510 may not be described in
further detail herein.
[0080] The housing 510 has a first port 511 and a second port 512.
The ports 511 and 512 can be any suitable configuration such as
those described above with reference to the first port 111 and the
second port 112, respectively. In the embodiment shown in FIGS. 9
and 10, the first port 511 extends, for example, from a proximal
end or side of the housing 510 and the second port 512 extends, for
example, from a distal end or side of the housing 510 (e.g.,
opposite the proximal end or side). The first port 511 is
configured to fixedly or movably receive and/or couple to a
proximal end portion 531 of the catheter 530. The second port 512
is configured to movably receive a distal end portion 532 of the
catheter 530. Moreover, the second port 512 can be a lock mechanism
and/or coupler configured to couple the device 500 to an access
device or the like such as, for example, a PIV 505 (e.g., an
indwelling PIV), as described above.
[0081] The catheter 530 of the device 500 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 530 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
and/or 430 described above. Thus, such similar portions and/or
aspects of the catheter 530 may not described in further detail
herein. For example, as described above with reference to the
catheter 130, in the embodiment shown in FIGS. 9 and 10, the
catheter 530 can be formed from any suitable material such as those
described herein. Similarly, the catheter 530 can have any suitable
diameter configured to allow at least a portion of the catheter 530
to be moved through the second port 512 without undesirable
bending, deforming, kinking, etc., and can have any suitable length
that can be at least partially based on one or more characteristics
of the access device (e.g., the PIV 505) to which the device 500 is
coupled, as described above with reference to the catheter 130.
[0082] Although not shown in FIGS. 9 and 10, the catheter 530
defines a lumen that extends through the proximal end portion 531
and the distal end portion 532. The proximal end portion 531 of the
catheter 530 includes and/or is coupled to a coupler 533 (e.g., a
Luer Lok.TM. or the like) configured to physically and fluidically
couple the catheter 530 to any suitable device and/or reservoir
(e.g., a syringe, fluid reservoir, sample reservoir, evacuated
container, fluid source, etc.). The distal end portion 532 of the
catheter 530 is configured to be inserted into and/or through at
least a portion of the indwelling PIV 505 and, in some instances,
into a portion of a patient's body, as described in further detail
herein.
[0083] At least a portion of the catheter 530 is movably disposed
within the housing 510. In some embodiments, the catheter 530 or a
portion thereof can be moved (e.g., via rotational movement of the
actuator 550) between a first position, in which the distal end
portion 532 of the catheter 530 is disposed within the housing 510
(FIG. 9) and/or the second port 512, and a second position, in
which at least a portion of the catheter 530 extends through the
second port 512 and at least a portion of the PIV 505 (FIG. 10). In
some embodiments, the catheter 530 can have a length sufficient to
place a distal surface of the catheter 530 in a distal position
relative to a distal surface of the PIV 505 when the catheter 530
is in the second position. In other words, the length of the
catheter 530 can be sufficient to define a predetermined, desired,
and/or threshold distance between the distal surface of the
catheter 530 and the distal surface of the PIV 505 when the
catheter 530 is in the second position. In some instances, placing
the distal surface of the catheter 530 at the predetermined,
desired, and/or threshold distance from the distal surface of the
PIV 505 can, for example, place the distal surface of the catheter
530 in a desired position within a vein, as described in detail
above with reference to the catheter 130.
[0084] In some embodiments, the length of the catheter 530 can be
greater than a length of the housing 510 and/or at least a length
of a line or axis defined between the first port 511 and the second
port 512 of the housing 510. In some embodiments, the length of the
catheter 530 can be many times greater than a length of the housing
510. For example, as described above with reference to the catheter
130, the catheter 530 can be disposed in the housing 510 in a wound
or coiled arrangement including one or more complete coils (e.g.,
360.degree. turns) of the catheter 530 around at least a portion of
the actuator 550 disposed within the housing 510. Although not
shown in FIGS. 9 and 10, in some embodiments, one or more portions,
sections, ends, etc. of the catheter 530 can be coupled to a
portion of the actuator 550, which can allow at least a portion of
the catheter 530 to be wound, spooled, coiled, etc. around the
portion of the actuator 550, as described in further detail herein.
In some embodiments, the housing 510 can include, form, and/or
define a circular portion around a shaft associated with the
actuator 550 within which at least a portion of the catheter 530
can be wound or coiled around the shaft in the circular portion to
form one or more 360.degree. turns (e.g., one complete turn, at
least one complete turn and any suitable fraction of a complete
turn, or multiple complete turns).
[0085] The portion of the catheter 530 disposed in the housing 510
can be of any suitable length. For example, in some embodiments,
the length of the catheter 530 can be several times the length of
the housing 510 without increasing a length of the housing 510, as
described above with reference to the device 100 shown in FIGS. 1
and 2. Moreover, in some embodiments, the wound or coiled
configuration of the catheter 530 can result in the catheter 530
being in a taut or supported configuration, which can reduce a
portion of the catheter 530 that is unsupported within the housing
510. Such an arrangement can, for example, reduce a likelihood of
undesired kinking, bending, bowing, deflecting, deforming, etc. of
a portion of the catheter 530 as the catheter 530 is moved between
the first position and the second position. In other words,
reducing an unsupported length of the catheter 530 can result in
the catheter 530 being more "pushable" (e.g., able to be advanced
without undesired reconfiguration) from the first position to the
second position. Moreover, in some embodiments, the housing 510 can
include one or more internal structures 514 such as one or more
walls, partitions, protrusions, ridges, ribs, channels, rollers,
etc. configured to support and/or guide the catheter 530, as shown
in FIGS. 9 and 10. While the internal structure 514 is particularly
shown in FIGS. 9 and 10, a housing and/or any other portion of a
device can include support structures that can act as a fence,
post, rib, bumper, etc. configured to support the catheter as it is
"pushed" and/or otherwise moved (e.g., advanced, retracted, etc.).
In some embodiments, the support structures can be arranged in a
direction of an axial force exerted along the catheter. In some
embodiments, the support structures can be, for example, tangential
to an exerted force and/or a movement or rotation of the catheter
(or portion(s) thereof).
[0086] The actuator 550 of the device 500 can be any suitable
shape, size, and/or configuration. As shown in FIGS. 9 and 10, the
actuator 550 is movably coupled to the housing 510. The actuator
550 includes a first portion 551 (e.g., an engagement portion)
disposed outside of the housing 510 and a second portion 552 (e.g.,
a shaft portion) disposed within the housing 510 and configured to
engage and/or otherwise contact a portion of the catheter 530. The
first portion 551 of the actuator 550 can be arranged as a rotary
switch, rotary button, tab, knob, dial, etc. The second portion 552
of the actuator 550 can be, for example, a relatively rigid sleeve,
tube, rod, shaft, drum, spool, and/or the like. The second portion
552 can be substantially cylindrical and/or can have a circular
cross-sectional shape and can have any suitable radius of
curvature. In some embodiments, the second portion 552 of the
actuator 550 can include and/or can define a channel, conduit,
and/or the like within or along which a portion of the catheter 530
can be wound.
[0087] In some embodiments, the catheter 530 is wound around the
second portion 552 (e.g., the shaft portion) in or along a path
formed or defined, at least in part, by the second portion 552 of
the actuator 550. In some embodiments, a portion of the catheter
530 is disposed in a conduit and/or lumen that is operatively
coupled to the second portion 552 of the actuator 550 such that a
rotational movement of the actuator 550 results in a rotational
movement of at least a portion of the catheter 530 that is wound or
coiled around the second portion 552. Such an arrangement, in turn,
results in a spooling (or unspooling), coiling (or uncoiling),
winding (or unwinding), etc. of at least a portion of the catheter
530, thereby moving and/or transitioning the catheter 530 between
the first position (FIG. 9) and the second position (FIG. 10). In
some embodiments, the catheter 530 can have two sections (or the
device can include two catheters), which can allow the catheter 530
to be coupled to the second portion 552 of the actuator 550. For
example, in some embodiments, the proximal end portion 531 of the
catheter 530 can be a first section or first catheter that is
fixedly coupled to the first port 511 of the housing 510 and
coupled to a port or the like (not shown) of the actuator 550. A
medial portion of the catheter 530 (or an end portion of a second
catheter) similarly can be coupled to a port of the actuator 550
and in fluid communication with the proximal end portion 531 of the
catheter 530. In such embodiments, coupling the medial portion of
the catheter 530 to the actuator 550 can allow a section of the
catheter 530 to be spooled or coiled around the second portion 552
of the actuator 550. Moreover, distal end portion 532 of the
catheter 530 can extend from the second portion 552 of the actuator
550 to the second port 512, as shown in FIG. 9.
[0088] In some implementations, the distal end portion 532 of the
catheter 530 can be at least partially disposed within and/or
otherwise aligned with the second port 512 such that the rotation
of the actuator 550 and the portion of the catheter 530 spooled
and/or coiled about the second portion 552 of the actuator 550
results in a substantially linear movement of the distal end
portion 532 of the catheter 530 relative to, within, and/or through
the second port 512. Moreover, the one or more internal structures
514 of the housing 510 can support and/or guide at least a portion
of the catheter 530 as the catheter 530 is moved and/or
transitioned between the first position and the second position. In
some embodiments, the radius of curvature of the second portion 552
can be such that the portion of the catheter 530 can move and/or
transition between the first position and the second position
without kinking, bending, binding, and/or otherwise undesirably
deforming.
[0089] Although not shown in FIGS. 9 and 10, in some embodiments,
an outer surface of the housing 510 and/or a surface defining at
least a portion thereof can include and/or can form a set of ribs,
ridges, bumps, notches, etc. configured to be in contact with a
surface of the actuator 550. In such embodiments, the surface of
the actuator 550 can move along the ribs or the like as the
actuator 550 is rotated relative to the housing 510. As such, the
movement can result in a haptic and/or audible output that can
provide a user with an indicator or the like associated with a
relative amount of rotation of the actuator 550 and/or a
corresponding relative movement (e.g., linear movement) of the
catheter 530. In some embodiments, the arrangement of the ribs or
the like and the actuator 550 can act as a friction system or the
like that can, for example, retain the actuator 550 (and thus, the
catheter 530) in a substantially fixed rotational and/or angular
position in the absence of an external force being applied on the
actuator 550 (e.g., a torque or turning force applied by the
user).
[0090] The arrangement of the device 500 is such that moving the
actuator 550 (e.g., the first portion 551 and the second portion
552, collectively) about an axis defined in the housing 510 and/or
otherwise relative to the housing 510 advances a portion of the
catheter 530 along and/or through a path defined within the housing
510. For example, when the device 500 is in a first configuration
or state (FIG. 9), rotation of the actuator 550 in a clockwise
direction moves the catheter 530 from the first position and the
second position (FIG. 10). In some implementations, the proximal
end portion 531 of the catheter 530 coupled between the first port
511 and the second portion 552 of the actuator 550 and the medial
portion (and/or any other suitable portion) of the catheter 550
also being coupled to the second portion 552 of the actuator 550
and at least partially spooled or coiled thereabout, rotating the
actuator 550, for example, advances a portion of the catheter 530
along and/or through the path (not shown) defined within the
housing 510, which in turn, moves the distal end portion 532 of the
catheter 530 relative to the second port 512 and/or the access
device coupled thereto (e.g., the PIV 505).
[0091] As described above, the arrangement of the device 500 is
such that moving the actuator 550 an angular amount or distance
(e.g., an amount of rotation) results in the distal end portion 532
of the catheter 530 being moved a linear amount or distance. In
other words, linear displacement (e.g., translation) of the distal
end portion 532 of the catheter 530 is achieved with the angular
displacement (e.g., rotation) of the actuator 550. In some
embodiments, the ratio of angular displacement to linear
displacement can be predetermined. For example, the device 500 can
be preset such that a known number of turns or portions of a turn
(e.g., 1/2 turn, 1 turn, 10 turns, etc.) can result in a known
amount of advancement of the distal end portion 532 of the catheter
530. In some embodiments, the device 500 can be configured with a
mechanical advantage, gearing, etc. that can result in a "length
multiplying" and/or "displacement multiplying" effect such that a
relatively small amount of rotation of the actuator 550 results in
a relatively large amount of translation of the distal end portion
532 of the catheter 530. When accessing a vein or the like via the
PIV 505, the linear displacement of at least the distal end portion
532 of the catheter 530 can be sufficient to place a distal surface
of the catheter 530 in a desired position relative to a distal
surface of the PIV 505 regardless of the type and/or length of the
PIV 505. For example, in some instances, it may be desirable to
position the distal surface of the catheter 530 distal to the
distal surface of the PIV 505. In such instances, the arrangement
of the device 500 can be such that the housing 510 has a compact,
limited, and/or reduced length while the catheter 530 has a length
sufficient to extend beyond a distal end of the PIV 505.
[0092] While the arrangement of the actuator 550 and catheter 530
is described above as being used, for example, to multiply an
amount displacement of the distal end portion for a given angular
displacement of the actuator, in some embodiments, the arrangement
can also reduce an amount of force associated with advancing the
distal end portion 532 of the catheter 530. For example, in some
embodiments, the mechanical advantage, gearing, etc. can be such
that the distal end portion 532 of the catheter 530 is advanced in
response to a reduced amount of force being applied on the actuator
550. In some instances, reducing an amount of force associated with
advancement of the catheter 530 can reduce and/or limit damage to
the catheter 530 and/or other structure (e.g., a vein wall or
portion of the PIV 505) that may otherwise result from the distal
surface of the catheter 530 hitting an obstruction or the like.
[0093] While the housing 510 is shown in FIGS. 9 and 10 as
including the one or more internal structures 514 configured to
support, guide, and/or direct at least a portion of the catheter
530 as the catheter 530 is moved between the first position and the
second position, in other embodiments, a device can include a
housing having any suitable internal structure that can support,
guide, and/or direct at least a portion of a catheter. For example,
FIGS. 11-13 illustrate a fluid transfer device 600 according to
another embodiment. The fluid transfer device 600 (also referred to
herein as "device") can be any suitable shape, size, and/or
configuration. For example, at least a portion of the device 600
can be similar to and/or substantially the same as one or more
portions (and/or combination of portions) of the devices 100, 200,
300, 400, and/or 500 described above. Accordingly, portions of the
device 600 may not be described in further detail herein.
[0094] The device 600 includes a housing 610, a catheter 630, and
an actuator 650. The housing 610 includes and/or houses at least a
portion of the catheter 630 disposed, at least partially, in a
wound, looped, and/or coiled configuration. The housing 610
includes a first port 611 configured to fixedly receive a proximal
end portion 631 of the catheter 630 and a second port 612
configured to movably receive a distal end portion 632 of the
catheter 630. The ports 611 and 612 can be any suitable
configuration such as any of those described above.
[0095] As described above with reference to the housing 510, the
housing 610 can include one or more internal structures 614
configured to support, guide, and/or direct at least a portion of
the catheter 630 disposed in the housing 610. More particularly, in
the embodiment shown in FIGS. 11-13, the internal structure 614 can
be, for example, a cylindrical wall, drum, protrusion(s), ridge(s),
and/or the like. The internal structure 614 can be configured to
provide a structure and/or an axis about which at least a portion
of the catheter 630 can be wound, looped, and/or coiled, thereby
supporting at least the portion of the catheter 630 as the catheter
630 is moved between a first position and a second position, as
described in further detail herein.
[0096] The catheter 630 of the device 600 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 630 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, and/or 530 described above. Thus, such similar portions and/or
aspects of the catheter 630 may not described in further detail
herein. For example, in the embodiment shown in FIGS. 11-13, the
catheter 630 can be formed from any suitable material and can have
any suitable length, diameter, and/or configuration such as those
described above with reference to the catheter 130.
[0097] As described above, the catheter 630 or a portion thereof
can be moved (e.g., via rotational movement of the actuator 650)
between the first position (FIGS. 11 and 12), in which the distal
end portion 632 of the catheter 630 is disposed within the housing
610 and/or the second port 612, and a second position (FIG. 13), in
which at least a portion of the catheter 630 extends through the
second port 612 and at least a portion of an access device coupled
to the second port 612. In some embodiments, the catheter 630 can
have a length sufficient to place a distal surface of the catheter
630 a predetermined, desired, and/or at least a threshold distance
beyond a distal surface of the access device when the catheter 630
is in the second position, as described in detail above with
reference to the catheter 130.
[0098] The actuator 650 of the device 600 can be any suitable
shape, size, and/or configuration. For example, as shown in FIGS.
11-13, the actuator 650 includes a first portion 651 and a second
portion 652. The actuator 650 can be coupled to the housing 610 at
or near the second port 612 of the housing 610 (e.g., at or near a
distal end portion of the housing 610). In other embodiments, the
actuator 650 can be coupled to the housing 610 at any suitable
position along a length of the housing 610. The actuator 650 can be
coupled to the housing 610 in any suitable manner that allows the
actuator 650 to be rotated relative to the housing 610. Moreover,
the actuator 650 can be coupled to the housing 610 such that the
second portion 652 is at least partially disposed within the
housing 610 and in contact with and/or otherwise allowed to engage
the catheter 630. In this manner, the actuator 650 can be
substantially similar in at least form and/or function to the
actuator 250 described above with reference to FIGS. 3 and 4.
[0099] In use, the device 600 can be in a first configuration
and/or state in which the distal end portion of the catheter is 630
is disposed within the housing 610 and/or the second port 612
(FIGS. 11 and 12) and a user can manipulate the device 600 by
engaging the first portion 651 of the actuator 650 to place the
device 600 in a second configuration and/or state (FIG. 13). For
example, the user can exert a force on the first portion 651 of the
actuator 650 to rotate the actuator 650 in, for example, a
clockwise direction, as indicated by the arrow GG in FIG. 13. As
such, the second portion 652 of the actuator 650 rotates relative
to the housing 610 and engages the catheter 630 to move the
catheter 630 in the distal direction from the first position to the
second position, as indicated by the arrow HH in FIG. 13. Thus,
when the second port 612 of the housing 610 is coupled to an access
device or the like (not shown), the catheter 630 can be advanced to
a desired position relative to the access device, as described in
detail above with reference to the device 100. Moreover, in some
instances, the catheter 630 can be configured to transfer a volume
of fluid (e.g., bodily fluid, medicament, saline, etc.) through the
catheter 630 between the patient and a fluid source or fluid
reservoir connected to the proximal end portion 631 of the catheter
630 via a coupler 633 or the like. In some instances, once a
desired volume of fluid has been transferred through the catheter
630, the user can rotate the actuator 650, for example, in a
counterclockwise direction to retract and/or move the catheter 630
from the second position to the first position.
[0100] FIGS. 14 and 15 are schematic illustrations of a fluid
transfer device 700 in a first configuration and second
configuration, respectively, according to another embodiment. The
fluid transfer device 700 (also referred to herein as "device") can
be any suitable shape, size, and/or configuration. For example, at
least a portion of the device 700 can be similar to and/or
substantially the same as one or more portions (and/or combination
of portions) of the devices 100, 200, 300, 400, 500, and/or 600
described above. More specifically, the device 700 can be
substantially similar in at least form and/or function to the
device 500 described above with reference to FIGS. 9 and 10. Thus,
portions of the device 700 may not be described in further detail
herein.
[0101] The device 700 includes at least a housing 710, a catheter
730, and an actuator 750. The housing 710 can be any suitable
configuration. For example, in some embodiments, the housing 710
can have a substantially circular cross-sectional shape. In some
embodiments, the housing 710 can be substantially similar in form
and/or function to the housing 510 described above. For example,
the housing 710 includes a first port 711 and a second port 712.
The ports 711 and 712 can be any suitable configuration such as
those described above with reference to the first port 511 and the
second port 512, respectively. In the embodiment shown in FIGS. 14
and 15, the first port 711 is configured to fixedly receive and/or
couple to a proximal end portion 731 of the catheter 730. The
second port 712 is configured to movably receive a distal end
portion 732 of the catheter 730. Moreover, the second port 712 can
be a lock mechanism and/or coupler configured to couple the device
700 to an access device or the like such as, for example, a PIV 705
(e.g., an indwelling PIV), as described above.
[0102] The housing 710 can differ from the housing 510, however, in
the arrangement and/or placement of the first port 711. For
example, as shown in FIGS. 14 and 15, the first port 711 can be
disposed in a center or central portion of the housing 710. In
other embodiments, however, the first port 711 can be disposed at
any other suitable position along the housing 710. Moreover, the
housing 710 can be configured to receive at least a portion of the
actuator 750 such that the housing 710 and the portion of the
actuator 750 collectively define a channel 715 configured to
receive at least a portion of the catheter 730, as described in
further detail herein. While the channel 715 is shown in FIGS. 14
and 15 as being substantially circular and disposed adjacent to an
exterior wall of the housing 710, it should be understood that the
channel 715 can be any suitable shape, size, and/or
configuration.
[0103] The catheter 730 of the device 700 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 730 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, and/or 630 described above. Thus, such similar portions
and/or aspects of the catheter 730 may not described in further
detail herein. For example, in the embodiment shown in FIGS. 14 and
15, the catheter 730 can be formed from any suitable material and
can have any suitable length, diameter, and/or configuration such
as those described above with reference to the catheter 130.
[0104] At least a portion of the catheter 730 is movably disposed
within the housing 710. In some embodiments, the catheter 730 or a
portion thereof can be moved (e.g., via rotational movement of the
actuator 750) between a first position (FIG. 14), in which the
distal end portion 732 of the catheter 730 is disposed within the
housing 710 and/or the second port 712, and a second position (FIG.
15), in which at least a portion of the catheter 730 extends
through the second port 712 and at least a portion of an access
device coupled to the second port 712. In some embodiments, the
catheter 730 can have a length sufficient to place a distal surface
of the catheter 730 a predetermined, desired, and/or at least a
threshold distance beyond a distal surface of the access device
when the catheter 730 is in the second position, as described in
detail above. In some embodiments, at least a portion of the
catheter 730 can be disposed within the housing 710 and can engage
at least a portion of the actuator 750 in a manner similar to that
of the catheter 530 described in detail above. Thus, the
arrangement of the catheter 730 is not described in further detail
herein.
[0105] The actuator 750 of the device 700 can be any suitable
shape, size, and/or configuration. In the embodiment shown in FIGS.
14 and 15, the actuator 750 is movably coupled to the housing 710
and has a spool structure 754 that is movably coupled to the
housing 710. The spool structure 754 is at least partially disposed
within the housing 710 and is configured to define the channel 715
with a portion of the housing 710, as described above. Moreover,
the spool structure 754 is coupled to at least a portion of the
catheter 730 (e.g., the proximal end portion 731 of the catheter
730). Although not shown in FIGS. 14 and 15, in some embodiments
the spool structure 754 can include a portion disposed outside of
the housing 710 and configured to be engaged by a user to rotate
the spool structure 754 (and/or the actuator 750) relative to the
housing 710. Accordingly, the actuator 750 can be substantially
similar in at least form and/or function to the actuator 550
described in detail above with reference to FIGS. 9 and 10. Thus,
the actuator 750 is not described in further detail herein.
[0106] In some embodiments, the catheter 730 is disposed within the
channel 715 and wound around the spool structure 754 of the
actuator 750. As such, a rotational movement of the actuator 750
results in a rotational movement of at least a portion of the
catheter 730 that is wound or coiled around the spool structure
754. Such an arrangement, in turn, results in a spooling (or
unspooling), coiling (or uncoiling), winding (or unwinding), etc.
of at least a portion of the catheter 730, thereby moving and/or
transitioning the catheter 730 between the first position and the
second position. In some implementations, the distal end portion
732 of the catheter 730 can be at least partially disposed within
and/or otherwise aligned with the second port 712 such that the
rotation of the actuator 750 and the portion of the catheter 730
results in a substantially linear movement of the distal end
portion 732 of the catheter 730 relative to, within, and/or through
the second port 712.
[0107] In use, the device 700 can be in a first configuration or
state (FIG. 14) and the user can engage and/or manipulate the
device 700 by rotating the actuator 750, thereby transitioning the
device from the first configuration or state to the second
configuration or state (FIG. 15). More specifically, user can
rotate the actuator 750 (and thus, the spool structure 754) in a
clockwise direction, as indicated by the arrows II in FIG. 15. The
rotation of the actuator 750 moves the catheter 730 from the first
position and the second position. With the proximal end portion 731
of the catheter 730 fixedly coupled to the first port 711 and the
distal end portion 732 of the catheter 730 configured to move
relative to the housing 710, rotating the actuator 750, for
example, advances a portion of the catheter 730 along and/or
through the channel 715, which in turn, moves the distal end
portion 732 of the catheter 730 relative to the second port 712
and/or the access device coupled thereto, as indicated by the arrow
JJ in FIG. 15. Thus, the device 700 can be substantially similar in
at least form and/or function to the device 500 described in detail
above.
[0108] While the device 700 shown in FIGS. 14 and 15 is described
as being actuated and/or used by turning the actuator 750, and more
specifically, the spool structure 754, in other embodiments, a
device can include any number of actuators and/or actuator portions
which can collectively act to move and/or transition the catheter
730 between the first position and the second position. For
example, FIGS. 16 and 17 illustrate a fluid transfer device 800
according to another embodiment in a first configuration and a
second configuration, respectively. In this embodiment, the device
800 can be substantially similar in structure and/or function to
the device 700 except for the inclusion of one or more additional
actuators and/or actuator portions.
[0109] The fluid transfer device 800 (also referred to herein as
"device") can be any suitable shape, size, and/or configuration.
For example, at least a portion of the device 800 can be similar to
and/or substantially the same as one or more portions (and/or
combination of portions) of the devices 100, 200, 300, 400, 500,
600, and/or 700 described above. For example, as described in
further detail herein, the device 800 can be a combination of
certain portions and/or aspects of the devices 200 and 700. Thus,
portions of the device 800 may not be described in further detail
herein.
[0110] The device 800 includes at least a housing 810, a catheter
830, and an actuator 850. The housing 810 can be any suitable
configuration. For example, in some embodiments, the housing 810
can have a substantially circular cross-sectional shape. In some
embodiments, the housing 810 can be substantially similar in form
and/or function to the housing 710 described above. For example,
the housing 810 includes a first port 811 configured to be fixedly
coupled to a proximal end portion 831 of the catheter 830 and a
second port 812 configured to receive a distal end portion 832 of
the catheter 830, as described above with reference to the device
700. Thus, the housing 810 and/or aspects thereof are not described
in further detail herein.
[0111] The catheter 830 of the device 800 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 830 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, and/or 730 described above. Thus, such similar
portions and/or aspects of the catheter 830 may not described in
further detail herein. For example, in the embodiment shown in
FIGS. 16 and 17, the catheter 630 can be formed from any suitable
material and can have any suitable length, diameter, and/or
configuration such as those described above with reference to the
catheter 130.
[0112] At least a portion of the catheter 830 is movably disposed
within the housing 810. In some embodiments, the catheter 830 or a
portion thereof can be moved (e.g., via rotational movement of the
actuator 850) between a first position (FIG. 16), in which the
distal end portion 832 of the catheter 830 is disposed within the
housing 810 and/or the second port 812, and a second position (FIG.
17), in which at least a portion of the catheter 830 extends
through the second port 812 and at least a portion of an access
device coupled to the second port 812. In some embodiments, the
catheter 830 can have a length sufficient to place a distal surface
of the catheter 830 a predetermined, desired, and/or at least a
threshold distance beyond a distal surface of the access device
when the catheter 830 is in the second position, as described in
detail above. In some embodiments, at least a portion of the
catheter 830 can be disposed within the housing 810 and can engage
at least a portion of the actuator 850 in a manner similar to that
of the catheter 730 described in detail above. Thus, the
arrangement of the catheter 830 is not described in further detail
herein.
[0113] The actuator 850 of the device 800 can be any suitable
shape, size, and/or configuration. In the embodiment shown in FIGS.
16 and 17, the actuator 850 is movably coupled to the housing 810
and has a spool structure 854 that is movably coupled to the
housing 810. The spool structure 854 is at least partially disposed
within the housing 810 and is configured to define a channel 815
with a portion of the housing 810. Moreover, the spool structure
854 is coupled to at least a portion of the catheter 830 (e.g., the
proximal end portion 831 of the catheter 830). In this manner, the
spool structure 854 can be substantially similar to the spool
structure 754 described above with reference to FIGS. 14 and
15.
[0114] The actuator 850 can differ from the actuator 750, however,
by including a second actuator 850A. The second actuator 850A
includes a first portion 851 and a second portion 852. In the
embodiment shown in FIGS. 16 and 17, the second actuator 850 can be
used to move or transition the catheter 830 between the first
position and the second position. The second actuator 850A can be
coupled to the housing 810 at or near the second port 812 of the
housing 810 (e.g., at or near a distal end portion of the housing
810). The second actuator 850A can be coupled to the housing 810 in
any suitable manner that allows the second actuator 850A to be
rotated relative to the housing 810. Moreover, the second portion
852 of the second actuator 850A is at least partially disposed
within the housing 810 and in contact with and/or otherwise allowed
to engage the catheter 830. In this manner, the second actuator
850A can be substantially similar in at least form and/or function
to the actuator 250 described above with reference to FIGS. 3 and
4.
[0115] In use, the second actuator 850A can be rotated relative to
the housing 810 to advance the catheter 830 from the first position
to the second position. The rotation of the first portion 851 of
the actuator 850 in the clockwise direction (indicated by the arrow
KK in FIG. 17) advances the portion of the catheter 850 engaged
with the second portion 852 of the actuator 850 (e.g., in response
to a friction force therebetween). The advancement of the portion
of the catheter 850 in turn results in a tugging force of the
portion of the catheter 850 disposed within the portion of the
channel 815 defined by the spool structure 854 and the housing 810.
As such, the spool structure 854 is similarly rotated in the
clockwise direction, thereby resulting in a gradual release of the
portion of the catheter 850 disposed in the portion of the channel
815. Accordingly, actuating and/or rotating the second actuator
850A advances at least the distal end portion 832 of the catheter
830 in or along a linear path through the second port 812 of the
housing 810, as indicated by the arrow LL in FIG. 17.
[0116] While the catheter 830 is shown in FIGS. 16 and 17 as being
at least partially spooled or wound around the spool structure 854
(e.g., around an exterior of the spool structure 854), in other
embodiments, a device can include an actuator that has a spool
structure configured to engage a catheter in any suitable manner.
For example, FIGS. 18-20 illustrate a device 900 according to
another embodiment. The fluid transfer device 900 (also referred to
herein as "device") can be any suitable shape, size, and/or
configuration. For example, at least a portion of the device 900
can be similar to and/or substantially the same as one or more
portions (and/or combination of portions) of the devices 100, 200,
300, 400, 500, 600, 700, and/or 800 described above. Thus, portions
of the device 900 may not be described in further detail
herein.
[0117] The device 900 includes at least a housing 910, a catheter
930, and an actuator 950. The housing 910 can be any suitable
configuration. For example, in some embodiments, the housing 910
can have a substantially circular cross-sectional shape. In some
embodiments, the housing 910 can be substantially similar in at
least form and/or function to the housings 710 and/or 810 described
above. For example, the housing 910 includes a first port 911
configured to be coupled to and/or to otherwise receive a proximal
end portion 931 of the catheter 930 and a second port 912
configured to receive a distal end portion 932 of the catheter 930.
In some embodiments, the first port 911 can be configured to
fixedly couple to the proximal end portion 931 of the catheter 930,
as described above with reference to the devices 700 and/or 800.
Thus, the housing 910 and/or aspects thereof are not described in
further detail herein.
[0118] The catheter 930 of the device 900 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 930 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, 730, and/or 830 described above. Thus, such similar
portions and/or aspects of the catheter 930 may not described in
further detail herein. For example, in the embodiment shown in
FIGS. 18-20, the catheter 930 can be formed from any suitable
material and can have any suitable length, diameter, and/or
configuration such as those described above with reference to the
catheter 130.
[0119] At least a portion of the catheter 930 is movably disposed
within the housing 910. In some embodiments, the catheter 930 or a
portion thereof can be moved (e.g., via rotational movement of the
actuator 950) between a first position (FIG. 18), in which the
distal end portion 932 of the catheter 930 is disposed within the
housing 910 and/or the second port 912, and a second position (FIG.
20), in which at least a portion of the catheter 930 extends
through the second port 912 and at least a portion of an access
device (not shown) coupled to the second port 912. In some
embodiments, the catheter 930 can have a length sufficient to place
a distal surface of the catheter 930 a predetermined, desired,
and/or at least a threshold distance beyond a distal surface of the
access device when the catheter 930 is in the second position, as
described in detail above. In some embodiments, at least a portion
of the catheter 930 can be disposed within the housing 910 and can
engage at least a portion of the actuator 950, as described in
further detail herein.
[0120] The actuator 950 of the device 900 can be any suitable
shape, size, and/or configuration. In the embodiment shown in FIGS.
18-20, the actuator 950 has a spool structure 954 that is movably
coupled to the housing 910. The spool structure 954 can be coupled
to, can receive, and/or otherwise can engage at least a portion of
the catheter 930 (e.g., the proximal end portion 931 of the
catheter 930) to move the catheter 930 between a first position and
a second position, as described in further detail herein. As shown,
for example, in FIG. 18, the spool structure 954 is at least
partially disposed within the housing 910 such that the spool
structure 954 and the housing 910 collectively define an outer
channel 915. More specifically, the spool structure 954 can be
sized and positioned within the housing 910 such that an exterior
or outer portion and/or surface of the spool structure 954 is
spaced apart from an interior or inner portion and/or surface of
the housing 910 (e.g., an inner perimeter). The space, in turn,
forms and/or defines the outer channel 915, which is configured to
receive at least a portion of the catheter 930, as described in
further detail herein.
[0121] The spool structure 954 includes a set of engagement
structures 957 configured to selectively engage a portion of the
catheter 930 within the housing 930. More specifically, in the
embodiment shown in FIGS. 18-20, the set of engagement structures
957 includes a pair of engagement structures 957 that can have any
suitable size, shape, and/or configuration. For example, the
engagement structures 957 can have substantially the same size
and/or shape such as, for example, a teardrop-shape, as shown in
FIGS. 18-20. The engagement structures 957 can be disposed in a
mirrored arrangement relative to each other such that the spool
structure 954 defines an inner channel 958 or pathway between the
pair of engagement structures 957 that is configured to movably
receive a portion of the catheter 930. The inner channel 958 can
be, for example, a serpentine, circuitous, tortuous, and/or
otherwise curved or non-linear channel or pathway that at least
partially corresponds to a size and/or shape of a portion of the
engagement structures 957.
[0122] The catheter 930 is disposed within the housing 910 such
that a portion of the catheter 930 is disposed within at least one
of the outer channel 915 and/or the inner channel 958 and is
configured to be advanced therethrough (e.g., through the housing
910) in response to actuation of the actuator 950. For example,
FIG. 18 illustrates the device 900 in a first configuration and/or
state in which the catheter 930 is in the first position. As shown,
when the catheter 930 is in the first position, a portion of the
catheter 930 can extend from the first port 911, through at least a
portion of the outer channel 915, through the inner channel 958,
and at least partially into the second port 912. As shown in FIGS.
18-20, rotating the spool structure 954 rotates the engagement
structures 957 (and the inner channel 958) relative to the first
port 911 and the second port 912 of the housing 910.
[0123] As shown in FIG. 18, the arrangement of the catheter 930
when the device 900 is in the first configuration and/or state is
such the proximal end portion 931 of the catheter 930 extends from
the first port 911 and is disposed within and/or passes through a
first portion the outer channel 915, a medial portion of the
catheter 930 is disposed within and passes through the inner
channel 958, and a third portion of the catheter 930 is disposed
within and passes through a second portion of the outer channel 915
such that the distal end portion 932 of the catheter 930 is at
least partially disposed within the second port 912 of the housing
910. As such, while the inner channel 958 is at least partially
aligned with at least one of the first port 911 and/or the second
port 912, the catheter 930 passes around one of the engagement
structures 957 prior to entering and/or being disposed within the
inner channel 958. In this position and/or orientation, the path
through which the catheter 930 extends between the first port 911
and the second port 912 is, for example, the longest or
substantially the longest path between the first port 911 and the
second port 912. Thus, the largest or substantially the largest
portion of the catheter 930 is disposed within the housing 910 when
the device 900 is in the first configuration and/or state (e.g.,
when the catheter 930 is in the first position).
[0124] As shown in FIG. 19, the device 900 can be transitioned from
the first configuration and/or state by rotating the actuator 950
in a counterclockwise direction, as indicated by the arrow MM in
FIG. 19. The rotation of the actuator 950 results in a rotation of
the engagement structures 957, which in turn, changes a portion of
the outer channel 915 that is disposed between the first port 911
and a first end portion of the inner channel 958 and a portion of
the outer channel 915 that is disposed between the second port 912
and a second end portion of the inner channel 958 opposite the
first end portion. More specifically, the portions of the outer
channel 915 are reduced, which in turn, is operable to advance the
catheter 930 through a serpentine, circuitous, tortuous, and/or
otherwise curved or non-linear path collectively formed and/or
defined by the outer channel 915 and the inner channel 958 from its
first position toward its second position.
[0125] As shown in FIG. 20, the actuator 950 can be actuated (e.g.,
rotated) a predetermined and/or desired amount to place the device
900 in a second configuration and/or state in which the catheter
930 is in the second position. More specifically, in some
implementations, the device 900 can be in the second configuration
and/or state when rotation of the actuator 950 results in the end
portions of the inner channel 958 being at least partially aligned
with the first port 911 or the second port 912. In this position
and/or orientation, the inner channel 958 can define, for example,
the shortest path through the housing 910 between the first port
911 and the second port 912. As shown, the catheter 930 extends
along the path when the device 900 is in the second configuration
and/or state such that the smallest or substantially the smallest
portion of the catheter is disposed in the housing 910. As
described in detail above with reference to previous embodiments,
the arrangement of the device 900 can allow the catheter 930 to
have a length or "reach" that can be longer than, for example, the
housing 910 and/or a length of the housing 910 between the first
port 911 and the second port 912. Thus, when the second port 912 of
the housing 910 is coupled to an access device or the like (not
shown), the catheter 930 can be advanced to a desired position
relative to the access device regardless of a type and/or length of
the access device, as described in detail above with reference to
the device 100.
[0126] FIGS. 21-23 illustrate a fluid transfer device 1000
according to another embodiment. The fluid transfer device 1000
(also referred to herein as "device") can be similar to and/or
substantially the same as the device 900 described above with
reference to FIGS. 18-20. Accordingly, while portions and/or
aspects of the device 1000 are identified below such portions
and/or aspects may not be described in further detail.
[0127] As shown, the device 1000 includes a housing 1010, a
catheter 1030, and an actuator 1050. The housing 1010 can be
substantially similar to the housing 910 described in detail above.
For example, the housing 1010 includes a first port 1011 that can
be fixedly coupled to a proximal end portion 1031 of the catheter
1030 and includes a second port 1012 that can movably receive a
distal end portion 1032 of the catheter 1030. The catheter 1030 can
be substantially similar to the catheter 930 described in detail
above. For example, as shown in FIG. 23, the catheter 1030 is at
least partially disposed within the housing 1010 and is configured
to be engaged by at least a portion of the actuator 1050 and/or is
configured to be disposed within a space, one or more channels, one
or more lumens, one or more volumes, etc. defined by the housing
1010, the actuator 1050, and/or collectively defined by the housing
1010 and actuator 1050, as described in further detail herein.
[0128] In some embodiments the catheter 1030 can be formed of a
single material and can have a predetermined length, diameter,
and/or configuration such as those described above with respect to
the catheter 130. In other embodiments, the catheter 1030 can be
formed of different materials and/or can have different size,
shape, diameter, thickness, etc. to result in any suitable
stiffness, flexibility, hardness, and/or durometer. For example,
the proximal end portion 1031 of the catheter 1030 can be formed
from a relatively flexible material which can deform in response to
a sudden change in pressure reducing the likelihood of collapsing
the catheter 1030 at a location downstream to the proximal end
portion. The distal end portion of the catheter 1032 can be formed
from a relatively rigid material or a material having a stiffness
and/or rigidity that is at least greater than stiffness and/or
rigidity of the proximal end portion 1031 and can have a diameter
smaller than that of the proximal end portion 1031 to facilitate
advancing the catheter 1030 to and from a desired position relative
to a PIV. In some embodiments, the proximal end portion 1031 and
the distal end portion 1032 of the catheter 1030 can be separate
components having a different length, diameter, stiffness,
flexibility, material, and/or configuration, which can be
mechanically and fluidically connected using adapter 1034 located
within the first port 1011, as shown in FIGS. 21-23.
[0129] The actuator 1050 can be substantially similar to the
actuator 950 described in detail above. For example, the actuator
1050 includes a spool structure 1054 having a pair of engagement
structures 1057 that are disposed in a mirrored orientation
relative to each other such that an inner channel 1058 or path is
defined therebetween. In some embodiments, the actuator 1050 can
include a tube, introducer, sheath, and/or the like disposed within
the inner channel 1058 and configured to support and guide the
catheter 1030, limiting and/or substantially preventing undesired
deformation and/or deflection of a portion of the catheter 1030 as
the device is transitioned between a first configuration to a
second configuration. In some embodiments, one or more surfaces of
the actuator 1050 and/or spool structure 1054 can selectively
contact and/or otherwise support the catheter 1030 as a portion of
the catheter is moved through the housing.
[0130] As described above with reference to the device 900, the
device 1000 is configured to be transitioned from a first
configuration and/or state (FIG. 21) in response to rotation of the
actuator 1050, as indicated by the arrow NN. The catheter 1030 is
configured to be in a first position when the device 1000 is in the
first configuration and/or state such that a largest or
substantially the largest portion or length of the catheter 1030 is
disposed within the housing 1010 between the first port 1011 and
the second port 1012.
[0131] In some instances, the user can rotate the actuator 1050 to
place the device 1000 in a second configuration and/or state (FIG.
22). The catheter 1030 is configured to be in a second position
when the device 1000 is in the second configuration and/or state
such that a smallest or substantially the smallest portion or
length of the catheter 1030 is disposed within the housing 1010
between the first port 1011 and the second port 1012. Moreover, as
described in detail above, the distal end portion 1032 of the
catheter 1030 can be placed in a desired position (e.g., a distal
position) relatively to the second port 1012 and/or an access
device coupled to the second port 1012 when the catheter 1030 is in
the second position.
[0132] While the engagement structures 957 and/or 1057 are shown
and described above as being substantially the same size, shape,
and/or configuration and arranged in a mirrored orientation
relative to each other, in other embodiments, a spool structure can
include a set of engagement structures in which each engagement
structure can have any suitable shape, size, and/or configuration.
For example, FIGS. 24 and 25 a fluid transfer device 1100 according
to another embodiment. The fluid transfer device 1100 (also
referred to herein as "device") can be any suitable shape, size,
and/or configuration. For example, at least a portion of the device
1100 can be similar to and/or substantially the same as one or more
portions (and/or combination of portions) of the devices 100, 200,
300, 400, 500, 600, 700, 800, 900, and/or 1000 (or any suitable
combinations thereof) described above. Thus, portions of the device
1100 may not be described in further detail herein.
[0133] The device 1100 includes at least a housing 1110, a catheter
1130, and an actuator 1150. The housing 1110 can be any suitable
configuration. For example, in some embodiments, the housing 1110
can have a substantially circular cross-sectional shape. In some
embodiments, the housing 1110 can be substantially similar in at
least form and/or function to the housings 910 and/or 1010
described above. For example, the housing 1110 includes a first
port 1111 configured to be coupled to and/or to otherwise receive a
proximal end portion 1131 of the catheter 1130 and a second port
1112 configured to receive a distal end portion 1132 of the
catheter 1130. In some embodiments, the first port 1111 can be
configured to fixedly couple to the proximal end portion 1131 of
the catheter 1130, as described above with reference to the device
900. Thus, the housing 1110 and/or aspects thereof are not
described in further detail herein.
[0134] The catheter 1130 of the device 1100 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 1130 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, 730, 830, 930, and/or 1030 described above. Thus,
such similar portions and/or aspects of the catheter 1130 may not
described in further detail herein. For example, in the embodiment
shown in FIGS. 24 and 25, the catheter 1130 can be formed from any
suitable material and can have any suitable length, diameter,
and/or configuration such as those described above with reference
to the catheter 130.
[0135] At least a portion of the catheter 1130 is movably disposed
within the housing 1110. In some embodiments, the catheter 1130 or
a portion thereof can be moved (e.g., via rotational movement of
the actuator 1150) between a first position (FIG. 24), in which the
distal end portion 1132 of the catheter 1130 is disposed within the
housing 1110 and/or the second port 1112, and a second position
(FIG. 25), in which at least a portion of the catheter 1130 extends
through the second port 1112 and at least a portion of an access
device (not shown) coupled to the second port 1112. In some
embodiments, the catheter 1130 can have a length sufficient to
place a distal surface of the catheter 1130 a predetermined,
desired, and/or at least a threshold distance beyond a distal
surface of the access device when the catheter 1130 is in the
second position, as described in detail above.
[0136] The actuator 1150 of the device 1100 can be any suitable
shape, size, and/or configuration. In some embodiments, the
actuator 1150 can be substantially similar in at least form and/or
function to the actuator 950 described in detail above. For
example, in the embodiment shown in FIGS. 24 and 25, the actuator
1150 has a spool structure 1154 that is movably coupled to the
housing 1110. The spool structure 1154 includes a first engagement
structure 1157A and a second engagement structure 1157B configured
to selectively engage a portion of the catheter 1130 within the
housing 1110. As described above with reference to the actuator
950, the spool structure 1154 can be at least partially disposed
within the housing 1110 such that the spool structure 1154 and the
housing 1110 collectively define an outer channel 1115. The spool
structure 1154 can be configured to guide, direct, and/or engage at
least a portion of the catheter 1130 that is disposed within the
housing 1110, as described in further detail herein. Moreover, the
catheter 1130 can be spooled, wound, and/or wrapped around the
spool structure 1154 in a manner substantially similar to the
manner in which the catheter 930 is spooled, wound, and/or wrapped
around the spool structure 954. Accordingly, rotation of the
actuator 1150 in a counterclockwise direction (indicated as arrow
OO in FIG. 24) is operable to move the catheter 1130 from the first
position (FIG. 24) to the second position (FIG. 25).
[0137] While the engagement structures 957 and 1057 are described
above as being substantially the same shape, size, and/or
configuration, in the embodiment shown in FIGS. 24 and 25, the
engagement structures 1157A and 1157B are different shapes, sizes,
and/or configurations. For example, the arrangement of the spool
structure 1154 is such that the first engagement structure 1157A is
larger than the second engagement structure 1157B. The engagement
structures 1157 can be disposed in a mirrored arrangement relative
to each other such that the spool structure 1154 defines an inner
channel 1158 or pathway between the engagement structures 1157A and
1157B that is configured to movably receive a portion of the
catheter 1130.
[0138] In some embodiments, the size and/or shape of the engagement
structures 1157A and 1157B, and thus, the position of the inner
channel 1158 can be based at least in part on a location or
position of at least one of the first port 1111 or the second port
1112 of the housing 1110. For example, as shown in FIGS. 24 and 25,
a size of at least the second engagement portion 1158 can be based
at least in a part on and/or can substantially correspond to a
distance between the first port 1111 and the second port 1112. In
some embodiments, the size and/or shape of the engagement
structures 1157A and/or 1157B can be such that each end portion of
the inner channel 1158 is substantially aligned with at least one
of the first port 1111 or the second port 1112 when the device 1100
is in each of the first configuration and/or state and the second
configuration and/or state, as shown in FIGS. 24 and 25,
respectively. In some embodiments, increasing or decreasing the
size or shape of the engagement structures 1157A and 1157B can, for
example, increase or decrease, respectively, a length or "reach" of
the catheter 1130. For example, a path at least partially defined
by the inner channel 1158 between the first port 1111 and the
second port 1112 of the housing 1110 can be shorter than the path
at least partially defined by the inner channel 958 between the
first port 911 and the second port 912. Accordingly, one means of
tuning a length and/or reach of a catheter can be increasing and/or
decreasing a size and/or shape of the engagement structures.
[0139] FIG. 26 illustrates a fluid transfer device 1200 according
to another embodiment. The fluid transfer device 1200 (also
referred to herein as "device") can be any suitable shape, size,
and/or configuration. For example, at least a portion of the device
1200 can be similar to and/or substantially the same as one or more
portions (and/or combination of portions) of the devices 100, 200,
300, 400, 500, 600, 700, 800, 900, 1000, and/or 1100 (or any
suitable combinations thereof) described above. More specifically,
at the device 1200 can be substantially similar in at least form
and/or function to the device 900, 1000, and/or 1100 described in
detail above. Thus, portions of the device 1200 may not be
described in further detail herein.
[0140] The device 1200 can differ from the device 900, however, in
that the device 1200 is, for example, two devices coupled together
with a single catheter passing therethrough. As shown, the device
1200 includes at least a housing 1210, a catheter 1230, a first
actuator 1250A and a second actuator 1250B. The housing 1210 can be
any suitable configuration. In some embodiments, the housing 1210
and/or portions thereof can be substantially similar in at least
form and/or function to the housings 910, 1010, and/or 1110
described above. The housing 1210 can differ from the housings 910,
1010, and/or 1110 in that the housing 1210 is, for example, two
housings coupled together. For example, the housing 1210 can
include a first portion configured to receive the first actuator
1250A and a second portion configured to receive the second
actuator 1250B. The first portion of the housing 1210 includes
and/or is coupled to a first port 1211 that can be fixedly coupled
to a proximal end portion 1231 of the catheter 1230. The second
portion of the housing 1210 includes and/or is coupled to a second
port 1212 that can movably receive a distal end portion 1232 of the
catheter 1230. Accordingly, a portion of the catheter 1230 is
configured to be disposed within the first and second portions of
the housing 1210 (e.g., along a path inside the housing 1210
defined between the first port 1211 and the second port 1212).
[0141] The catheter 1230 of the device 1200 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 1230 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, 730, 830, 930, 1030, and/or 1130 described above. As
shown in FIG. 26, the catheter 1230 is at least partially disposed
within the housing 1210 and is configured to engage or be engaged
by at least a portion of the one or more actuators. For example, in
some embodiments, the form and/or arrangement of the catheter 1230
within the housing 1210 can be substantially similar to the form
and/or arrangement to the catheter 930 described in detail
above.
[0142] The first actuator 1250A is disposed within the first
portion of the housing 1210 and includes a set of engagement
structures 1257A. More specifically, the first actuator 1250A
includes a pair of engagement structures 1257A that are disposed in
a mirrored orientation relative to each other such that a first
inner channel 1258A or path is defined there between, as described
in detail above with reference to the actuator 950. In the
embodiment shown in FIG. 26, the engagement structures 1257A can
have, for example, a hemispherical shape. In other embodiments, the
engagement structures can be any suitable shape and/or size such
as, for example, teardrop-shaped and/or any other suitable shape.
The second actuator 1250B is disposed with in the second portion of
the housing 1210 and includes a set of engagement structures 1257B.
The engagement structures 1257B can be substantially similar in
shape, size, and/or configuration to the engagement structures
1257A. Accordingly, the engagement structures 1257B define a second
inner channel 1258B therebetween.
[0143] As described above with reference to the devices 900, 1000,
and/or 1100, the device 1200 is configured to be transitioned from
a first configuration and/or state to a second configuration and/or
state in response to rotation of the actuator 1250, as indicated by
the arrow PP. The catheter 1230 is configured to be in a first
position when the device 1200 is in the first configuration and/or
state such that a largest or substantially the largest portion or
length of the catheter 1230 is disposed within the housing 1210
between the first port 1211 and the second port 1212 (e.g., within
one or more lumen (e.g., an outer channel or portion thereof)
defined by the housing 1210 and/or the inner channels 1258A and
1258B). The catheter 1230 is configured to be in a second position
when the device 1200 is in the second configuration and/or state
such that a smallest or substantially the smallest portion or
length of the catheter 1230 is disposed within the housing 1210
between the first port 1211 and the second port 1212. Although not
shown, in the embodiment shown in FIG. 26, the device 1200 can be
configured such that the catheter 1230 extends along a
substantially straight path at least partially defined by the inner
channels 1258A and 1258B between the first port 1211 and the second
port 1212 when the device 1200 is in the second configuration
and/or state. Moreover, as described in detail above, the distal
end portion 1232 of the catheter 1230 can be placed in a desired
position (e.g., a distal position) relatively to the second port
1212 and/or an access device coupled to the second port 1212 when
the catheter 1230 is in the second position. In some
implementations, the arrangement and/or configuration of the device
1200 can allow the catheter 1230 to have an increased length
relative to, for example, the catheter lengths of the devices 900,
1000, and/or 1100.
[0144] FIG. 27 illustrates a fluid transfer device 1300 according
to another embodiment. The fluid transfer device 1300 (also
referred to herein as "device") can be any suitable shape, size,
and/or configuration. For example, at least a portion of the device
1300 can be similar to and/or substantially the same as one or more
portions (and/or combination of portions) of the devices 100, 200,
300, 400, 500, 600, 700, 800, 900, 1000, 1100, and/or 1200
described above. More specifically, the device 1300 can be
substantially similar in at least form and/or function to the
devices 900, 1000, 1100, and/or 1200 (or any suitable combinations
thereof) described in detail above. Thus, portions of the device
1300 may not be described in further detail herein.
[0145] As shown, the device 1300 includes at least a housing 1310,
a catheter 1330, and an actuator 1350. The housing 1310 can be any
suitable configuration. In some embodiments, the housing 1310
and/or portions thereof can be substantially similar in at least
form and/or function to the housings 910, 1010, and/or 1110
described above. For example, the housing 1310 includes a first
port 1311 configured to fixedly receive a proximal end portion 1331
of the catheter 1330 and a second port 1312 configured to receive a
distal end portion 1332 of the catheter 1330. Thus, portions and/or
aspects of the housing 1310 may not described in further detail
herein.
[0146] The catheter 1330 of the device 1300 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 1330 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, 730, 830, 930, 1030, 1130, and/or 1230 described
above. As shown in FIG. 27, the catheter 1330 is at least partially
disposed within the housing 1310 and is configured to engage or be
engaged by at least a portion of the actuator 1350. For example, in
some embodiments, the form and/or arrangement of the catheter 1330
within the housing 1310 can be substantially similar to the form
and/or arrangement to the catheter 930 described in detail
above.
[0147] The actuator 1350 of the device 1300 can be any suitable
shape, size, and/or configuration. In some embodiments, the
actuator 1350 can be substantially similar in at least form and/or
function to the actuators 950, 1050, 1150, and/or 1250 described in
detail above. The actuator 1350 can differ from the actuators 950,
1050, 1150, and/or 1250, however, by including a first spool
structure 1354A and a second spool structure 1354B. Each of the
spool structures 1354A and 1354B includes a pair of engagement
structures 1357A and 1357B, respectively. The engagement structures
1357A and 1357B can be any suitable shape, size, and/or
configuration. Moreover, the engagement structures 1357A
collectively define at least a portion of a first inner channel
1358A and the engagement structures 1357B collectively define at
least a portion of a second inner channel 1358B, as described above
with reference to the devices 900, 100, 1100, and/or 1200.
[0148] As shown in FIG. 27, the spool structures 1354A and 1354B
are configured to be disposed in the housing 1310 in a concentric
arrangement. For example, the first spool structure 1354A can be
disposed in the housing 1310 such that an outer channel 1315 is
collectively defined by an outer surface of the first spool
structure 1354A and an inner surface of the housing 1310, as
described above with reference to the device 900. The second spool
structure 1354B is at least partially disposed within the first
spool structure 1354A (e.g., between the pair of engagement
structures 1357A). Moreover, the arrangement of the second spool
structure 1354B within the first spool structure 1357A is such that
at least a portion of the first inner channel 1358A is collectively
defined by an inner surface of the engagement structures 1357A of
the first spool structure 1354A and an outer surface of the
engagement structures 1357B of the second spool structure
1354B.
[0149] As described above with reference to the actuator 950, the
spool structure 1354A and 1354B can be at least partially disposed
within the housing 1310 and configured to guide, direct, and/or
engage at least a portion of the catheter 1330 that is disposed
within the housing 1310. For example, the catheter 1330 can be
spooled, wound, and/or wrapped around the spool structure 1354A and
1354B such that when the catheter 1330 is in a first configuration
and/or position, a portion of the catheter 1330 extends from the
first port 1311 of the housing 1310, through at least a first
portion of the outer channel 1315, through the first inner channel
1358A and the second inner channel 1358B, through at least a second
portion of the outer channel 1315, and into the second port 1312.
In this manner, the catheter 1330 can be spooled, wound, and/or
wrapped around the spool structure 1354 in a similar manner as
described above with reference to the catheter 930 and spool
structure 954 (e.g., minus the second inner channel 1358B).
[0150] As described above with reference to the devices 900, 1000,
1100, and/or 1200, the device 1300 is configured to be transitioned
from a first configuration and/or state to a second configuration
and/or state in response to rotation of the actuator 1350. For
example, in some implementations, a user can rotate the actuator in
a counterclockwise direction, which in turn, rotates the first
spool structure 1354A in the counterclockwise direction, as
indicated by the arrow QQ in FIG. 27. The arrangement of the spool
structures 1354A and 1354B and/or the arrangement of the catheter
1330 passing through the inner channels 1358A and 1358B can be such
that the counterclockwise rotation of the first spool structure
1354A results in a rotation of the second spool structure 1354B in
a clockwise direction, as indicated by the arrow RR in FIG. 27. The
catheter 1330 is configured to be in a first position when the
device 1300 is in the first configuration and/or state such that a
larger or substantially the largest portion or length of the
catheter 1330 is disposed within the housing 1310 between the first
port 1311 and the second port 1312 (e.g., within one or more lumen
or channel defined by the housing 1310 and/or the inner channels
1358A and 1358B). The catheter 1330 is configured to be in a second
position when the device 1300 is in the second configuration and/or
state such that a smallest or substantially the smallest portion or
length of the catheter 1330 is disposed within the housing 1310
between the first port 1311 and the second port 1312. Although not
shown, in the embodiment shown in FIG. 27, the device 1300 can be
configured such that the catheter 1330 extends along a
substantially straight path at least partially defined by the inner
channels 1358A and 1358B between the first port 1311 and the second
port 1312 when the device 1300 is in the second configuration
and/or state. Moreover, as described in detail above, the distal
end portion 1332 of the catheter 1330 can be placed in a desired
position (e.g., a distal position) relatively to the second port
1312 and/or an access device coupled to the second port 1312 when
the catheter 1330 is in the second position. In some
implementations, the arrangement and/or configuration of the device
1300 can allow the catheter 1330 to have an increased length
relative to, for example, the catheter lengths of at least the
devices 900, 1000, and/or 1100.
[0151] While the portion of the catheter 1330 is shown in FIG. 27
as being wound, looped, and/or coiled around and/or through the
spool structures 1354A and 1354B of the actuator 1350, in other
embodiments, a device can include a catheter configured to be at
least partially disposed in a housing of the device in any suitable
configuration. For example, FIGS. 28-30 illustrate a device 1400
according to another embodiment. The fluid transfer device 1400
(also referred to herein as "device") can be any suitable shape,
size, and/or configuration. For example, at least a portion of the
device 1400 can be similar to and/or substantially the same as one
or more portions (and/or combination of portions) of the devices
100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200,
and/or 1300 described above. Thus, portions of the device 1400 may
not be described in further detail herein.
[0152] The device 1400 includes at least a housing 1410, a catheter
1430, and an actuator 1450. The housing 1410 can be any suitable
configuration. As described above with reference to previous
embodiments, the housing 1410 includes a first port 1411 configured
to be fixedly coupled to a proximal end portion 1431 of the
catheter 1430 and a second port 1412 configured to receive a distal
end portion 1432 of the catheter 1430. The housing 1410 can differ,
however, by having a cavity structure 1416 and an extension
structure 1418. As shown in FIGS. 28-30, the cavity structure 1416
can be disposed at or near a proximal end portion of the housing
1410 and can be coupled to and/or otherwise can include the first
port 1411 (e.g., a proximal port). The extension structure 1416 is
coupled to the cavity structure 1416 and can be disposed at or near
a distal end portion of the housing 1410. The extension structure
1416 can be coupled to and/or can otherwise include the second port
1412 (e.g., a distal port).
[0153] As shown in FIGS. 28-30, the cavity structure 1416 can be
substantially conical or the like with a base end or surface (e.g.,
a larger end or surface) forming a proximal surface of the housing
1410 and an apex end (e.g., a smaller end) coupled to the extension
structure 1418. Accordingly, in this embodiment, the housing 1410
can have a substantially funnel-like shape. The cavity structure
1416 is configured to hold at least a portion of the catheter 1410.
More particularly, prior to placing the catheter 1430 in the second
position, the cavity structure 1416 can hold and/or house at least
a portion of the catheter 1430 in a spooled, coiled, wound, and/or
looped configuration and/or arrangement, as shown in FIGS. 28 and
29. The extension portion 1418 can be configured to hold and/or
receive at least the distal end portion 1432 of the catheter 1430
in, for example, a linear, straight, and/or substantially
non-coiled configuration and/or arrangement.
[0154] The catheter 1430 of the device 1400 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 1430 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, 730, 830, 930, 1030, 1130, 1230, and/or 1330
described above. Thus, such similar portions and/or aspects of the
catheter 1430 may not described in further detail herein. For
example, in the embodiment shown in FIGS. 28-30, the catheter 1430
can be formed from any suitable material and can have any suitable
length, diameter, and/or configuration such as those described
above with reference to the catheter 130.
[0155] At least a portion of the catheter 1430 is movably disposed
within the housing 1410. In some embodiments, the catheter 1430 or
a portion thereof can be moved (e.g., via rotational movement of
the actuator 1450) between a first position (FIG. 28), in which a
portion of the catheter 1430 is spooled and/or wound in the cavity
structure 1416 and the distal end portion 1432 of the catheter 1430
is disposed within the extension structure 1418 and/or the second
port 1412, and a second position (FIG. 30), in which at least a
portion of the catheter 1430 extends through the second port 1412
and at least a portion of an access device coupled to the second
port 1412 (not shown). In some embodiments, the catheter 1430 can
have a length sufficient to place a distal surface of the catheter
1430 a predetermined, desired, and/or at least a threshold distance
beyond a distal surface of the access device when the catheter 1430
is in the second position, as described in detail above.
[0156] The actuator 1450 of the device 1400 can be any suitable
shape, size, and/or configuration. For example, as shown in FIGS.
28-30, the actuator 1450 includes a first portion 1451 and a second
portion 1452. The actuator 1450 can be coupled to the extension
structure 1418 of the housing 1410 at or near the second port 1412.
In other embodiments, the actuator 1450 can be coupled to the
housing 1410 at any suitable position along a length of the housing
1410. The actuator 1450 can be coupled to the housing 1410 in any
suitable manner that allows the actuator 1450 to be rotated
relative to the housing 1410. Moreover, the actuator 1450 can be
coupled to the housing 1410 such that the second portion 1452 is at
least partially disposed within the housing 1410 and in contact
with and/or otherwise allowed to engage the catheter 1430. In this
manner, the actuator 1450 can be substantially similar in at least
form and/or function to the actuator 250 described above with
reference to FIGS. 3 and 4.
[0157] In use, the device 1400 can be in a first configuration
and/or state in which the portion of the catheter 1430 (e.g., the
proximal end portion 1431) is spooled and/or wound in the cavity
structure 1416 and the distal end portion 1432 of the catheter 1430
is disposed within the extension structure 1418 and/or the second
port 1412 (FIG. 28) and a user can manipulate the device 1400 by
engaging the first portion 1451 of the actuator 1450 to transition
the device 1400 to a second configuration and/or state (FIG. 30).
For example, the user can exert a force on the first portion 1451
of the actuator 1450 to rotate the actuator 1450 in, for example, a
clockwise direction, as indicated by the arrow SS in FIG. 29. As
such, the second portion 1452 of the actuator 1450 rotates relative
to the housing 1410 and engages the catheter 1430 to move the
catheter 1430 in the distal direction from the first position
toward the second position, as indicated by the arrow TT in FIG.
29. The movement and/or transitioning of the catheter 1430 from the
first position toward the second position is such that the catheter
1430 unspools and/or uncoils within the cavity structure 1416 and
allowed to advance (e.g., in a linear direction) through the
extension structure 1418. In some instances, the funnel shape of
the housing 1410 can be such that the catheter 1430 contacts and/or
is otherwise guided or directed by an internal surface of the
housing 1410 (e.g., an internal surface of the cavity structure
1416). As shown in FIG. 30, in some instances, the catheter 1430
can be fully extended (e.g., substantially straight or linear) when
the catheter 1430 is in the second position. In some
implementations, when the second port 1412 of the housing 1410 is
coupled to an access device or the like (not shown), the catheter
1430 can be advanced to a desired position relative to the access
device, as described in detail above with reference to the device
100.
[0158] Although not shown in FIGS. 28-30, in some embodiments, the
housing 1410 and/or the cavity structure 1416 further include one
or more internal structures within the cavity structure 1416
configured to guide and/or direct the spooling (or unspooling),
winding (or unwinding), coiling (or uncoiling), etc. of the
catheter 1430. For example, FIGS. 31-33 illustrate a fluid transfer
device 1500 according to another embodiment. The fluid transfer
device 1500 (also referred to herein as "device") can be any
suitable shape, size, and/or configuration. For example, at least a
portion of the device 1500 can be similar to and/or substantially
the same as one or more portions (and/or combination of portions)
of the devices 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000,
1100, 1200, 1300, and/or 1400 described above. More particularly,
the device 1500 can be substantially similar in at least form
and/or function to the device 1400 described above with reference
to FIGS. 28-30. Thus, portions of the device 1500 may not be
described in further detail herein.
[0159] The device 1500 includes at least a housing 1510, a catheter
1530, and an actuator 1550. The housing 1510 can be substantially
similar in at least form and/or function to the housing 1410
described above with reference to FIGS. 28-30. For example, the
housing 1510 includes a cavity structure 1516 disposed at or near a
proximal end portion of the housing 1510 and an extension structure
1518 coupled to the cavity structure 1516 and disposed at or near a
distal end portion of the housing 1510. The cavity structure 1516
can be coupled to and/or otherwise can include a first port 1511
(e.g., a proximal port) and the extension structure 1516 can be
coupled to and/or otherwise can include the second port 1512 (e.g.,
a distal port). The first port 1511 is configured to be fixedly
coupled to a proximal end portion 1531 of the catheter 1530 and the
second port 1512 is configured to receive a distal end portion 1532
of the catheter 1530, as described in detail above with reference
to the housing 1410.
[0160] The housing 1510 can differ from the housing 1410, however,
by including an internal structure 1517 disposed within the cavity
structure 1516. As shown, the internal structure 1517 can be, for
example, a conical internal structure that is adjacent to and/or
extends from a proximal end or surface of the housing 1510. The
internal structure 1517 is configured to support and/or guide at
least a portion of the catheter 1530 that is disposed within the
cavity structure 1516 as the catheter 1530 is moved between a first
position (FIG. 31) and a second position (FIG. 33). For example, in
some embodiments, the internal structure 1517 and an internal
surface of the cavity structure 1516 can collectively define a
relatively small space and/or volume that can receive at least a
portion of the catheter 1530, as described in further detail
herein. Moreover, the internal structure 1516 and/or the internal
surface of the cavity structure 1516 can selectively contact,
support, and/or guide the catheter 1530 as it is advanced through
the housing 1510. In some embodiments, all or nearly all of the
catheter 1530 disposed in the housing 1510 can be supported by a
portion of the housing 1510 and/or actuator 1550. Although not
shown in FIGS. 31-33, the arrangement of the internal structure
1517 can include an opening, coupler, and/or any other suitable
feature configured to allow the first port 1511 to be fixedly
coupled to the proximal end portion 1531 of the catheter 1530.
[0161] The catheter 1530 of the device 1500 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 1530 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, 730, 830, 930, 1030, 1130, 1230, 1330, and/or 1430
described above. Thus, such similar portions and/or aspects of the
catheter 1530 may not described in further detail herein. For
example, in the embodiment shown in FIGS. 31-33, the catheter 1530
can be formed from any suitable material and can have any suitable
length, diameter, and/or configuration such as those described
above with reference to the catheter 130.
[0162] At least a portion of the catheter 1530 is movably disposed
within the housing 1510. In some embodiments, the catheter 1530 or
a portion thereof can be moved (e.g., via rotational movement of
the actuator 1550) between a first position and a second position.
For example, as shown in FIG. 31, when the catheter 1530 is in the
first position, a portion of the catheter 1530 is spooled and/or
wound about the internal structure 1517 within the cavity structure
1516 and the distal end portion 1532 of the catheter 1530 is
disposed within the extension structure 1518 and/or the second port
1512. As shown in FIG. 33, when the catheter 1530 is in the second
position, at least a portion of the catheter 1530 extends through
the second port 1512 and at least a portion of an access device
coupled to the second port 1512 (not shown). In some embodiments,
the catheter 1530 can have a length sufficient to place a distal
surface of the catheter 1530 a predetermined, desired, and/or at
least a threshold distance beyond a distal surface of the access
device when the catheter 1530 is in the second position, as
described in detail above.
[0163] The actuator 1550 of the device 1500 can be any suitable
shape, size, and/or configuration. For example, as shown in FIGS.
31-33, the actuator 1550 includes a first portion 1551 and a second
portion 1552. The actuator 1550 can be coupled to the extension
structure 1518 of the housing 1510 at or near the second port 1512.
In other embodiments, the actuator 1550 can be coupled to the
housing 1510 at any suitable position along a length of the housing
1510. The actuator 1550 can be coupled to the housing 1510 in any
suitable manner that allows the actuator 1550 to be rotated
relative to the housing 1510. Moreover, the actuator 1550 can be
coupled to the housing 1510 such that the second portion 1552 is at
least partially disposed within the housing 1510 and in contact
with and/or otherwise allowed to engage the catheter 1530. In this
manner, the actuator 1550 can be substantially similar in at least
form and/or function to the actuator 250 described above with
reference to FIGS. 3 and 4.
[0164] In use, the device 1500 can be in a first configuration
and/or state in which the portion of the catheter 1530 (e.g., the
proximal end portion 1531) is spooled and/or wound about the
internal structure 1517 within the cavity structure 1516 and the
distal end portion 1532 of the catheter 1530 is disposed within the
extension structure 1518 and/or the second port 1512 (FIG. 31) and
a user can manipulate the device 1500 by engaging the first portion
1551 of the actuator 1550 to transition the device 1500 to or
toward a second configuration and/or state (FIG. 33). For example,
the user can exert a force on the first portion 1551 of the
actuator 1550 to rotate the actuator 1550 in, for example, a
clockwise direction, as indicated by the arrow UU in FIG. 32. As
such, the second portion 1552 of the actuator 1550 rotates relative
to the housing 1510 and engages the catheter 1530 to move the
catheter 1530 in the distal direction from the first position
toward the second position. The movement and/or transitioning of
the catheter 1530 is such that the catheter 1530 unspools and/or
uncoils within the cavity structure 1516 and is allowed to advance
(e.g., in a linear direction) through the extension structure 1518.
In some instances, the conical shape of the internal structure 1517
and the conical shape of the interior surface of the cavity
structure 1516 can be such that the catheter 1530 contacts and/or
is otherwise guided or directed as the catheter 1530 is moved from
the first position toward the second position. As shown in FIG. 33,
in some instances, the catheter 1530 can be fully extended (e.g.,
substantially straight or linear) when the catheter 1530 is in the
second position. In some implementations, when the second port 1512
of the housing 1510 is coupled to an access device or the like (not
shown), the catheter 1530 can be advanced to a desired position
relative to the access device, as described in detail above with
reference to the device 150.
[0165] FIGS. 34-39 illustrate a fluid transfer device 1600
according to another embodiment. The fluid transfer device 1600
(also referred to herein as "device") can be any suitable shape,
size, and/or configuration. For example, at least a portion of the
device 1600 can be similar to and/or substantially the same as one
or more portions (and/or combination of portions) of the devices
100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200,
1300, 1400, and/or 1500 described above. More specifically, the
device 1600 can be substantially similar in at least form and/or
function to the devices 900, 1000, and/or 1100 (or any suitable
combinations thereof) described in detail above. Thus, portions of
the device 1600 may not be described in further detail herein.
[0166] The device 1600 includes at least a housing 1610, a catheter
1630, and an actuator 1650. The housing 1610 can be substantially
similar to the housing 910, 1010, and 1110, described in detail
above. For example, the housing 1610 includes a first port 1611
that can be configured to be coupled to and/or to otherwise receive
a proximal end portion 1631 of the catheter 1630 and a second port
1612 configured to receive a distal end portion 1632 of the
catheter 1630. In some embodiments, the first port 1611 can be
configured to fixedly couple to the proximal end portion 1631 of
the catheter 1630, as described above with reference to the devices
700, 800, 900, 1000, and 1100. The housing 1610 can be any suitable
shape, size, or configuration. In some embodiments, the housing
1610 or portions thereof can have a circular cross-sectional shape
defined with respect to a top view plane. In some embodiments, each
of the first port 1611 and the second port 1612 can extend from a
circumferential edge or surface of the housing 1610 (e.g., the
circumferential surface along the perimeter of the housing), as
shown for example in FIGS. 34-36 and. The first port 1611 and the
second port 1612 can be positioned along the circumferential edge
of the housing such that an axis defined by a lumen of the first
port 1611 is substantially parallel to an axis defined by a lumen
of the second port 1612. In some embodiments, the first port 1611
of the housing 1610 can be enclosed by a cover 1619 configured to
receive at least a portion of the catheter 1630 to protect the at
least the portion of the catheter 1630 from undesirable bending,
flexing, and/or kinking. In some embodiments, the cover 1619
includes and/or forms a stopper 1620 configured to limit, restrict,
and/or otherwise at least partially define a range of motion
associated with the movement of the actuator 1650 (e.g., a
rotational range of motion).
[0167] The catheter 1630 of the device 1600 can be any suitable
shape, size, and/or configuration. For example, in some
embodiments, the catheter 1630 can be substantially similar in at
least form and/or function to any of the catheters 130, 230, 330,
430, 530, 630, 730, 830, 930, 1030, 1130, 1230, 1330, 1430, and/or
1530 described above. Thus, such similar portions and/or aspects of
the catheter 1630 may not be described in further detail herein.
For example, in some embodiments, the catheter 1630 can be formed
of a single material and can have a predetermined length,
diameter(s), and/or configuration such as those described above
with reference to the catheter 130. In other embodiments, the
catheter 1630 can be formed of different materials and/or can have
different size, shape, diameter, thickness, etc. to result in any
suitable stiffness, flexibility, hardness, and/or durometer. For
example, the proximal end portion 1631 of the catheter 1630 can be
formed from a flexible material which can deform in response to a
bending force or a sudden change in pressure. In some instances,
the proximal end portion 1631 of the catheter 1630 can deform in
response to a negative pressure having a magnitude that exceeds a
threshold amount or magnitude of negative pressure, which in turn,
can reduce the likelihood of collapsing a portion of the catheter
1630 at a location downstream of the proximal end portion 1631
(e.g., the distal end portion 1632 and/or any other suitable
portion). The distal end portion 1632 of the catheter 1630 can be
formed from a relatively rigid material or a material having a
stiffness or rigidity that is at least greater than the stiffness
or rigidity of the proximal end portion 1631 of the catheter 1630.
In some embodiments, the distal end portion 1632 can have a
diameter smaller than a diameter of the proximal end portion 1631
to facilitate advancing at least a portion of the catheter 1630 to
and/or from a desired position relative to a PIV. In some
embodiments, the proximal end portion 1631 and the distal end
portion 1632 of the catheter 1630 can be separate components having
different length, length, diameter and/or configuration, which can
be mechanically and fluidically connected at or within, for
example, the first port 1611, the cover 1619, and/or any other
suitable portion of the housing 1610. For example, in some
embodiments, a secondary catheter or an external catheter can be
disposed outside of the housing 1610 and can include a distal end
portion that is at least partially disposed in the first port 1611
and/or the cover 1619 and coupled to the proximal end portion of
the catheter 1630 using any suitable coupler, adapter, connector,
and/or the like.
[0168] As described with reference to the device 100, in some
instances, the proximal end portion 1631 of the catheter 1630 can
include a clamp 1633, which can be configured to physically and/or
fluidically couple to a fluid source and/or fluid reservoir (e.g.,
a sample bottle). As such, a volume of fluid (e.g., bodily fluid,
medicament, saline, etc.) can be transferred between the catheter
1630 (and, in turn, a patient) and a fluid source or fluid
reservoir via the coupler 1633. In some embodiments, the coupler
1633 can be a clamp, grommet, o-ring, compression member, Luer
Lok.TM., and/or any other suitable coupler. For example, FIGS.
34-36 show the connector 1633 can be a female Luer Lok.TM. with an
integrated clamp.
[0169] The actuator 1650 of the device 1600 can be any suitable
shape, size, and/or configuration. In some embodiments, the
actuator 1650 can be substantially similar to the actuators 950
and/or 1050 described in detail above. For example, as shown in
FIGS. 34-37, the actuator 1650 is at least partially disposed
within the housing 1610 and has a spool structure 1654 that is
movably coupled to the housing 1610. As shown in FIGS. 34, 36 and
37, the spool structure 1654 includes a pair of engagement
structures 1657 that are disposed in a mirrored orientation
relative to each other and that define (1) an inner channel or path
1658 between interior, inner, and/or adjacent portions thereof, and
(2) an outer channel 1615 defined between the exterior or outer
portion and/or surface of the spool structure 1654 and an interior
or inner portion and/or surface of the housing 1610 (e.g., an inner
perimeter).
[0170] As shown, the actuator 1650 includes an engagement feature
1659 disposed on the outside of the actuator 1650 (e.g., outside of
the housing 1610). In some implementations, a user can engage,
contact, and/or exert a force on the engagement feature 1659 to
move the actuator 1650 relative to the housing 1610 (e.g., in a
rotational motion about the axis 1699 shown in FIGS. 34 and 35). As
described above with reference to the devices 900, 1000, and/or
1100, the movement of the actuator 1650 results in and/or otherwise
causes at least a portion of the catheter 1630 that is wound or
coiled inside the housing 1610 to be advanced through one or more
portions of the housing 1610. Moreover, as shown, the engagement
feature 1659 is disposed at or near a circumference or edge of the
actuator 1650. To prevent extending the winding (or unwinding) of
the catheter 1630 beyond predetermined positions, the cover 1619
can include a stopper feature 1620 positioned in the path of the
engaging feature 1659 along the circumference of the actuator 1650
(or housing 1610), thereby restricting or at least partially
defining the movement of the engagement feature 1659, and thus the
actuator 1650, relative to the housing 1610.
[0171] The catheter 1630 is disposed within the housing 1610 such
that a portion of the catheter 1630 is disposed within at least one
of the outer channel 1615 and/or the inner channel 1658 and is
configured to be advanced therethrough (e.g., through the housing
1610) in response to actuation of the actuator 1650. For example,
FIGS. 34, 36 and 39 illustrate the device 1600 in a first
configuration and/or state in which the catheter 1630 is in a first
position. When the catheter 1630 is in the first position, a
portion of the catheter 1630 can extend from the first port 1611,
through a first portion 1615A of the outer channel 1615, through
the inner channel 1658, through a second portion 1615B of the outer
channel 1615 and into the second port 1612. As shown in FIG. 39,
when the device 1600 is in the first configuration and/or state,
the catheter 1630 can pass through the first portion 1615A of the
outer channel 1615 to a position near the second port 1612. Rather
than extending from the first portion 1615A of the outer channel
1615 into the second port 1612, the catheter 1630 extends through
the inner channel 1658 from a position near the second port 1612 to
a position near the first port 1611. As such, the catheter 1630
substantially wraps around one of the engagement structures 1657.
From the position at or near the first port 1611, the catheter 1630
further extends through the second portion 1615B of the outer
channel 1615 (e.g., defined at least in part by the other
engagement structure 1657) and to a position at, near, or at least
partially within the second port 1612. In this position and/or
orientation, the path along the outer channel 1615 and the inner
channel 1658 through which the catheter 1630 extends between the
first port 1611 and the second port 1612 is, for example, the
longest or substantially the longest path between the first port
1611 and the second port 1612 of the housing 1610, and the largest
or substantially the largest portion of the catheter 1630 is
disposed within the housing 1610 when the device 1600 is in the
first configuration and/or state (e.g., when the actuator 1650
and/or catheter 1630 is/are in the first position).
[0172] The device 1600 can be transitioned from the first
configuration and/or state to a second configuration and/or state
by manipulating the engaging feature 1659 of the actuator 1650 to
move or rotate the actuator 1650 about a central axis 1699 defined
by the housing 1610 in a clockwise direction, as indicated by the
arrow(s) VV in FIG. 34. The movement of the actuator 1650 results
in a rotation of the spool structure 1654 and the engagement
structures 1657, which in turn, change a portion of the outer
channel 1615 that is disposed between the first port 1611 and a
first end portion of the inner channel 1658 (at or near the second
port 1612), and a portion of the outer channel 1615 that is
disposed between the second port 1612 and a second end portion of
the inner channel 1658 opposite the first end portion (at or near
the first port 1611), as shown in FIG. 35. More specifically, the
portions of the outer channel 1615 are reduced, which in turn, is
operable to advance the catheter 1630 through a serpentine,
circuitous, tortuous, and/or otherwise curved or non-linear path
collectively formed and/or defined by the outer channel 1615 and
the inner channel 1658 from its first position toward its second
position. Said another way, rotation of the actuator 1650 relative
to the housing 1610 results in a rotation of the engagement
structures 1657 relative to the first port 1611 and the second port
1612. Moreover, the rotation of the engagement structures 1657
moves and/or changes an orientation of the inner channel 1658
relative to the first port 1611 and the second port 1612.
[0173] The engaging feature 1659 can be manipulated to move the
actuator 1650 a predetermined and/or desired amount to place the
device 1600 in the second configuration and/or state in which the
catheter 1630 is in the second position. In some implementations,
the actuator 1650 can be rotated approximately 180.degree. to
transition the device 1600 from the first configuration to the
second configuration. In this position and/or orientation, the
outer channel 1615 and the inner channel 1658 can define, for
example, the shortest path through the housing 1610 between the
first port 1611 and the second port 1612. For example, in some
implementations, the arrangement of the engagement structures 1657
is such that when the device 1600 is in the second configuration
and/or state, the catheter 1630 can extend between the first port
1611 and the second port 1612 via the inner channel 1658 and
without substantially extending through the outer channel 1615
(e.g., neither the first portion nor the second portion of the
outer channel 1615).
[0174] As described in detail above with reference to previous
embodiments, the arrangement of the device 1600 can allow the
catheter 1630 to have a length or "reach" that can be longer than,
for example, the housing 1610 and/or a length of the housing 1610
between the first port 1611 and the second port 1612 (e.g., via the
inner channel 1658). Thus, when the second port 1612 of the housing
1610 is coupled to an access device or the like (not shown), the
catheter 1630 can be advanced to a desired position relative to the
access device without the device 1600 having an undue length
regardless of a type and/or length of the access device, as
described in detail above with reference to the device 100.
[0175] The arrangement of the device 1600 is such that manipulating
the engaging feature 1659 to move or rotate the actuator 1650 an
angular amount or distance (e.g., an amount of rotation) results in
the distal end portion 1632 of the catheter 1630 being moved a
linear amount or distance. In other words, linear displacement
(e.g., translation) of the distal end portion 1632 of the catheter
1630 is achieved with an angular displacement (e.g., rotation) of
the actuator 1650. In some implementations, the actuator 1650, the
spool structure 1654, and/or the engagement structures 1659, are
configured to achieve a "length multiplying" and/or "displacement
multiplying" effect and/or otherwise configured to provide a
mechanical advantage such that a relatively small amount of
rotation of the engagement feature 1659 of the actuator 1650
results in a relatively large amount of translation of the distal
end portion 1632 of the catheter 1630 (or at least an amount of
translation that is greater than the amount of rotation).
[0176] As described above, the movement of the actuator 1650 causes
the distal end portion 1632 of the catheter 1630 to be moved an
amount or distance in a linear direction. Such movement of the
actuator exerts a force on the portions of the catheter 1630 that
are wound or coiled inside the housing 1610. The arrangement of the
device 1600 is such that the all or substantially all the portions
of the catheter 1630 disposed within the housing 1610 are supported
by the a surface of the housing 1610 and/or actuator 1650 that
defines the outer channel 1615 and/or the inner channel 1658, which
can, for example, provide tangential support along the portions of
the catheter 1630 disposed within the housing 1610 when the
actuator 1650 exerts the force operable to move the catheter 1630
through the housing 1610. As a result, the catheter 1630 can be
advanced avoiding undesired bending, kinking, or deformation that
may otherwise be associated with "pushing" or advancing an
unsupported length of a catheter (or other relatively flexible
tube, member, etc.).
[0177] In some embodiments, the supported path or trajectory that
the portions of the catheter 1630 disposed inside the housing 1610
(e.g., that are wound or coiled inside the housing 1610) can be
advanced along in response to movement of the actuator 1650 is
defined by the inner surfaces of the engagement structures 1657
defining the inner channel 1615 and/or the outer surfaces of the
engagement structures 1657 and the corresponding inner surface of
the housing 1610 that define the outer channel 1658. In this way,
when the actuator 1650 is moved, the portions of the catheter 1630
disposed inside the housing 1610 are supported, guided, directed,
and/or otherwise allowed to move along this supported path of
trajectory, which in turn, limits and/or substantially prevents
undesired deformation, coiling, bending, bowing, and/or deflection
of or more portions of the catheter 1630 inside the housing 1650
that may limit and/or substantially prevent a desired linear
displacement of the distal end portion 1632 of the catheter
1630.
[0178] While the actuator 1650 has been described as moving and/or
being moved in a clockwise direction to transition the device 1600
from the first configuration and/or state to the second
configuration and/or state, as indicated by the arrow VV in FIG.
34, the actuator 1650 can alternatively be configured to move in a
counterclockwise direction to transition the device 1600 from the
first configuration and/or state to the second configuration. For
example, the arrangement of the spool structure 1654 and/or the
arrangement of the catheter 1630 passing through the inner channel
1658 can be inverted with respect to the in-plane axis of the
device 1600 such that counterclockwise movement of the actuator
1650 changes a portion of the outer channel 1615 that is disposed
between the first port 1611 and a first end portion of the inner
channel 1658, and a portion of the outer channel 1615 that is
disposed between the second port 1612 and a second end portion of
the inner channel 1658 opposite the first end portion.
[0179] In some instances, the user can rotate the actuator 1650 in
a first direction to transition the device from the first
configuration to the second configuration, and thus advance the
catheter 1630 from the first position to the second position, as
described in detail above. In some instances, the user can then,
after the device has been transitioned from the first configuration
to the second configuration, rotate the actuator 1650 in a second
direction opposite to the first direction, to retract the catheter
1630 from the second position back to the first position, or to a
position such that a large portion or length of the catheter 1630
is disposed within the housing 1610 between the first port 1611 and
the second port 1612. Alternatively, in some instances, the user
can first rotate the actuator 1650 to transition the device from
the first configuration to the second configuration, and thus
advance the catheter 1630 from the first position to the second
position, and then continue to rotate the actuator 1650 in the same
direction to retract the catheter 1630 from the second position to
a third position in which a portion or length of the catheter 1630
is disposed within the housing 1610 between the first port 1611 and
the second port 1612 (e.g., the catheter 1630 is looped around the
actuator 1650 in an opposite direction). For example, in some
implementations, the actuator 1650 can be rotated about 180.degree.
to move the catheter 1630 from the first position to the second
position, and then can be rotated beyond 180.degree. (e.g., until
the engagement feature 1659 hits the stop 1620) to move the
catheter from the second position to the third position.
[0180] Referring now to FIG. 40, a flowchart is presented
illustrating a method 10 of using a fluid transfer to transfer
fluid to or from a patient through an indwelling vascular access
device according to an embodiment. The fluid transfer device can be
similar to and/or substantially the same as any of the fluid
transfer devices 100, 200, 300, 500, 600, 700, 800, 900, 1000,
1100, 1200, 1300, 1400, 1500, and/or 1600 described in detail
above. Accordingly, the fluid transfer device (also referred to
herein as "device") can include a housing, a catheter at least
partially disposed in the housing, and an actuator coupled to the
housing and selectively engaging the catheter. The housing includes
a first port and a second port. The first port can be fixedly
coupled to a proximal end portion of the catheter. The method 10
includes coupling the second port of the housing to an indwelling
vascular access device, at 11. For example, in some embodiments, a
user can manipulate the fluid transfer device to physically and
fluidically couple the second port of the housing of the fluid
transfer device to an indwelling vascular access device such as an
indwelling peripheral intravenous line (PIV), and extended-dwell
PIV, a midline PIV, a PICC line and/or the like. The arrangement of
the catheter of the fluid transfer device can be such that the
proximal end portion of the catheter is fixedly coupled to and/or
otherwise maintained in a fixed position relative to the first
port. In some embodiments, the second port of the housing can be
and/or can include a Luer Lok.TM., a "Clip-Lock-Snap" connection,
and/or the like configured to physically and fluidically couple to,
for example, the PIV.
[0181] The actuator of the fluid transfer device is rotated an
angular distance about a central axis defined by the housing of the
fluid transfer device, at 12. For example, in some embodiments the
housing can define a range of motion of the actuator. The housing
can include a structure, feature, component, and/or the like that
can selectively engage a portion of the actuator to limit,
restrict, guide, and/or otherwise direct an amount or direction of
movement of a portion of the actuator. Thus, the actuator can be
rotated through a desired range of motion and/or through a desired
angular displacement based at least in part on a size and/or
arrangement of a portion of the actuator, a size and/or arrangement
of a portion of the housing, and/or the like--similar to the
actuators described in detail with reference to the device 900,
1000, 1100 and 1600.
[0182] A distal end portion of the catheter is advanced, in
response to the rotation of the actuator, a linear distance from a
first position to a second position, at 13. In the first position,
the distal end portion of the catheter is in the housing, and in
the second position, the distal end portion of the catheter is
distal to the indwelling vascular access device. The distal end
portion of the catheter is advanced linearly in a direction
orthogonal to the central axis through the second port and the
indwelling access device. In some embodiments, the rotation of the
actuator through a rotational and/or angular displacement can
advance, coil (or uncoil), spool (or unspool), and/or otherwise
move the distal end portion of the catheter disposed within the
housing. For example, the rotation of the actuator relative to the
housing and the advancement of the catheter (or at least the distal
end portion thereof) can be substantially similar to the rotation,
advancement, etc., described in detail above with reference to the
device 1600. In this manner the arrangement of the fluid transfer
device can be such that the catheter has a length sufficient to
extend a desired distance (e.g., at least partially into or through
a standard or short PIV, an extended-dwell PIV, a midline PIV, a
PICC line, and/or any other suitable access device). Similarly, the
catheter can have a length that is sufficient to allow the second
port of the housing to be coupled to any suitable adapter,
extension set, tube, port, etc. In some instances, for example, the
catheter can have a length that is sufficient to extend from the
housing, through an IV extension set and/or any suitable length of
tubing coupled thereto, through a port of an PIV (e.g., a proximal
port and/or a side port), and to a position within a vein of a
patient distal to the PIV.
[0183] While the devices 100, 200, 300, 400, 500, 700, 800, 900,
1000, 1100, 1200, 1300, 1400, and 1500 have been shown and/or
described above as being coupled to an access device such as a PIV,
in other embodiments, the devices can be coupled to any suitable
access device, introducer, adapter, secondary or intermediate
device, etc. For example, in some instances, the second port 212 of
the housing 210 of the device 200 can be coupled to and extension
set or the like, which in turn, is coupled to an indwelling PIV
such as those described herein. The extension set can be, for
example, a dual port IV extension set such as a "Y-adapter" or
"T-adapter." In this manner, the terms "Y-adapter" and "T-adapter"
generally describe an overall shape of the dual port IV extension
set. In other embodiments, an extension set can be a single port IV
extension set. In these embodiments, the devices described herein
can include a catheter having a length sufficient to extend from
the housing of the device, through the extension set or other
intermediate device, and through the access device to position a
distal end of the catheter distal to the access device. Moreover,
the access device can be any suitable device having any suitable
length such as, for example, a standard or short PIV, an
extended-dwell PIV, a midline PIV, a PICC line, and/or any other
device. In other embodiments, any of the devices described herein
can be coupled to any suitable access device or the like and can be
used for any suitable procedure, surgery, etc.
[0184] In some instances, the transfer devices described herein can
be assembled during one or more manufacturing processes and
packaged in a pre-assembled configuration. For example, in some
instances, the assembly of the devices can be performed in a
substantially sterile environment such as, for example, an ethylene
oxide environment, or the like. In other embodiments, the transfer
devices described herein can be packaged in a non-assembled
configuration (e.g., a user can open the package and assemble the
components to form the device). The components of the devices can
be packaged together or separately. In some embodiments, the
devices can be packaged with, for example, a PIV, an extension set,
a Y-adapter or T-adapter, and/or any other suitable component.
[0185] Any of the devices described herein can be used in any
suitable process, procedure, method, and/or the like. For example,
in some instances, the devices described herein can be used in a
medical procedure, process, and/or method for transferring fluid to
or from a patient. Some such procedures can include, for example,
aspirating a volume of bodily fluid from a patient via a previously
placed or indwelling access device. More particularly, any of the
devices described herein can be used to aspirate a volume of blood
from a patient via a previously placed or indwelling peripheral
intravenous line.
[0186] While various embodiments have been described above, it
should be understood that they have been presented by way of
example only, and not limitation. While the embodiments have been
particularly shown and described, it will be understood that
various changes in form and details may be made. Where schematics
and/or embodiments described above indicate certain components
arranged in certain orientations or positions, the arrangement of
components may be modified. Although various embodiments have been
described as having particular features and/or combinations of
components, other embodiments are possible having a combination of
any features and/or components from any of embodiments as discussed
above. For example, as described above, the device 400 can be a
combination of certain features and/or aspects of the devices 200
and 300.
[0187] Although not shown in some of the devices described herein,
any of the housings and/or actuators can include one or more
internal supports or the like configured to support the catheter
within the housing. Such internal supports can be, for example,
guides, tracks, rails, springs, sleeves, protrusions, ribs,
channels, sponges, pads, etc. configured to selectively engage a
portion of the catheter. In this manner, the internal supports can
limit and/or substantially prevent undesired deformation and/or
deflection of a portion of the catheter as the device is
transitioned between the first configuration and the second
configuration.
[0188] While described as limiting and/or substantially preventing
undesired deformation and/or deflection of the catheter, in other
embodiments, the catheter can be configured to deflect, bow, bend,
and/or reconfigure without kinking and/or permanently deforming.
For example, in some instances, a distal end surface of the
catheter may impact an obstruction or the like while being advanced
from the first position to the second position, which can at least
temporarily obstruct and/or prevent further movement of the distal
end portion of the catheter. In such instances, if a user continues
to exert a force on the actuator otherwise operable to move the
catheter toward the second position, an unsupported portion of the
catheter within the housing can bend, flex, bow, deflect, and/or
otherwise be transitioned from an "unclutched" configuration to a
"clutched" configuration. In other words, a portion of the force
exerted on the actuator and otherwise operable to advance the
catheter toward the second position is operable to deflect, bend,
flex, bow, etc. a portion of the catheter within the housing. As
such, a force transmitted to and/or through the distal surface of
the catheter (e.g., on the obstruction) is reduced, which in turn,
can reduce damage to the catheter, an access device through which
the catheter is being advanced (e.g., a PIV), a venous structure
(e.g., vein wall), and/or the like.
[0189] In some embodiments, increasing or decreasing a durometer of
the catheter, a length of the catheter, a length of the housing,
and/or an amount of support provided, for example, by an internal
support member (e.g., a guide, track, rail, spring, pad, post,
etc.) can allow for a tuning or adjustment of the amount of
deflection (e.g., "clutching") of the catheter and/or an amount of
force transferred through the catheter. In some embodiments, a
portion of the catheter can impact and/or contact an inner surface
of the housing (e.g., a sidewall) when bowed, flexed, deflected,
and/or clutched. In some embodiments, this arrangement can produce
a visual, audible, and/or haptic indication that the distal end
surface of the catheter has impacted an obstruction. In some
embodiments, an internal support member (as described above) such
as a pad or the like can be used to "tune" and/or alter for
example, an audible and/or haptic output or indication that the
distal end surface of the catheter has impacted an obstruction.
[0190] Although not described above with reference to specific
embodiments, it should be understood that any of the embodiments
described herein can be manipulated to retract a catheter from its
second position to its first position. For example, in some
instances, after withdrawing a desired volume of bodily fluid
through a catheter of a device, user can manipulate the device by
moving the actuator in a substantially opposite direction (e.g.,
rotating in a counterclockwise direction, moving in a proximal
direction, and/or any other suitable movement). As such, the
catheter can be retracted into the housing. In other words, a user
can move the actuator to move and/or transition the catheter in a
proximal direction to retract a distal end portion of the catheter
into the housing (e.g., after use or the like).
[0191] Any of the aspects and/or features of the embodiments shown
and described herein can be modified to affect the performance of
the transfer device. For example, radius of curvature of a portion
of an actuator can be increased or decreased to facilitate movement
of a catheter coupled to and/or in contact with the portion of the
actuator. In other embodiments, the length of the housing can be
increased or decreased to accommodate the catheter having an
increased or decreased length, respectively. By way of another
example, any of the components of the transfer devices described
herein can be formed from any suitable material that can result in
a desired hardness, durometer, and/or stiffness of that
component.
[0192] Where methods and/or schematics described above indicate
certain events and/or flow patterns occurring in certain order, the
ordering of certain events and/or flow patterns may be modified.
Additionally, certain events may be performed concurrently in
parallel processes when possible, as well as performed
sequentially.
