Abstract

A threaded suture anchor useful in orthopedic rotator cuff repair surgical procedures.

Claims

1. A suture anchor, comprising:

an elongate root member having a proximal end and a distal end and an outer surface;

a plurality of thread flights extending out from the surface of the root member, said thread flights having a pitch and each said flight having a diameter, wherein the diameter of the thread flights decreased along the root member from the proximal end to the distal end;

a drill member extending distally from the distal end of the root member; and

,

a suture mounting member extending proximally from the proximal end of the root member.

2. The anchor of claim 1, wherein the root member has a circular cross-section.

4. The anchor of claim 1 wherein the pitch of the thread flights is constant.

5. The anchor of claim 1 wherein the pitch of the thread flights is variable.

6. The anchor of claim 1 wherein the drill member comprises a cylindrical member having a cutting flute therein.

7. The anchor of claim 1, wherein the thread flights are continuous.

8. The anchor of claim 1, wherein the thread flights are discontinuous.

9. The anchor of claim 1, further comprising a transverse suture mounting passage in the suture mounting member.

10. The anchor of claim 1, additionally comprising a suture mounting passage in the root member.

11. The anchor of claim 1, additionally comprising a surgical suture mounted thereto.

13. The method of claim 12, wherein the root member has a circular cross-section.

14. The method of claim 12, wherein the diameter of the root member varies from a maximum at the proximal end to a minimum at the distal end.

15. The method of claim 12, wherein the pitch of the thread flights is constant.

16. The method of claim 12, wherein the pitch of the thread flights is variable.

17. The method of claim 12, wherein the drill member comprises a cylindrical member having a cutting flute therein.

18. The method of claim 12, wherein the thread flights are continuous.

19. The anchor of claim 12, wherein the thread flights are discontinuous.

20. The method of claim 12, further comprising a transverse suture mounting passage in the suture mounting member.

21. The method of claim 12, additionally comprising a suture mounting passage in the root member.

22. The method of claim 12, additionally comprising a surgical suture mounted thereto.

23. The method of claim 12, wherein the soft tissue comprises the rotator cuff tendon and the bone comprises the humerus.

3. The anchor of claimn 2, wherein the diameter of the root member varies from a maximum at the proximal end to a minimum at the distal end.

12. A method of fastening soft tissue to bone, comprising:

providing a suture anchor comprising;

an elongate root member having a proximal end and a distal end and an outer surface;

a plurality of thread flights extending out from the surface of the root member, said thread flights having a pitch and each said flight having a diameter, wherein the diameter of the thread flights decreased along the root member from the proximal end to the distal end;

a drill member extending distally from the distal end of the root member;

a suture mounting member extending proximally from the proximal end of the root member; and

,

a surgical needle and suture mounted to the suture mounting member;

placing the drill member against an outer surface of a bone, and rotating the anchor such that the anchor is implanted in the bone; and

,

fastening soft tissue to the surface of the bone by engaging the soft tissue with the sutures.
