Abstract

A surgical tool includes a shaft for receiving implants. The shaft defines a non-linear track. The tool includes a deployment member movable along the track to deploy the implants. An implant includes a body, and a plurality of alternating threads and flutes helically arranged about the body such that the body rotates under a linear applied force. Alternatively, an implant includes a body having a distal end for pound-in advancement into tissue. The body includes a plurality of cone-shaped, stacked barbs. A surgical tool includes two implants. The first implant has forward threads and the second implant has reverse threads. The first implant has threads for rotary advancement into tissue and the second implant is configured for pound-in advancement into tissue. The first and second implants are configured for pound-in advancement into tissue.

Claims

1. A surgical tool comprising:

a shaft for receiving implants, the shaft defining a non-linear track; and

a deployment member movable along the track to deploy the implants.

2. The surgical tool of claim 1 wherein the track comprises longitudinal and lateral sections.

3. The surgical tool of claim 1 wherein the deployment member comprises a nub received in the track.

4. The surgical tool of claim 3 wherein the deployment member comprises a handle and the nub extends from an inner surface of the handle.

5. The surgical tool of claim 1 wherein the deployment member comprises a pusher for engaging the implants.

6. The surgical tool of claim 5 wherein the shaft defines a lumen for receiving the pusher.

7. The surgical tool of claim 1 wherein the track defines a formation for releasably locking the deployment member.

8. The surgical tool of claim 7 wherein the formation comprises a concavity, and the deployment member includes a nub releasably received in the concavity.

9. The surgical tool of claim 1 wherein the shaft comprises a cylindrical member.

10. The surgical tool of claim 1 wherein the shaft defines a lumen for receiving the implants.

11. The surgical tool of claim 1 wherein the shaft comprises an adapter defining the track and a longitudinally extending member for receiving the implants.

12. The surgical tool of claim 11 further comprising a second shaft coupled to the adapter.

13. The surgical tool of claim 12 wherein the second shaft is positioned alongside the longitudinally extending member.

14. The surgical tool of claim 12 further comprising a hole forming member received by the second shaft.

15. The surgical tool of claim 14 further comprising a lever coupled to the hole forming member for distally advancing the hole forming member relative to the second shaft.

16. The surgical tool of claim 15 wherein the adapter defines a second track for receiving the lever.

17. The surgical tool of claim 14 further comprising a nub received in the track for advancing the hole forming member relative to the second shaft.

18. A surgical tool comprising:

implants;

a shaft for receiving the implants, the shaft defining a non-linear track; and

a deployment member movable along the track to selectively deploy the implants.

19. The surgical tool of claim 18 further comprising a spacer disposed between two implants.

20. A method comprising:

advancing a shaft to a surgical site, the shaft housing implants; and

moving a deployment member along a non-linear track defined by the shaft to deploy the implants into tissue at the surgical site.

21. An implant comprising:

a body; and

a plurality of alternating threads and flutes helically arranged about the body such that the body rotates under a linear applied force, each thread including multiple barbs.

22. The suture anchor of claim 21 wherein the body defines a longitudinal passage.

23. An implant comprising:

a body having a distal end for pound-in advancement into tissue, the body including a plurality of cone-shaped, stacked barbs, a diameter of an outermost region of the barbs increasing proximally.

24. The implant of claim 23 further comprising a proximal break-away hub.

25. A surgical tool comprising:

a first member;

a first implant coupled to the first member, the first implant having forward threads;

a second member coupled to the first member; and

a second implant coupled to the second member, the second implant having reverse threads.

26. The surgical tool of claim 25 further comprising a suture joining the first and second implants.

27. The surgical tool of claim 25 wherein the first member defines a lumen and the second member is received within the lumen.

28. The surgical tool of claim 25 further comprising a deployment element for advancing the second member relative to the first member.

29. A surgical tool comprising:

a first member;

a first implant coupled to the first member, the first implant having threads for rotary advancement into tissue;

a second member coupled to the first member; and

a second implant coupled to the second member, the second implant being configured for pound-in advancement into tissue.

30. The surgical tool of claim 29 further comprising a suture joining the first and second implants.

31. The surgical tool of claim 29 wherein the first member defines a lumen and the second member is received within the lumen.

32. The surgical tool of claim 29 further comprising a deployment element for advancing the second member relative to the first member.

33. A surgical tool comprising:

a first member;

a first implant coupled to the first member, the first implant being configured for pound-in advancement into tissue;

a second member coupled to the first member; and

a second implant coupled to the second member, the second implant being configured for pound-in advancement into tissue.

34. The surgical tool of claim 33 further comprising a suture joining the first and second implants.

35. The surgical tool of claim 33 wherein the first member defines a lumen and the second member is received within the lumen.

36. The surgical tool of claim 33 further comprising a deployment element for advancing the second member relative to the first member.
