Description

[0001] This application is a divisional application of the invention patent application with application date of March 21, 2018, application number 201880020527.7, and name “Flexible stabilizing member for clip applier”. Technical Field

[0002] The present invention relates generally to clip appliers and, more particularly, to a flexible stabilizing member for a clip applier. Background Art

[0003] Ligating tissue (e.g., blood vessels, lymph nodes, nerves, fallopian tubes, and cardiac tissue) is a common practice in many surgical procedures. This practice is accomplished by closing the blood vessels with surgical clips or suturing the blood vessels with surgical sutures. The use of surgical sutures requires complex manipulation of the needle and surgical sutures to form the knots required to secure the blood vessels. Such complex operations are very time-consuming and difficult to perform, especially in endoscopic surgical procedures characterized by limited space and / or visibility. In contrast, surgical clips are relatively faster and easier to apply. Accordingly, the use of surgical clips in endoscopic and open surgical procedures has shown a sharp increase. Summary of the invention

[0004] The inventors have recognized the need to improve one or more features of clip applicators and / or surgical clips, such as the stability of the surgical clip in the clip applier. Surgical clips are typically applied by a clip applier having a pair of opposing jaw members. Currently available clip appliers typically secure the surgical clip at two points of contact between the opposing jaw members and the foot members of the surgical clip. Two points of contact do not provide sufficient stability for the surgical clip, and the surgical clip may be undesirably moved relative to the clip applier or even fall out from between the jaw members during a surgical procedure. The methods and systems of the present invention are intended to alleviate or solve one or more of the above-mentioned problems and / or other problems in the prior art.

[0005] A first aspect of the present invention relates to a clip applier configured to apply a surgical clip to tissue. The clip applier may include a first jaw member and a second jaw member configured to engage a distal portion of a surgical clip. The first jaw member and the second jaw member may be configured to move relative to each other between an open configuration and a closed configuration. The clip applier may also include a stabilizing member having an end portion fixed to the first jaw member. The stabilizing member may be configured to engage a proximal portion of the surgical clip and compress from a first configuration when the first jaw member and the second jaw member are in an open configuration to a second configuration when the first jaw member and the second jaw member are in a closed configuration.

[0006] In some embodiments, the stabilizing member may include a first wall and a second wall extending from the stabilizing member and defining a cavity therebetween, the cavity being configured to accommodate a proximal portion of a surgical clip and reduce lateral movement of the surgical clip. In some embodiments, the stabilizing member may include an eyelet configured to accommodate a proximal portion of a surgical clip and reduce lateral movement of the surgical clip. In some embodiments, the stabilizing member may include at least one bend that facilitates compression of the stabilizing member when the first jaw member and the second jaw member are closed. In some embodiments, at least one of the first jaw member and the second jaw member may include a longitudinal channel configured to accommodate the stabilizing member when compressed. In some embodiments, the stabilizing member may include a second portion fixed to the second jaw member. In some embodiments, the clip applier may include a second stabilizing member having an end portion fixed to the second jaw member. The second stabilizing member may be configured to compress from a first configuration when the first jaw member and the second jaw member are in an open configuration to a second configuration when the first jaw member and the second jaw member are in a closed configuration. In some embodiments, the end portion of the stabilizing member may be fixed in the longitudinal channel of the first jaw member. In some embodiments, the end portion of the stabilizing member can be releasably fixed to the first jaw member. In some embodiments, the end portion of the stabilizing member can include a flared end configured to snap into the first jaw member. In some embodiments, the stabilizing member can include a spring element. In some embodiments, the stabilizing member can include a plastic element.

[0007] A second aspect of the present invention relates to a stabilizing member configured to be received between a first jaw member and a second jaw member of a clip applier and to engage a proximal portion of a surgical clip. The stabilizing member may include a first portion having a flared end configured to snap into the first jaw member and a second portion having a flared end configured to snap into the second jaw member. The stabilizing member may include at least one bend configured to facilitate compression of the stabilizing member when the first jaw member and the second jaw member are in a closed configuration, and an eyelet between the first portion and the second portion is configured to accommodate a proximal portion of a surgical clip and reduce lateral movement of the surgical clip.

[0008] In some embodiments, the stabilizing member may include a first wall and a second wall defining a cavity configured to accommodate a proximal portion of the surgical clip. In some embodiments, the at least one bend may include a first bend on a first side of the eyelet and a second bend on a second side of the eyelet. In some embodiments, the stabilizing member may include a spring element. In some embodiments, the stabilizing member may include a plastic element.

[0009] A third aspect of the present invention relates to a method of securing a surgical clip to a clip applier having a first jaw member and a second jaw member. The method may include: engaging a first end portion of a stabilizing member with the first jaw member, and engaging a second end portion of the stabilizing member with the second jaw member. The method may also include: accommodating the surgical clip between the first jaw member and the second jaw member, and securing the surgical clip to the clip applier with the stabilizing member.

[0010] In some embodiments, securing the surgical clip with the stabilizing member may include receiving a proximal portion of the surgical clip into an eyelet of the stabilizing member. In some embodiments, the method may include engaging a distal portion of a first foot member of the surgical clip with the first jaw member, and engaging a distal portion of a second foot member of the surgical clip with the second jaw member.

[0046] The same or similar reference numbers are used in the drawings and the following detailed description to refer to the same or similar parts. DETAILED DESCRIPTION

[0047] The present invention will now be described in conjunction with the accompanying drawings, in which like reference numerals may refer to like elements throughout. According to conventional practice, as used herein, the term "proximal portion" refers to a particular portion of a device or its component that is generally closer to a medical professional who operates or manipulates the device as used, while the term "distal portion" refers to a particular portion of a device or its component that is opposite to the proximal portion, unless otherwise specified herein.

[0048] The present invention generally relates to a flexible stabilizing member for a clip applier, which is configured to provide higher stability for a surgical clip disposed between a first jaw member and a second jaw member of the clip applier. The flexibility of the stabilizing member allows its length to be sufficient to stabilize the surgical clip in an open configuration and to allow compression during the closing of the first jaw member and the second jaw member of the clip applier. The stabilizing member can also be accommodated or nested in a longitudinal channel when one or both jaw members are in a closed configuration so that the stabilizing member does not interfere with the closing of the jaw members. In some embodiments, the stabilizing member can be fixed to only one of the first jaw member and the second jaw member, and in some embodiments, the stabilizing member can be fixed to both the first jaw member and the second jaw member. In some embodiments, the stabilizing member can be attached to the jaws in a releasable manner to facilitate replacement of components when damaged. In some embodiments, the stabilizing member can be fixed to the jaws to facilitate the manufacture of the clip applier. The stabilizing member can include an eyelet configured to accommodate a proximal portion of the surgical clip. The stabilizing member can be composed of a spring-based metal configured to provide a distal force to the surgical clip to keep the surgical clip in the clip applier so that the boss can be omitted. Alternatively, the stabilization component can be made from a more cost-effective ductile plastic.

[0049] Figure 1A to Figure 1BClip applier 100 is shown in an open configuration having stabilizing member 140 and loaded with surgical clip 200. As shown, clip applier 100 may have first jaw member 102 and second jaw member 104 pivotably coupled to hinge member 106. First jaw member 102 and second jaw member 104 may be configured to compress surgical clip 200 onto tissue, for example, to ligate a blood vessel.

[0050] The surgical clip 200 can have a first clamping foot member 202 and a second clamping foot member 204 pivotably connected to a hinge member 206. The first clamping foot member 202 can have a generally convex inner surface, a generally concave outer surface, and a tip member 208 on a distal portion. The second clamping foot member 204 can have a generally concave inner surface, a generally convex outer surface, and a hook member 210 on a distal portion. The hook member 210 can engage and bend around the tip member 208 while one or both of the first clamping foot member 202 and the second clamping foot member 204 pivot, straighten and / or lengthen. The tip member 208 can then be received in the hook member 210 to secure the surgical clip 200 in a locked configuration, further see U.S. Pat. No. 4,834,096, the disclosure of which is expressly incorporated herein in its entirety. Each of the first clamping foot member 202 and the second clamping foot member 204 can have one or more engagement members 212, 214 on a distal portion. The engagement members 212, 214 may include one or more angled surfaces formed by the clamping foot members 202, 204. Figure 1A to Figure 1B As shown, the engagement member 212 of the first clamping foot member 202 can include a distally facing notch at the tip member 208 forming a pair of angled surfaces, while the engagement member 214 of the second clamping foot member 204 can include a distally facing angled surface on the proximal outer surface of the hook member 210.

[0051] As further shown, the first jaw member 102 and the second jaw member 104 can include at least one engagement member 116 at the distal portion and a stabilizing member 140 proximal to the at least one engagement member 116. The first longitudinal channel 108 can extend through the interior of the first jaw member 102, dividing the first jaw member 102 into a pair of first extensions 110. The second longitudinal channel 112 can extend through the interior of the second jaw member 104, dividing the second jaw member 104 into a pair of second extensions 114. At least one engagement member 116 can be disposed within the interior of the first channel 108 and the second channel 112 and include an angled surface configured to engage the angled surfaces of the engagement members 212, 214 of the surgical clip 200. For example, the engagement member 116 of the first jaw member 102 can be received in a recess of the first clamping foot member 202, and the engagement member 116 of the second jaw member 104 can abut a distally facing surface of the second clamping foot member 204.

[0052] Stabilizing member 140 may have a first end portion 142 and a second end portion 144, wherein first end portion 142 is fixedly secured to first jaw member 102 within first channel 108 (e.g., by welding or bonding), and second end portion 144 is configured to engage a proximal portion of surgical clip 200. Stabilizing member 140 may be a spring element (e.g., spring steel) configured to provide a distal force to surgical clip 200, urging engagement members 212, 214 to engage engagement members 116 of clip applier 100. In this manner, surgical clip 200 may be secured in a clip applier without bosses thereon. Stabilizing member 140 may also include first and second longitudinal walls 146 on opposite sides of second end portion 144. Longitudinal walls 146 may define a cavity therein that accommodates a proximal portion (e.g., hinge member 206) of surgical clip 200 and aligns surgical clip 200 by reducing lateral movement of the proximal portion. As the first jaw member 102 and the second jaw member 104 close the surgical clip 200, the stabilizing member 140 can be compressed and / or pivoted proximally. For example, the pivoting, straightening, and / or elongation of the first and second jaw members 202, 204 can apply a proximal force to the stabilizing member 140 to cause the stabilizing member 140 to be compressed and / or pivoted proximally. As the stabilizing member 140 is engaged by the second jaw member 104, the stabilizing member 140 can be further compressed and / or pivoted proximally. As the first jaw member 102 and the second jaw member 104 approach and / or close, the stabilizing member 140 can be accommodated in the first channel 108 and / or the second channel 112. The compression and / or pivoting of the stabilizing member 140 can allow the surgical clip 200 to extend when it is closed and prevent the stabilizing member 140 from obstructing the closure of the first and second jaw members 102, 104. Figure 1A to Figure 1BAs shown, compression and / or pivoting of the stabilization member 140 may be facilitated by at least one approximately 180 degree bend 148. The stabilization member 140 may further include an additional bend 149 proximate the second end portion 144 to form a seat for the proximal portion of the surgical clip 200, providing additional vertical stability.

[0053] FIG. 2A to FIG. 2B Clip applier 300 is shown in an open configuration having first and second stabilizing members 340 and loaded with surgical clip 200. As shown, clip applier 300 may have first and second jaw members 302, 304 pivotably coupled to hinge member 306. First and second jaw members 302, 304 may be configured to compress surgical clip 200 onto tissue, for example, to ligate a blood vessel.

[0054] As further shown, the first jaw member 302 and the second jaw member 304 can include at least one engagement member 316 at the distal portion and first and second stabilizing members 340 at least proximal to the engagement member 316. The first longitudinal channel 308 can extend through the interior of the first jaw member 302, dividing the first jaw member 302 into a pair of first extensions 310. The second longitudinal channel 312 can extend through the interior of the second jaw member 304, dividing the second jaw member 304 into a pair of second extensions 314. At least one engagement member 316 can be positioned inside the first channel 308 and the second channel 312 and include an angled surface configured to engage the angled surfaces of the engagement members 212, 214 of the surgical clip 200. For example, the engagement member 316 of the first jaw member 302 can be received in a recess of the first clamping foot member 202, while the engagement member 316 of the second jaw member 304 can abut a distally facing surface of the second clamping foot member 204.

[0055] Each stabilizing member 340 can have a first end portion 342 and a second end portion 344, wherein the first end portion 342 is fixedly fixed to one of the first and second jaw members 302 within the corresponding longitudinal channel 312 (e.g., by welding or bonding), and the second end portion 344 is configured to engage the proximal portion (e.g., hinge member 206) of surgical clip 200. Stabilizing member 340 can be a spring element (e.g., spring steel) configured to provide a distal force to surgical clip 200, urging engagement members 212, 214 to engage engagement member 316 of clip applier 300. In this way, surgical clip 200 can be fixed in clip applier 300 without a boss thereon. As first jaw member 302 and second jaw member 304 close surgical clip 200, stabilizing member 340 can be compressed and / or pivoted proximally. The pivoting, straightening, and / or elongation of the first and second foot members 302, 304 can provide a proximal force to the stabilizing member 340 to compress and / or pivot the stabilizing member 340 proximally. As the stabilizing member 340 is engaged by the opposing jaw members 302, 304, and / or the stabilizing member 340, the stabilizing member 340 can be further compressed and / or pivoted proximally. As the first and second jaw members 302, 304 approach and / or close, the stabilizing member 340 can be accommodated in the first longitudinal channel 308 and / or the second longitudinal channel 312. The compression and / or pivoting of the stabilizing member 340 can allow the surgical clip 200 to extend when it is closed and prevent the stabilizing member 340 from obstructing the closure of the first and second jaw members 302, 304. The compression and / or pivoting of the stabilizing member 340 can also be facilitated by at least one bend 348 extending along substantially the entire length of the stabilizing member 340. Second end portion 344 may further include a rounded portion to increase the contact surface between stabilization member 340 when first jaw member 302 and second jaw member 304 are compressed. FIG. 2A to FIG. 2B As shown, the stabilization member 340 can be symmetrical, and the jaw members 302, 304 can receive a surgical clip in either orientation.

[0056] FIG. 3A to FIG. 3B Clip applier 400 is shown in an open configuration having stabilizing member 440 and loaded with surgical clip 200, and Figure 3C Stabilizing member 440 is shown. As shown, clip applier 400 can have first jaw member 402 and second jaw member 404 pivotably coupled to hinge member 406. First jaw member 402 and second jaw member 404 can be configured to compress surgical clip 200 onto tissue, for example, to ligate a blood vessel.

[0057] As further shown, the first jaw member 402 and the second jaw member 404 can include at least one recess 418 at the distal portion and at least one stabilizing member 440 proximal to the recess 418. The first longitudinal channel 408 can extend through the interior of the first jaw member 402, dividing the first jaw member 402 into a pair of first extensions 410. The second longitudinal channel 412 can extend through the interior of the second jaw member 404, dividing the second jaw member 404 into a pair of second extensions 414. Each extension 410, 414 can have a recess 418 configured to accommodate the opposing boss member 216, and each longitudinal channel 408, 412 can be configured to accommodate a portion of the surgical clip 200. Each of the first jaw member 402 and the second jaw member 404 can have an open distal end 415 that opens into the longitudinal channel 408, 412 to receive the stabilizing member 440.

[0058] The stabilizing member 440 may include a clamping foot member 441, the end portion 442 of which may be releasably secured to the first and second jaw members 402 within the respective longitudinal channels 408, 412. Figure 3C As shown, the end portion 442 can be expanded to have a split configuration in which the segments are separated by perforations and offset from each other. The segments of the end portion 442 can be configured to collapse when the end portion 442 is received in the open distal end 415, and the segments of the end portion 442 can expand to frictionally engage the longitudinal channels 408, 412 to releasably secure the stabilizing member 440 in the first jaw member 402 and the second jaw member 404. In this configuration, the stabilizing member 440 can be adjacent to the proximal walls of the longitudinal channels 408, 412. After use, the stabilizing member 440 can be removed, for example, by pulling the stabilizing member 440 distally out of the first jaw member 402 and the second jaw member 404. However, it is also conceivable that the end portion 442 can have a cylindrical configuration, such as FIG. 6A to FIG. 6B shown.

[0059] The foot member 441 can have a first bend 448 at its proximal end that bends distally to connect to the angled foot member 443. The angled foot member 443 can extend from the first bend 448 to a second bend 449 that bends proximally and attaches to the central portion 451. The bends 448, 449 can provide a generally "M"-shaped configuration for the stabilizing member 440. The bends 448, 449 can be living hinges that facilitate compression of the stabilizing member 440 as the first jaw member 402 and the second jaw member 404 close the surgical clip 200. As the first jaw member 302 and the second jaw member 304 are approximated and / or closed, the stabilizing member 440 can be accommodated in the first channel 408 and / or the second channel 412. The flexibility of the stabilizing member 440 can allow the surgical clip 200 to elongate as it is closed and prevent the stabilizing member 440 from obstructing the closure of the first jaw member 402 and the second jaw member 404.

[0060] The central portion 451 can be configured to receive and stabilize a proximal portion (e.g., hinge member 206) of the surgical clip 200. For example, the central portion 451 can have an eyelet 450 configured to receive a proximal portion of the surgical clip 200 and reduce lateral movement of the surgical clip 200. Additionally or alternatively, the central portion 451 can have a longitudinal wall 446 that forms a cavity therein that is configured to receive a proximal portion of the surgical clip 200. The longitudinal wall 446 can extend proximally from the central portion 451 of the stabilizing member 440 toward the hinge member 406. In this regard, the length and / or width of the longitudinal wall 446 can be greater than an immediately adjacent portion of the stabilizing member 440. The longitudinal wall 446 can extend along the proximal portion of the surgical clip 200 to improve stability.

[0061] Figure 4 A second embodiment of a surgical clip 200 loaded into a clip applier 400 is shown. As shown, the surgical clip 200 can include a tail or extension member 220 extending from a proximal portion of the surgical clip 200 that is configured to be received in an eyelet 450 of the stabilizing member 400. The extension member 220 can extend proximally from a proximal portion (e.g., hinge portion 206) and have a vertically curved hook portion. The width of the extension can be less than the width of the hinge portion 206 and / or the foot members 202, 204. The extension member 220 can facilitate loading the surgical clip 200 between the first jaw member 402 and the second jaw member 404 and into the eyelet 450 when the surgical clip 200 is in either orientation. Figure 4 The second embodiment of surgical clip 200 is shown loaded into clip applier 400, but the second embodiment of surgical clip 200 may be loaded into any number of other clip appliers, including other embodiments of the present invention.

[0062] like FIG. 5A to FIG. 5BAs shown, clip applier 400 may be assembled by receiving stabilization member 440 and / or surgical clip 200 from cartridge 500. Cartridge 500 may include first compartment 502 containing stabilization member 440 and / or one or more second compartments 504 containing at least one surgical clip 200. For example, cartridge 500 may include a single first compartment 502 and a plurality of second compartments 504 aligned along a longitudinal axis of cartridge 500. The number of second compartments 504 may be based on the surgical procedure being applied.

[0063] Further FIG. 5A to FIG. 5B As shown, a method of assembling clip applier 400 may include inserting first jaw member 402 and second jaw member 404 into first compartment 502. Stabilizing member 440 may be secured to first jaw member 402 and second jaw member 404 by receiving stabilizing member 440 into open distal end 415 of longitudinal passages 408, 412. The method may further include inserting jaw members 402, 404 into second compartment 404 to secure surgical clip 200 to jaw members 402, 404 and stabilizing member 440. For example, jaw members 402, 404 may receive boss 216 of surgical clip 200 in recess 418, and hinge member 206 of surgical clip 200 may be engaged by stabilizing member 440. Clip applier 400 may be configured to compress and / or lock loaded surgical clip 200 onto tissue. Clip applier 400 may then be loaded with a second surgical clip 200 using the same stabilizing member 440 to apply the second surgical clip 200 during the same procedure, such as to the same tissue. Stabilizing member 440 may be removed from clip applier 400 and / or discarded after the procedure.

[0064] Fig. 6A Clip applier 600 is shown in an open configuration having stabilizing member 640 and loaded with surgical clip 200, and Figure 6B Stabilizing member 640 is shown. As shown, clip applier 600 can have first jaw member 602 and second jaw member 604 pivotably coupled to a hinge (not shown). First jaw member 602 and second jaw member 604 can be configured to compress surgical clip 200 onto tissue, for example, to ligate a blood vessel.

[0065] As further shown, the first jaw member 602 and the second jaw member 604 can include at least one recess 618 at the distal portion and at least one stabilizing member 640 proximal to the recess 618. The first longitudinal channel 608 can extend through the interior of the first jaw member 602, dividing the first jaw member 602 into a pair of first extensions (not labeled). The second longitudinal channel 612 can extend through the interior of the second jaw member 604, dividing the second jaw member 604 into a pair of second extensions (not labeled). Each extension can have a recess 618 configured to accommodate the relative boss member 216, and each longitudinal channel 608, 612 can be configured to accommodate a portion of the surgical clip 200. Each jaw member in the first jaw member 602 and the second jaw member 604 can have an open distal end 615 that passes into the longitudinal channel 608, 612 to receive the stabilizing member 640.

[0066] The stabilizing member 640 may have a foot member 641, the end portion 642 of which may be releasably secured to the first jaw member 602 and the second jaw member 604 of the respective longitudinal channels 608, 612. The end portion 642 may be an enlarged cylindrical member extending perpendicularly from the foot member 641. For assembly, the end portion 642 may be passed through the open distal ends 615 of the first jaw member 602 and the second jaw member 604 and snapped into the recesses of the longitudinal channels 608, 612 to releasably secure the stabilizing member 640 in the first jaw member 602 and the second jaw member 604. After use, the stabilizing member 640 may be removed, for example, by pulling the stabilizing member 640 distally out of the first jaw member 602 and the second jaw member 604. However, it is also conceivable that the end portion 442 may have a split configuration, such as FIG. 3A to FIG. 3C shown.

[0067] The foot member 641 can have a bend 648 at its proximal end that bends distally to connect to the central portion 651. The bend 648 can have an obtuse angle and be a living hinge that facilitates compression of the stabilization member 640 as the first jaw member 602 and the second jaw member 604 close the surgical clip 200. For example, as the first jaw member 602 and the second jaw member 604 are approximated and / or closed, the stabilization member 640 can be received into the first channel 608 and / or the second channel 612. The flexibility of the stabilization member 640 can allow the surgical clip 200 to elongate as it is closed and prevent the stabilization member 640 from obstructing the closure of the first jaw member 602 and the second jaw member 604.

[0068] The central portion 651 can be configured to receive and stabilize the proximal portion (e.g., hinge member 206) of the surgical clip 200. For example, the central portion 651 can have an eyelet 650 configured to receive the proximal portion of the surgical clip 200 and reduce lateral movement of the surgical clip 200. Additionally or alternatively, the central portion 651 can have a wall 646 that forms a cavity therein that is configured to receive the proximal portion of the surgical clip 200. The wall 646 can extend laterally from the central portion 651 of the stabilization member 640.

[0069] Fig. 7A Clip applier 700 is shown in an open configuration with stabilizing member 740 and loaded with surgical clip 200, and Figure 7B Stabilizing member 740 is shown. As shown, clip applier 700 can have a first jaw member 702 and a second jaw member 704 pivotably coupled to a hinge (not shown). First jaw member 702 and second jaw member 704 can be configured to compress surgical clip 200 onto tissue, for example, to ligate a blood vessel.

[0070] As further shown, the first jaw member 702 and the second jaw member 704 can include at least one recess 718 at the distal portion and at least one stabilizing member 740 proximal to the recess 718. The first longitudinal channel 708 can extend through the interior of the first jaw member 702, dividing the first jaw member 702 into a pair of first extensions (not labeled). The second longitudinal channel 712 can extend through the interior of the second jaw member 704, dividing the second jaw member 704 into a pair of second extensions (not labeled). Each extension can have a recess 718 configured to accommodate the relative boss member 216, and each longitudinal channel 708, 712 can be configured to accommodate a portion of the surgical clip 200. Each jaw member in the first jaw member 702 and the second jaw member 704 can have an open distal end 715 that passes into the longitudinal channel 708, 712 to receive the stabilizing member 740.

[0071] The stabilizing member 740 may have a foot member 741, the end portion 742 of which may be releasably secured to the first jaw member 702 and the second jaw member 704 within the respective longitudinal channels 708, 712. The end portion 742 may be an enlarged cylindrical member extending perpendicularly from the foot member 741. For assembly, the end portion 742 may be received into the open end 715 and snapped into the recess of the longitudinal channels 708, 712 so that the stabilizing member 740 is releasably secured in the first jaw member 702 and the second jaw member 704. After use, the stabilizing member 740 may be removed, for example, by pulling the stabilizing member 740 distally out of the first jaw member 702 and the second jaw member 704. However, it is also conceivable that the end portion 742 may have a split configuration, such as FIG. 3A to FIG. 3C shown.

[0072] The foot member 741 can have a bend 748 along its length and be connected by a central portion 751 having a central bend 749. The bend 748 can substantially match the curvature of the second foot member 204. The bends 748, 749 can facilitate compression of the stabilizing member 740 as the first jaw member 702 and the second jaw member 704 close the surgical clip 200. For example, as the first jaw member 602 and the second jaw member 604 are approximated and / or closed, the stabilizing member 740 can be accommodated in the first channel 608 and / or the second channel 612. The flexibility of the stabilizing member 740 can allow the surgical clip 200 to elongate as it is closed and prevent the stabilizing member 740 from obstructing the closure of the first jaw member 702 and the second jaw member 704.

[0073] The central portion 751 can be configured to receive and stabilize the proximal portion (e.g., hinge member 206) of the surgical clip 200. For example, the central portion 751 can have a plurality of walls 746 that form a cavity therein that is configured to receive the proximal portion of the surgical clip 200. Figure 7B As shown, the central portion 751 can have first and second walls 746 positioned on either side of the eyelet 750. When the first jaw member 702 and the second jaw member 704 are in the open configuration, the walls 746 can engage the proximal portion of the surgical clip 200 without the proximal portion of the surgical clip 200 being received within the eyelet 750. However, the eyelet 750 can be configured to receive the proximal portion of the surgical clip 200 as desired. The walls 746 can extend longitudinally distally from the central portion 751 of the stabilizing member 740.

[0074] Fig. 8A Clip applier 800 is shown in an open configuration with stabilizing member 840 and loaded with surgical clip 200, and Figure 8B Stabilizing member 840 is shown. As shown, clip applier 800 can have a first jaw member 802 and a second jaw member 804 pivotably coupled to a hinge (not shown). First jaw member 802 and second jaw member 804 can be configured to compress surgical clip 200 onto tissue, for example, to ligate a blood vessel.

[0075] As further shown, the first jaw member 802 and the second jaw member 804 can include at least one recess 818 at the distal portion and at least one stabilizing member 840 proximal to the recess 818. The first longitudinal channel 808 can extend through the interior of the first jaw member 802, dividing the first jaw member 802 into a pair of first extensions (not labeled). The second longitudinal channel 812 can extend through the interior of the second jaw member 804, dividing the second jaw member 804 into a pair of second extensions (not labeled). Each extension can have a recess 818 configured to accommodate the relative boss member 216, and each longitudinal channel 808, 812 can be configured to accommodate a portion of the surgical clip 200. Each jaw member in the first jaw member 802 and the second jaw member 804 can have an open distal end 815 that passes into the longitudinal channel 808, 812 to receive the stabilizing member 840.

[0076] The stabilizing member 840 may have a foot member 841, the end portion 842 of which may be releasably secured to the first jaw member 802 and the second jaw member 804 within the respective longitudinal channels 808, 812. The end portion 842 may be an enlarged cylindrical member extending perpendicularly from the foot member 841. For assembly, the end portion 842 may be passed through the open distal ends 815 of the first jaw member 802 and the second jaw member 804 and snapped into the recesses of the longitudinal channels 808, 812 to releasably secure the stabilizing member 640 in the first jaw member 602 and the second jaw member 604. After use, the stabilizing member 840 may be removed, for example, by pulling the stabilizing member 840 distally out of the first jaw member 802 and the second jaw member 804. However, it is also conceivable that the end portion 842 may have a split configuration, such as FIG. 3A to FIG. 3C shown.

[0077] The foot member 841 can have a bend 848 connected to the central portion 851, and the foot member 841 can extend proximally from the bend 848. The bend 848 can be greater than 90 degrees. The bend 848 can be a living hinge that facilitates compression of the stabilizing member 840 as the first jaw member 802 and the second jaw member 804 close the surgical clip 200. For example, as the first jaw member 302 and the second jaw member 304 are approached and / or closed, the stabilizing member 840 can be accommodated in the first channel 808 and / or the second channel 812. The flexibility of the stabilizing member 840 can allow the surgical clip 200 to extend when it is closed and prevent the stabilizing member 840 from obstructing the closure of the first jaw member 802 and the second jaw member 804.

[0078] The central portion 851 can be configured to receive and stabilize the proximal portion (e.g., hinge member 206) of the surgical clip 200. For example, the central portion 851 can have an eyelet 850 configured to receive the proximal portion of the surgical clip 200 and reduce lateral movement of the surgical clip 200. Additionally or alternatively, the central portion 851 can have a wall 846 that forms a cavity therein that is configured to receive the proximal portion of the surgical clip 200. The wall 846 can extend laterally from the central portion 851 of the stabilizing member 840.

[0079] 9A to 9C Clip applier 900 is shown in an open configuration having a stabilizing member 940 and loaded with surgical clip 200. As shown, clip applier 900 may have a first jaw member 902 and a second jaw member 904 pivotably coupled to a hinge (not shown). First jaw member 902 and second jaw member 904 may be configured to compress surgical clip 200 onto tissue, for example, to ligate a blood vessel.

[0080] As further shown, the first jaw member 902 and the second jaw member 904 can include at least one recess 918 at the distal portion and at least one stabilizing member 940 proximal to the recess 918.

Each extension 910, 914 can have a recess 918 configured to accommodate the opposing boss member 216, and each longitudinal channel 908, 912 can be configured to accommodate a portion of the surgical clip 200. Each of the first jaw member 902 and the second jaw member 904 can have an open distal end 915 that opens into the longitudinal channel 908, 912 to receive the stabilizing member 940.

[0081] Stabilizing member 940 may be a spring element. Stabilizing member 940 may snap into first jaw member 902 and second jaw member 904 and apply a distal force to surgical clip 200 to hold surgical clip 200 between jaw members 1002, 1004. For example, each of first jaw member 902 and second jaw member 904 may include an opening 905 configured to releasably receive end portion 942 of stabilizing member 940. In this regard, stabilizing member 940 may be inserted between first member 902 and second member 904 in a compressed configuration through open end 915 and end portion 942 may be released to snap into opening 905. After use, stabilizing member 940 may be configured to be released by pressing end 942 to push stabilizing member 940 out of opening 905 so as to remove and / or discard the stabilizing member. Stabilizing member 940 can take the form of a single flat wire, the plane of which overlaps the proximal portion of surgical clip 200 to reduce lateral movement of surgical clip 200. For example, stabilizing member 1040 can have a substantially rectangular cross-section. The proximal portion of surgical clip 200 can be accommodated in one or more cavities or spaces formed between the opposite lateral planes of the wire. The bend 948 of wire 900 can also allow the flexible element to compress when clip applier 900 is compressed. Additional bends 949 can allow the wire to fit around the proximal portion of surgical clip 200. Stabilizing member 940 can also have a proximal support member 960 configured to apply a distal force to surgical clip 200 to help keep boss 212 in recess 918.

For example, each of first jaw member 1002 and second jaw member 1004 may include an opening 1005 configured to releasably receive end portion 1042 of stabilizing member 1040. In this regard, stabilizing member 1040 may be inserted into open distal end 1015 between first member 1002 and second member 1004 in a compressed configuration and end portion 1042 may be released to expand and snap into opening 1005. After use, stabilizing member 1040 may be released by pressing end 1042 to push stabilizing member 1040 out of opening 1005, and removed and / or discarded.

The bend 1048 of wire 1000 can also allow the flexible element to compress when clip applier 900 is compressed. The flat wire can be welded at the proximal end. Stabilizing member 1040 can also have a proximal support member 1060, which is configured to apply a distal force to surgical clip 200 to help keep boss 212 in recess 1018.

In this regard, stabilizing member 1140 can be inserted into the distal end of the opening in a compressed configuration and release terminal portion 1142 to expand and snap into opening 1005. After use, stabilizing member 1140 can be released by pressing terminal 1142 to push stabilizing member 1140 out of opening 1105 so as to remove and / or discard the stabilizing member. Stabilizing member 1140 can take the form of a monofilament extending between first jaw member 1102 and second jaw member 1104. Stabilizing member 1140 may include first and second longitudinal walls 1146, the cavities of which are configured to receive the proximal portion of surgical clip 200 and reduce lateral movement of surgical clip 200.
