Abstract
Description
[Technical Field]
[0001]
[0001] This application claims the benefit of priority to U.S. Patent Application No. 62 / 989,371, filed March 13, 2020, which is incorporated herein by reference in its entirety. [Background technology]
[0002]
[0002] Catheters are typically placed within a patient's blood vessels using the Seldinger technique, which involves inserting a hollow needle into the blood vessel, inserting a guidewire through the needle, advancing the guidewire into the blood vessel, and removing the needle from the blood vessel, leaving the guidewire in place. A catheter is then advanced over the guidewire until it is properly positioned in the patient's vasculature. The guidewire is then removed from the patient. Summary of the Invention [Problem to be solved by the invention]
[0003]
[0003] Guidewires used in accordance with the Seldinger technique are typically packaged in a coiled tubing dispenser to maintain the guidewire in a sterile condition and reduce the hassle of handling the guidewire. However, inserting such a guidewire from the dispenser into a hollow needle requires two hands. Specifically, one hand is required to hold both the needle and the engagement piece configured to guide the guidewire into the needle, while the other hand is required to grasp the guidewire and guide it from the dispenser into the needle. Increased handling of the guidewire increases the opportunity for the guidewire to become contaminated or damaged. In view of the above, there is a need for better guidewire management during medical procedures, such as those requiring the Seldinger technique. [Means for solving the problem]
[0004]

[0022]
[0044] Before disclosing some specific embodiments in more detail, it should be understood that the specific embodiments disclosed herein do not limit the scope of the concepts presented herein. Furthermore, it should be understood that the specific embodiments disclosed herein may have features that can be readily separated from the specific embodiment and that can optionally be combined with or substituted for features of any of the many other embodiments disclosed herein.
[0023]
[0045] Furthermore, with regard to the terms used herein, it should be understood that these terms are intended to describe certain specific embodiments and do not limit the scope of the concepts presented herein. Ordinal numbers (e.g., first, second, third, etc.) are generally used to distinguish or identify various features or steps within a group of features or steps, and do not provide a definitive or numerical limit on a sequence. For example, "first," "second," and "third" features or steps do not necessarily have to appear in that order, nor are particular embodiments having such features or steps necessarily limited to only these three features or steps. Designations such as "left," "right," "top," "bottom," "front," and "rear" are used for convenience and are not intended to imply, for example, any particular fixed location, orientation, or direction. Instead, such designations are used to reflect, for example, a relative location, relative orientation, or relative direction. The singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise.
[0024]
[0046] With respect to "proximal," for example, the "proximal portion" or "proximal end portion" of a catheter disclosed herein includes the portion of the catheter intended to be closest to the clinician when the catheter is used on a patient. Similarly, for example, the "proximal length" of a catheter includes the length of the catheter intended to be closest to the clinician when the catheter is used on a patient. For example, the "proximal end" of a catheter includes the end of the catheter intended to be closest to the clinician when the catheter is used on a patient. The proximal portion, proximal end portion, or proximal length of a catheter can include the proximal end of the catheter. However, the proximal portion, proximal end portion, or proximal length of a catheter need not include the proximal end of the catheter. That is, unless the context dictates otherwise, the proximal portion, proximal end portion, or proximal length of a catheter is not the terminal portion or the terminal-most length of the catheter.
[0025]
[0047] With respect to "distal," for example, the "distal portion" or "distal end portion" of a catheter disclosed herein includes a portion of the catheter intended to be near or within a patient when the catheter is used with the patient. Similarly, for example, the "distal length" of a catheter includes the length of the catheter intended to be near or within a patient when the catheter is used with the patient. For example, the "distal end" of a catheter includes the end of the catheter intended to be near or within a clinician when the catheter is used with the patient. The distal portion, distal end portion, or distal length of a catheter can include the distal end of the catheter. However, the distal portion, distal end portion, or distal length of a catheter need not include the distal end of the catheter. That is, unless the context dictates otherwise, the distal portion, distal end portion, or distal length of a catheter is not the terminal portion or the terminal-most length of the catheter.
[0026]
[0048] Unless defined otherwise, all technical or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.
[0049] As noted above, there is a need for better guidewire management in medical procedures, such as those requiring the Seldinger technique. Disclosed herein are guidewire management devices and methods that address the above. Guidewire Management Device
[0050] 1-16 illustrate various guidewire management devices, namely, guidewire management devices 100, 300, 600, 700, 900, 1200, 1300, and 1500. For ease of explanation, the following description will first highlight features that guidewire management devices 100, 300, 600, and 700 have in common with each other and with many of the other guidewire management devices described herein. These features may be indicated among the various guidewire management devices by the same reference numeral (e.g., guidewire 102), similar reference numerals (where the reference numerals differ in prefix to reflect the figure or embodiment associated with those features, e.g., first sleeve 110, first sleeve 610, or first sleeve 710), descriptions, or combinations thereof. Indeed, common features may be similarly described among any group of guidewire management devices of the various guidewire management devices 100, 300, 600, 700, 900, 1200, 1300, and 1500. After an initial description of guidewire management devices 100, 300, 600, and 700, guidewire management devices 100, 300, 600, 700, 900, 1200, 1300, and 1500 will be described below individually or collectively with respect to some of their unique features.
[0027]
[0051] As shown, guidewire management device 100, 300, 600, or 700 has a guidewire 102, a first sleeve 110, 610, or 710, and a second sleeve 120, 620, or 720.
[0028]
[0052] The first sleeve 110, 610, or 710 is configured to have a lumen (i.e., an inner cavity) for feeding or advancing the guidewire 102 distally and out of the guidewire management device 100, 300, 600, or 700. The first sleeve 110, 610, or 710 has a distal portion configured as a male connector with a Luer taper for connecting the first sleeve 110, 610, or 710 to a complementary female connector, such as a connector on the hub of a hollow needle or catheter. The male connector is configured such that when mated with such a complementary female connector on, for example, the catheter, guidewire management device 100, 300, 600, or 700 forms a single unit with the catheter, thereby allowing the single unit to be held in one hand for guidewire management (e.g., feeding guidewire 102 distally out of guidewire management device 100, 300, 600, or 700 and into the catheter). (See FIG. 17.) First sleeve 110, 610, or 710 also has a proximal portion having a bore (i.e., hole) 112, 612 (not shown), or 712, and the lumen of first sleeve 110, 610, or 710 opens to the interior of this bore. The bore 112, 612, or 712 is configured to accommodate or receive the distal portion of the sterile barrier 104 or 304 when the guidewire 102 is advanced distally and out of the guidewire management device 100, 300, 600, or 700.
[0029]
[0053] First sleeve 110, 610, or 710 is further configured to advance or retract guidewire 102 proximally into guidewire management device 100, 300, 600, or 700. First sleeve 110, 610, or 710 is configured to straighten guidewire 102 (e.g., a J-shaped tip of the guidewire) when advancing guidewire 102 proximally into guidewire management device 100, 300, 600, or 700. (See FIGS. 7 and 8 for the J-shaped tip of guidewire 102 according to some embodiments.) First sleeve 110, 610, or 710 can have a seal, such as an “O” ring 114, 614 (not shown), or 714, configured to prevent fluid (e.g., blood) from entering guidewire management device 100, 300, 600, or 700 as the guidewire is advanced proximally into guidewire management device 100, 300, 600, or 700. The seal, such as “O” ring 114, 614, or 714, is further configured to prevent fluid (e.g., air) from leaking out of guidewire management device 100, 300, 600, or 700 as the guidewire is advanced proximally into guidewire management device 100, 300, 600, or 700, thereby minimizing or eliminating the risk of air embolism.
[0030]
[0054] A second sleeve 120, 620, or 720 is proximal to the first sleeve 110, 610, or 710 within the guidewire management device 100, 300, 600, or 700, such that at least a partial length of the guidewire 102 extends between the first sleeve 110, 610, or 710 and the second sleeve 120, 620, or 720. This at least a partial length of the guidewire 102 extending between the first sleeve 110, 610, or 710 and the second sleeve 120, 620, or 720 is disposed within the sterile barrier 104 or 304.
[0031]
[0055] The second sleeve 120, 620, or 720 is configured with a lumen for routing the guidewire 102 in cooperation with the first sleeve 110, 610, or 710, such as routing the guidewire 102 distally and out of the guidewire management device 100, 300, 600, or 700. The second sleeve 120, 620, or 720 has a proximal portion optionally having a bore 122, and the lumen of the second sleeve 120, 620, or 720 opens to the interior of this bore. For example, the second sleeve 120 has a proximal portion having a bore 122, while the second sleeve 620 or 720 has a proximal portion without such a bore. Whether or not the second sleeve 120, 620, or 720 has such a bore, the second sleeve 120, 620, or 720 may further have a constriction 124, recess 724, or similar stopping means for stopping the end of the guidewire 102, such as its bulbous end or slug end, from passing completely through the second sleeve 120, 620, or 720 as the guidewire 102 is advanced distally out of the guidewire management device 100, 300, 600, or 700. Because the narrowed portion 124, recess 724, or similar stopping means is configured to stop the end of the guidewire 102 from passing completely through the second sleeve 120, 620, or 720, the narrowed portion 124, recess 724, or similar stopping means is further configured to stop the guidewire from passing completely through the guidewire management device 100, 300, 600, or 700 and into the patient (where the guidewire 102 may be lost).
[0032]
[0056] Second sleeve 120, 620, or 720 is further configured to cooperate with first sleeve 110, 610, or 710 to route guidewire 102 proximally into guidewire management device 100, 300, 600, or 700. Second sleeve 120, 620, 720 has a distal portion with bore 126, 626 (not shown), or 726, into which the lumen of second sleeve 120, 620, or 720 opens. Bore 126, 626, or 726 is configured to house or receive the proximal portion of sterile barrier 104 or 304 when guidewire 102 is routed proximally into guidewire management device 100, 300, 600, or 700.
[0033]
[0057] Guidewire 102 has a distal portion and a proximal portion.
[0058] The distal portion of guidewire 102 can have a J-shaped tip configured to straighten the tip of guidewire 102 as it enters first sleeve 110, 610, or 710 when guidewire 102 is advanced proximally into guidewire management device 100, 300, 600, or 700. When guidewire 102 is advanced distally out of guidewire management device 100, 300, 600, or 700, the J-shaped tip is configured to reform the "J" shape when released from the stenosis (e.g., first sleeve 110, 610, or 710). When first sleeve 110, 610, or 710 is connected to a complementary female connector, such as a connector on the hub of a hollow needle, the tip of guidewire 102 does not reform the "J" shape until the tip distally passes over the needle, such as in a blood vessel.
[0034]
[0059] The proximal portion of the guidewire 102 can have a bulbous end configured to stop the guidewire 102 from passing completely through the second sleeve 120, 620, or 720 by a narrowed portion 124, recess 724, or similar stopping means when the guidewire 102 is advanced distally and out of the guidewire management device 100, 300, 600, or 700.
[0035]
[0060] Sterility barrier 104 or 304 is configured to maintain the sterility of guidewire 102 while it is disposed therein. Importantly, the guidewire never needs to be touched by the clinician during the procedure, thereby maintaining the sterility of guidewire 102 and further ensuring that the clinician does not come into contact with bodily fluids.
[0036]
[0061] Sterility barrier 104 is a pleated bag. Sterility barrier 104 or bag 104 is configured to unpleat when pulled from second sleeve 120 of guidewire management device 100 or through second sleeve 620 or 720 of guidewire management device 600 or 700 while routing guidewire 102 distally and out of guidewire management device 100, 600, or 700. Bag 104 is further configured to pleat when inserted into first sleeve 110, 610, or 710 while routing guidewire 102 distally and out of guidewire management device 100, 600, or 700. Similarly, bag 104 is configured to unpleat when pulled from first sleeve 110, 610, or 710 while routing guidewire 102 proximally and into guidewire management device 100, 600, or 700. Bag 104 is further configured to pleat when inserted into second sleeve 120 of guidewire management device 100 or when passing through second sleeve 620 or 720 of guidewire management device 600 or 700 while advancing guidewire 102 proximally into guidewire management device 100, 600, or 700.
[0037]
[0062] Advantageously, in guidewire management devices such as guidewire management devices 600 and 700, the combination of a partial length of bag 104 and its sealed or valved end is configured to stop the end (bulbed end) of guidewire 102 from passing through what would otherwise be an opening in the proximal end of bag 104. Stopping the end of guidewire 102 from passing through such an opening prevents the tip of guidewire 102 from passing completely through first sleeve 110 and reforming the J-shaped tip as guidewire 102 is advanced proximally into guidewire management device 600 or 700.
[0038]
[0063] Described below are methods for delivering or advancing guidewire 102 distally out of guidewire management device 100, 600, or 700. Further described below are methods for delivering or retracting guidewire 102 proximally into guidewire management device 100, 600, or 700.
[0039]
[0064] Sterility barrier 304 is a bellows boot. Sterility barrier 304, or boot 304, is configured to repeatedly stretch from an equilibrium state and relax back to the equilibrium state while advancing guidewire 102 distally and out of guidewire management device 300. Similarly, boot 304 is configured to repeatedly stretch from an equilibrium state and relax back to the equilibrium state while advancing guidewire 102 proximally and into guidewire management device 300.
[0040]
[0065] Below, methods are described for delivering or advancing guidewire 102 distally and out of guidewire management device 300. Further below, methods are described for delivering or retracting guidewire 102 proximally and into guidewire management device 300.
[0041]
[0066] Although not shown for any of guidewire management devices 100, 300, 600, and 700, sterility barrier 104 or 304 may alternatively be, for example, a splittable casing 904 over the entirety of guidewire 102 or over at least a majority of guidewire 102 except within or distal to first sleeve 110, 610, or 710. Splittable casing 904 is configured to separate from guidewire 102 while routing guidewire 102 distally and out of the guidewire management device. (See, e.g., guidewire management devices 900, 1200, 1300, and 1500.) Some of the guidewire management devices described above (e.g., guidewire management devices 1300 and 1500) are configured to insert guidewire 102 into splittable casing 904 while routing guidewire 102 proximally and into the guidewire management device. Dividable casing 904 can have scale markings thereon configured to indicate the length of a portion of guidewire 102 from the distal end of guidewire 102 .
[0042]
[0067] 1-4 to illustrate at least some of the unique features of guidewire management devices 100 and 300, guidewire management devices 100 and 300 include a guidewire 102, a frame 140 having a pair of tubular rails 142, a guidewire conduit 150 threaded through the pair of tubular rails 142, a first sleeve 110 mounted on the struts between the rails of the pair of tubular rails 142, and a second sleeve 120 mounted on the struts proximal to first sleeve 110 and between the rails of the pair of tubular rails 142. At least a portion of guidewire 102 is disposed within guidewire conduit 150.
[0043]
[0068] Guidewire conduit 150 may be opaque or translucent, depending on the polymeric material selected. If guidewire conduit 150 is translucent, guidewire conduit 150 is configured to allow visualization of guidewire 102 while routing guidewire 102 distally out of guidewire management device 100 or 300 or while routing guidewire 102 proximally into guidewire management device 100 or 300.
[0044]
[0069] FIG. 5 shows the bulbous end of guidewire 102 distal to plug 152 within guidewire conduit 150, according to some embodiments.
[0070] Guidewire conduit 150 has a proximal portion with a plug 152 configured to stop the bulbous end of guidewire 102 from passing through what would otherwise be an opening in the proximal end of guidewire conduit 150. Alternatively, plug 152 is simply a constricted portion of guidewire conduit 150, which has a similar effect. Stopping the bulbous end of guidewire 102 from passing through such an opening prevents the tip of guidewire 102 from passing completely through first sleeve 110 and reforming the J-shaped tip as guidewire 102 is advanced proximally into guidewire management device 100 or 300.
[0045]
[0071] 6-16 to describe at least some of the unique features of guidewire management devices 600, 700, 900, 1200, 1300, and 1500, guidewire management device 600, 700, 900, 1200, 1300, or 1500 includes a handle 640, 740, 940, 1240, 1340, or 1540, a guidewire 102, and a first sleeve 610, 710, 910, 1240, 1340, or 1540 formed within a distal portion of handle 640, 740, 940, 1240, 1340, or 1540. 10, 1310, or 1510, a second sleeve 620, 720, 920, 1220, 1320, or 1520 formed in a proximal portion of the handle 640, 740, 940, 1240, 1340, or 1540, and a thumbwheel 642, 742, 942, 1242, 1342, or 1542 disposed under the guidewire 102 between the first sleeve 610, 710, 910, 1210, 1310, or 1510 and the second sleeve 620, 720, 920, 1220, 1320, or 1520.
[0046]
[0072] Handle 640, 740, 940, 1240, 1340, or 1540 is ambidextrous, as it is configured to be held in either the right or left hand of a clinician. Additionally, handle 640, 740, 940, 1240, 1340, or 1540 is configured to be held in at least two configurations. The first configuration, in which handle 640, 740, 940, 1240, 1340, or 1540 is held by a clinician in a manner such as a person might hold the handle of a hammer, is the general configuration for handling guidewire management device 600, 700, 900, 1200, 1300, or 1500. When the clinician repositions their thumb over thumbwheel 642, 742, 942, 1242, 1342, or 1542, the second configuration is an operable configuration for advancing guidewire 102 out of or retracting guidewire 102 into guidewire management device 600, 700, 900, 1200, 1300, or 1500. Notwithstanding the above, some clinicians may find it comfortable to hold handle 640, 740, 940, 1240, 1340, or 1540 in a manner similar to that which a person might use to hold the barrel of a flashlight, thereby allowing access to both the first and second configurations with reduced hand movement.
[0047]
[0073] Handle 640, 1340, or 1540 has a channel 641, 1341, or 1541 configured to hold a conduit therein. As described below, the conduit may be, for example, guidewire conduit 1350 of guidewire management device 1300 or guidewire-casing conduit 1550 of guidewire management device 1500. Advantageously, this channel can hold the conduit in a coiled configuration, thereby allowing for packing of otherwise elongated conduits into a compact space. While only handles 640, 1340, and 1540 with channels are shown, any of handles 740, 940, and 1240 can have a channel configured to hold a conduit. Additionally, handle 640, 1340, or 1540 need not have channel 641, 1341, or 1541.
[0048]
[0074] Although there may be possible differences in one or more design elements, the first sleeves 910, 1210, 1310, or 1510 are similar to the first sleeves 110, 610, or 710 described above. Accordingly, the descriptions provided above for the first sleeves 110, 610, and 710 should be understood to extend to the first sleeves 910, 1210, 1310, and 1510 as if they were included in the descriptions of the first sleeves 110, 610, and 710.

[0075] Although there may be possible differences in one or more design elements, second sleeve 920, 1220, 1320, or 1520 is similar to second sleeve 120, 620, or 720 described above. Accordingly, the descriptions provided above for second sleeves 120, 620, and 720 should be understood to extend to second sleeves 920, 1220, 1320, and 1520 as if they were included in the descriptions of second sleeves 120, 620, and 720.
[0050]
[0076] The thumbwheel 642, 742, 942, 1242, 1342, or 1542 may be rotatably mounted on an axle fixedly coupled to each side of the handle 640, 740, 940, 1240, 1340, or 1540, such that the thumbwheel 642, 742, 942, 1242, 1342, or 1542 rotates relative to both the axle and the handle 640, 740, 940, 1240, 1340, or 1540. Alternatively, the thumbwheel 642, 742, 942, 1242, 1342, or 1542 can have an axle (e.g., as a single piece) or can be fixedly mounted on an axle that is further rotatably coupled to each side of the handle 640, 740, 940, 1240, 1340, or 1540, such that the combination of the thumbwheel 642, 742, 942, 1242, 1342, or 1542 and the axle rotates relative to the handle 640, 740, 940, 1240, 1340, or 1540. Thumbwheel 642, 742, 942, 1242, 1342, or 1542 is configured to assist in routing guidewire 102 distally through first sleeve 610, 710, 910, 1210, 1310, or 1510 and out of guidewire management device 600, 700, 900, 1200, 1300, or 1500. Thumbwheel 642, 742, 942, 1242, 1342, or 1542 is further configured to assist in routing guidewire 102 proximally through first sleeve 610, 710, 910, 1210, 1310, or 1510 and into guidewire management device 600, 700, 900, 1200, 1300, or 1500.
[0051]
[0077] Described below are methods for feeding or advancing guidewire 102 distally out of guidewire management device 600, 700, 900, 1200, 1300, or 1500. Further described below are methods for feeding or retracting guidewire 102 proximally into guidewire management device 600, 700, 900, 1200, 1300, or 1500.
[0052]
[0078] 9-12 to describe at least some of the unique features of guidewire management device 900 or 1200, guidewire management device 900 or 1200 has a first split sleeve 911 or 1211 formed within a distal portion of handle 940 or 1240.
[0053]
[0079] A first split sleeve 911 or 1211 separates from the first sleeve 910 or 1210 within the distal portion of the handle 940 or 1240. The first split sleeve 911 or 1211 is configured to have a lumen similar to the lumen of the first sleeve 110, 610, or 710 described above, and by extension, similar to the lumen of the first sleeve 910 or 1210. In effect, the lumen of the first split sleeve 911 or 1211 separates or branches from the lumen of the first sleeve 910 or 1210, thereby forming a branch lumen between the first sleeve 910 or 1210 and the first split sleeve 911 or 1211 within the distal portion of the handle 940 or 1240. The first sleeve 910 or 1210 is configured to at least route the guidewire 102 distally and out of the guidewire management device 900 or 1200, while the first split sleeve 911 or 1211 is configured to eject the splittable casing 904, which separates from the guidewire 102, while routing the guidewire 102 distally and out of the guidewire management device 900 or 1200. In effect, the branched lumens between the first sleeve 910 or 1210 and the first split sleeve 911 or 1211 are configured to facilitate the separation of the splittable casing 904 from the guidewire 102 while routing the guidewire 102 distally and out of the guidewire management device 900 or 1200.
[0054]
[0080] 12 to describe at least some of the unique features of guidewire management device 1200, guidewire management device 1200 has a flexible membrane 1206 that extends from a distal portion of guidewire management device 1200, over thumbwheel 1242, to a proximal portion of guidewire management device 1200. In practice, membrane 1206 may be coupled to a portion of a first sleeve 1210 in the distal portion of guidewire management device 1200 and a portion of a second sleeve 1220 in the proximal portion of guidewire management device 1200.
[0055]
[0081] Membrane 1206 is configured to route guidewire 102 distally out of guidewire management device 1200 or route guidewire 102 proximally into guidewire management device 1200. Membrane 1206 is sufficiently flexible to allow a middle portion of membrane 1206 to be pushed downward against a proximal portion of thumbwheel 1242 and move distally when thumbwheel 1242 is rotated, and to be released, in one or more additional steps described above, to return to the equilibrium state of membrane 1206. Similarly, membrane 1206 is sufficiently flexible to allow a middle portion of membrane 1206 to be pushed downward against a distal portion of thumbwheel 1242 and move proximally when thumbwheel 1242 is rotated, and to be released, in one or more additional steps described above, to return to the equilibrium state of membrane 1206.
[0056]
[0082] Membrane 1206 can have a low durometer, tackiness, or the like to facilitate gripping guidewire 102 or the combination of guidewires 102 within bag 104 or splittable casing 904 for the purpose of routing guidewire 102 distally out of guidewire management device 1200 or proximally into guidewire management device 1200. As shown in FIG. 12 , for example, the combination of guidewires 102 within splittable casing 904 is disposed between membrane 1206 and thumbwheel 1242 of guidewire management device 1200. When the middle portion of membrane 1206 is pressed downward against the proximal or distal portion of thumbwheel 1242, the combination of guidewires 102 within splittable casing 904 is also pressed downward against the proximal or distal portion of thumbwheel 1242. Then, when thumbwheel 1242 is rotated, the combination of guidewires 102 within splittable casing 904 is moved distally or proximally along with the intermediate portion of membrane 1206. Furthermore, when the intermediate portion of membrane 1206 is released, returning membrane 1206 to its equilibrium state, the combination of guidewires 102 within splittable casing 904 is also released. In this way, one or more of the above-described additional steps can advance guidewires 102 distally out of guidewire management device 1200 or advance guidewires 102 proximally into guidewire management device 1200.
[0057]
[0083] Referring to Figures 13 and 14 to describe at least some of the unique features of guidewire management device 1300, guidewire management device 1300 has a guidewire conduit 1350 coupled to second sleeve 1320 and a casing conduit 1354 coupled to both first split sleeve 1311 in the distal portion of handle 1340 and second split sleeve 1321 in the proximal portion of handle 1340.
[0058]
[0084] Although there may be possible differences in one or more design elements, the first split sleeve 1311 is similar to the first split sleeve 911 or 1211 described above. Accordingly, the descriptions provided above of the first split sleeves 911 and 1211 should be understood to extend to the first split sleeve 1311 as if the first split sleeve 1311 were included in the description of the first split sleeve 911 or 1211.
[0059]
[0085] A second split sleeve 1321 separates from the second sleeve 1320 within the distal portion of the handle 1340. The second split sleeve 1321 is configured to have a lumen similar to the lumen of the second sleeve 120, 620, or 720 described above, and by extension, similar to the lumen of the second sleeve 1320. In effect, the lumen of the second split sleeve 1321 separates or branches from the lumen of the second sleeve 1320, thereby forming a branch lumen between the second sleeve 1320 and the second split sleeve 1321 within the distal portion of the handle 1340. Similar to the channel 1341 of the handle 1340 configured to hold the guidewire conduit 1350 therein, the second split sleeve 1321 is configured to hold the casing conduit 1354 therein.
[0060]
[0086] As described above, thumbwheel 1342 is configured to assist in distally routing guidewire 102 through first sleeve 1310 and out of guidewire management device 1300. In cooperation with thumbwheel 1342, guidewire conduit 1350 is configured to distally route guidewire 102, or more specifically, guidewire 102 disposed within splittable casing 904, into second sleeve 1320. Guidewire conduit 1350 may be opaque or translucent, depending on the polymeric material selected. If guidewire conduit 1350 is translucent, guidewire conduit 1350 is configured to visualize guidewire 102 while routing guidewire 102 distally into second sleeve 1320. Additionally, casing conduit 1354 is configured to receive splittable casing 904 therein, which separates from guidewire 102 as it routes guidewire 102 distally and out of guidewire management device 1300. Similar to guidewire conduit 1350, casing conduit 1354 may be opaque or translucent, depending on the polymeric material selected. If casing conduit 1354 is translucent, casing conduit 1354 is configured to allow visualization of splittable casing 904 separating from guidewire 102 and into casing conduit 1354 as it routes guidewire 102 distally and out of guidewire management device 1300.
[0061]
[0087] As further described above, the thumbwheel 1342 is further configured to assist in routing the guidewire 102 proximally through the first sleeve 1310 and into the guidewire management device 1300. In cooperation with the thumbwheel 1342, the casing conduit 1354 is configured to route the splittable casing 904 into the first sleeve 1310, separating it from the guidewire 102 while routing the guidewire 102 distally and out of the guidewire management device 1300, and to route the guidewire 102 proximally for combination with the guidewire 102 as it enters the guidewire management device 1300. Again, the casing conduit 1354 can be opaque or translucent. If the casing conduit 1354 is translucent, the casing conduit 1354 is configured to visualize the splittable casing 904 while routing it proximally through the guidewire management device 1300 for combination with the guidewire 102. Guidewire conduit 1350 is configured to receive the combination of guidewire 102 and splittable casing 904 while advancing guidewire 102 proximally through guidewire management device 1300, and preferably, the guidewire 102 repositioned within splittable casing 940. Again, guidewire conduit 1350 may be opaque or translucent. If guidewire conduit 1350 is translucent, guidewire conduit 1350 is configured to allow visualization of the combination of guidewire 102 and splittable casing 904 while advancing guidewire 102 proximally through guidewire management device 1300.
[0062]
[0088] 15 and 16 to describe at least some of the unique features of guidewire management device 1500, guidewire management device 1500 has a guidewire-casing conduit 1550 coupled to both second sleeve 1520 and first split sleeve 1511 within a distal portion of handle 1540. Handle 1540 can have a channel 1541 configured to retain guidewire-casing conduit 1550 therein when guidewire-casing conduit 1550 is in a coiled configuration, such as the configuration shown.
[0063]
[0089] Although there may be possible differences in one or more design elements, the first split sleeve 1511 is similar to the first split sleeve 911 or 1211 described above. Accordingly, the descriptions provided above of the first split sleeves 911 and 1211 should be understood to extend to the first split sleeve 1511 as if the first split sleeve 1511 were included in the description of the first split sleeve 911 or 1211.
[0064]
[0090] As described above, the thumbwheel 1542 is configured to assist in distally routing the guidewire 102 through the first sleeve 1510 and out of the guidewire management device 1500. In cooperation with the thumbwheel 1542, the guidewire-casing conduit 1550 is configured to distally route the guidewire 102, or more specifically, the guidewire 102 disposed within the splittable casing 904, into the second sleeve 1520. The guidewire-casing conduit 1550 may be opaque or translucent, depending on the polymeric material selected. When the guidewire-casing conduit 1550 is translucent, the guidewire-casing conduit 1550 is configured to visualize the guidewire 102 while routing it distally into the second sleeve 1520. Additionally, guidewire-casing conduit 1550 is configured to receive splittable casing 904 therein, which separates from guidewire 102 as guidewire 102 is routed distally and out of guidewire management device 1500. The distal end of splittable casing 904, which separates from guidewire 102, is configured to track the bulbous end of guidewire 102 around guidewire-casing conduit 1550 as guidewire 102 is routed distally and out of guidewire management device 1500. In fact, if guidewire-casing conduit 1550 is translucent, guidewire-casing conduit 1550 is configured to visualize splittable casing 904 tracking the bulbous end of guidewire 102 around guidewire-casing conduit 1550 as guidewire 102 is routed distally and out of guidewire management device 1500.
[0065]
[0091] As further described above, the thumbwheel 1542 is further configured to assist in routing the guidewire 102 proximally through the first sleeve 1510 and into the guidewire management device 1500. In cooperation with the thumbwheel 1542, the guidewire-casing conduit 1550 is configured to route the splittable casing 904 into the first sleeve 1510 to separate from the guidewire 102 while routing the guidewire 102 distally and out of the guidewire management device 1500, so as to combine with the guidewire 102 as it is routed proximally into the guidewire management device 1500. Again, the guidewire-casing conduit 1550 may be opaque or translucent. If the guidewire-casing conduit 1550 is translucent, it is configured to allow visualization of the splittable casing 904 while advancing the splittable casing 904 proximally into the guidewire management device 1500 for combination with the guidewire 102. The guidewire-casing conduit 1550 is configured to receive the combination of the guidewire 102 and the splittable casing 904 therein while advancing the guidewire 102 proximally into the guidewire management device 1500, and preferably the guidewire 102 repositioned within the splittable casing 940. If the guidewire-casing conduit 1550 is translucent, it is configured to allow visualization of the combination of the guidewire 102 and the splittable casing 904 while advancing the guidewire 102 proximally into the guidewire management device 1500.
[0066]
[0092] 17 provides a side view of an assembly 1700 of guidewire management device 1500 coupled to a catheter assembly 1702, according to some embodiments. With the luer connectors of guidewire management device 1500 and catheter assembly 1720 coupled as shown, handle 1540 of guidewire management device 1500 allows for one-handed guidewire management while holding assembly 1700. method
[0093] The method of guidewire management device 100, 300, or 600 includes a connecting step of connecting the first sleeve 110 or 610 of guidewire management device 100, 300, or 600 to the hub of a medical device (e.g., a hollow needle) inserted into an insertion site of a patient.
[0067]
[0094] The method further includes an advancing step of advancing the guidewire 102 of the guidewire management device 100, 300, or 600 from the first sleeve 110 or 610, through the hub of the medical device, and into the insertion site of the patient. A seal (e.g., "O" ring 114 or 714) within the first sleeve 110 or 610 prevents fluid (e.g., air) from leaking from the guidewire management device 100, 300, or 600 as the guidewire 102 is advanced through the hub of the medical device and into the insertion site of the patient.
[0068]
[0095] The advancing step may include grasping the guidewire 102 within the sterile barrier 104 or 304 and manually advancing the guidewire 102 into the first sleeve 110. Such advancing may alternatively include pressing the guidewire 102 within the sterile barrier 104 against the thumbwheel 742 and rotating the thumbwheel 742 to advance the guidewire 102 into the first sleeve 610.
[0069]
[0096] In practice, guidewires 102 can be advanced into first sleeve 110 or 610 and out of guidewire management device 100 or 600 by picking up the combination of guidewires 102 within bag 104 or pressing guidewires 102 within bag 104 against thumbwheel 742, advancing guidewires 102 into first sleeve 110 manually or by turning thumbwheel 742, releasing the combination of guidewires 102 within bag 104, and repeating the above as needed. Guidewires 102 can be advanced into first sleeve 110 and out of guidewire management device 300 by picking up the combination of guidewires 102 within boot 304, manually advancing guidewires 102 into first sleeve 110, releasing the combination of guidewires 102 within boot 304, and repeating the above as needed.
[0070]
[0097] The method may further include a stopping step of stopping the advancement of guidewire 102 into the patient's insertion site when the bulbous end of guidewire 102 becomes trapped within narrowed portion 124 of bore 122 in second sleeve 120 of guidewire management device 100 or 300. Similarly, the stopping step may include stopping the advancement of guidewire 102 into the patient's insertion site when the bulbous end of guidewire 102 becomes trapped within recess 724 in second sleeve 620 of guidewire management device 600.
[0071]
[0098] The method further includes retracting the guidewire 102 from the insertion site in the patient, through the hub of the medical device, and into the first sleeve 110 or 610. A seal (e.g., "O" ring 114 or 714) within the first sleeve 110 or 610 prevents fluid (e.g., blood) from entering the guidewire management device 100, 300, or 600 as the guidewire 102 is retracted from the insertion site.
[0072]
[0099] In practice, guidewires 102 may be retracted into guidewire management device 100 or 600 through first sleeve 110 or 610 by picking up the combination of guidewires 102 within bag 104 or pressing guidewires 102 within bag 104 against thumbwheel 742, retracting guidewires 102 from first sleeve 110 manually or by turning thumbwheel 742, releasing the combination of guidewires 102 within bag 104, and repeating the above as needed. Guidewires 102 may be retracted into guidewire management device 300 through first sleeve 110 by picking up the combination of guidewires 102 within boot 304, manually retracting guidewires 102 from first sleeve 110, releasing the combination of guidewires 102 within boot 304, and repeating the above as needed.
[0073]
[0100] The method may further include stopping the retraction of the guidewire 102 from the patient's insertion site when the proximal or bulbous end of the guidewire 102 abuts a plug 152 within the proximal portion of the guidewire conduit 150 of the guidewire management device 100 or 300.
