Abstract

A clip applier may be configured to apply a surgical clip and have a pair of jaw members. Each of the jaw members may have an inner surface and a stabilizing member extending from the inner surface. Each of the jaw members may be configured to engage a distal portion of a leg member of the surgical clip. The stabilizing members may be configured to be positioned on opposite lateral sides of a proximal portion of the surgical clip to reduce lateral movement of the surgical clip. An inner portion of each of the stabilizing members may be spaced apart from the opposing jaw member in an open configuration, and each of the jaw members may have a channel on the inner surface to receive the opposing stabilizing member in a closed configuration.

First claim

What is claimed is:

1. A clip applier configured to apply a surgical clip, the clip applier comprising:
a first jaw member comprising a first inner surface and a first stabilizing member extending from the first inner surface, the first jaw member being configured to engage a distal portion of a first leg member of the surgical clip; and
a second jaw member comprising a second inner surface and a second stabilizing member extending from the second inner surface, the second jaw member being configured to engage a distal portion of a second leg member of the surgical clip,
wherein the first stabilizing member and the second stabilizing member are configured to be positioned on opposite lateral sides of a proximal portion of the surgical clip to reduce lateral movement of the surgical clip,
wherein the first jaw member has a first channel in the first inner surface, and the second jaw member has a second channel in the second inner surface,
wherein the first channel does not receive the second stabilizing member in an open configuration, and the first channel receives the second stabilizing member in a closed configuration, and
wherein the second channel does not receive the first stabilizing member in the open configuration, and the second channel receives the first stabilizing member in the closed configuration.

2. The clip applier of claim 1 , wherein an inner portion of the first stabilizing member is spaced apart from the second jaw member in an open configuration, and an inner portion of the second stabilizing member is spaced apart from the first jaw member in the open configuration.

3. The clip applier of claim 1 , wherein the first channel has a widened proximal portion configured to receive the second stabilizing member, and the second channel has a widened proximal portion configured to receive the first stabilizing member.

4. The clip applier of claim 1 , wherein the first stabilizing member comprises a first wall extending longitudinally along the first inner surface, the second stabilizing member comprises a second wall longitudinally extending along the second inner surface, and the first wall and the second wall are disposed on opposite lateral sides of a longitudinal axis of the clip applier.

5. The clip applier of claim 1 , wherein each of the first stabilizing member and the second stabilizing member comprises at least one substantially flat lateral surface.

6. The clip applier of claim 1 , wherein the first stabilizing member and the second stabilizing member extend substantially parallel in an open configuration and a closed configuration.

7. The clip applier of claim 1 , wherein the first stabilizing member and the second stabilizing member laterally overlap in a closed configuration.

8. The clip applier of claim 1 , wherein the first stabilizing member and the second stabilizing member do not laterally overlap in an open configuration.

9. The clip applier of claim 1 , wherein each of the first stabilizing member and the second stabilizing member has an inner portion defining an apex extending distally in an open configuration.

10. The clip applier of claim 1 , wherein the first inner surface comprises at least one first recess on a distal portion configured to receive a first boss on the first leg member of the surgical clip, and the second inner surface comprises at least one second recess on a distal portion configured to receive a second boss on the second leg member of the surgical clip.

11. The clip applier of claim 1 , wherein the first stabilizing member is integral to the first jaw member, and the second stabilizing member is integral to on the second jaw member.

12. The clip applier of claim 1 , wherein the first stabilizing member and the second stabilizing member are configured to not proximally contact a proximal end of the surgical clip in an open configuration.

13. A clip applier configured to apply a surgical clip, the clip applier comprising:
a first jaw member comprising a first inner surface and a first stabilizing member extending from the first inner surface, the first jaw member being configured to engage a distal portion of a first leg member of the surgical clip, and the first jaw member having a first channel in the first inner surface; and
a second jaw member comprising a second inner surface and a second stabilizing member extending from the second inner surface, the second jaw member being configured to engage a distal portion of a second leg member of the surgical clip, the second jaw member having a second channel in the second inner surface,
wherein the first stabilizing member and the second stabilizing member are configured to be positioned on opposite lateral sides of a proximal portion of the surgical clip to reduce lateral movement of the surgical clip,
wherein the first channel does not receive the second stabilizing member in an open configuration, and the first channel receives the second stabilizing member in a closed configuration,
wherein the second channel does not receive the first stabilizing member in the open configuration, and the second channel receives the first stabilizing member in the closed configuration, and
wherein the first stabilizing member and the second stabilizing member extend substantially parallel in the open configuration and the closed configuration.

14. The clip applier of claim 13 , wherein the first stabilizing member comprises a first wall extending longitudinally along the first inner surface, the second stabilizing member comprises a second wall longitudinally extending along the second inner surface, and the first wall and the second wall are disposed on opposite lateral sides of a longitudinal axis of the clip applier.

15. The clip applier of claim 13 , wherein the first stabilizing member and the second stabilizing member laterally overlap in the closed configuration.

16. The clip applier of claim 13 , wherein the first stabilizing member and the second stabilizing member do not laterally overlap in the open configuration.

17. The clip applier of claim 13 , wherein each of the first stabilizing member and the second stabilizing member have an inner portion defining an apex extending distally in the open configuration.

18. The clip applier of claim 13 , wherein the first stabilizing member and the second stabilizing member are configured to not proximally contact a proximal end of the surgical clip in the open configuration.
