Abstract

A system for closing an opening in tissue includes a closure element having a coiled body and a plurality of tissue engaging portions disposed about at least a portion of the body, the body being formed of a resilient material. The system also includes a clip applier apparatus that is configured to deploy the closure element into the tissue.

Claims

1. A system for closing an opening in tissue, comprising:

a closure element having a coiled body and a plurality of tissue engaging portions disposed about at least a portion of said body, said body being formed of a resilient material; and

a clip applier apparatus being configured to deploy said closure element into the tissue.

2. The system of claim 1, wherein the clip applier apparatus includes a locator assembly having a distal end region configured to extend into the opening and selectably contact a wall of the tissue, said distal end region being selectively movable between and expanded state and unexpanded state.

3. The system of claim 1, wherein the clip applier apparatus includes a locator assembly having a distal end region and a proximal end region, the proximal end region being configured to cooperate with a movable plunger.

4. The system of claim 1, wherein the clip applier apparatus includes a carrier assembly, said carrier assembly retaining said closure element within said carrier assembly.

5. The system of claim 1, wherein the clip applier apparatus includes a triggering system, said triggering system being moveable toward a distal end of the clip applier apparatus.

6. A system for closing an opening in tissue, comprising:

a closure element having a coiled body and a plurality of tissue engaging portions disposed about at least a portion of said body, said body being formed of a resilient material; and

a clip applier apparatus being configured to deploy said closure element into the tissue, said clip applier apparatus comprising a housing supporting at least a portion of a locator assembly, a carrier assembly, and a triggering system.

7. The system of claim 6, wherein said locator assembly includes a distal end region configured to extend into the opening and selectably contact a wall of the tissue and a proximal end region configured to cooperate with a movable plunger.

8. The system of claim 6, wherein said carrier assembly is coupled with said locating assembly, said carrier assembly retaining said closure element within said carrier assembly.

9. The system of claim 6, wherein said triggering system cooperates with said locator assembly, said triggering system being moveable toward said distal end region of said locator assembly as a movable plunger moves toward said distal end region.

10. The system of claim 6, wherein said locator assembly is configured to selectively control a distal end region of said locator assembly between an expanded state and an unexpanded state.

11. A system for closing an opening in tissue, comprising:

a closure element having a coiled body and a plurality of tissue engaging portions disposed about at least a portion of said body, said body being formed of a resilient material; and

a clip applier apparatus being configured to deploy said closure element into the tissue, said clip applier apparatus including a locator assembly having a distal end region configured to extend into the opening and selectably contact a wall of the tissue and a proximal end configured to cooperate with a movable plunger, a carrier assembly coupled with said locating assembly, said carrier assembly retaining said closure element within said carrier assembly, and a triggering system cooperating with said locator assembly, said triggering system moveable toward said distal end region of said locator assembly as said movable plunger moves toward said distal end region.

12. The system of claim 11, further comprising a housing receiving said locator assembly, said carrier assembly, and said triggering system.

13. The system of claim 11, wherein said locator assembly is configured to selectively control said distal end region of said locator assembly between an expanded state and an unexpanded state.

14. The system of claim 13, wherein said locator assembly further comprises a control member coupled to at least one expansion member and a tubular member configured to surround said control member.

15. The system of claim 14, wherein said locator assembly further comprises a tubular body block mounted to said tubular member, a spring retainer receiving a portion of said tubular body block, and said movable plunger slidably cooperating with said tubular body block and said tubular member.

16. The system of claim 11, further comprising a splittable sheath selectively cooperating with said carrier assembly.

17. The system of claim 11, wherein said carrier assembly includes a pusher member, a carrier member, and a cover member.

18. The system of claim 17, wherein said carrier member includes a tapered distal end.

19. The system of claim 17, wherein said pusher member is moveable relative to said cover member and said cover member, said cover member being selectively deformable by distal movement of said pusher member.

20. The system of claim 19, further comprising a support member.
