Abstract

A suture anchor has a suture loop that is disposed internally within the suture anchor. The suture loop extends through a substantial length of the anchor body with the ends of the suture loop secured at the distal end of the anchor and the proximal end of the loop being flush with or recessed just below the proximal surface of the proximal end of the anchor. The anchor body is threaded and has a tapered distal portion. The proximal end portion of the suture anchor body has a hexagonally shaped opening to accept a hexagonal drive head. The peripheral surface defining hexagonally shaped opening is rounded and smooth to prevent abrading sutures placed in contact therewith.

Claims

1. A suture anchor comprising:

an anchor body having a central bore extending from an opening at the proximal end of the anchor body through a portion of the length thereof; and

a suture loop disposed in the central bore and having the ends thereof affixed in the anchor body.

2. The suture anchor according to claim 1, wherein the anchor body is made of a metal material.

3. The suture anchor according to claim 1, wherein the suture loop is slightly recessed from the proximal opening of the anchor body.

4. The suture anchor according to claim 1, wherein the anchor body includes two channels formed from the distal end of the central bore to two respective apertures formed near the distal end of the anchor body.

5. The suture anchor according to claim 4, wherein the ends of the suture loop are affixed to the anchor body at the apertures formed near the distal end thereof by a knot formed at each respective end of the suture loop.

6. The suture anchor according to claim 5, wherein the knots formed at the ends of the suture loop are secured with a biocompatible adhesive.

7. The suture anchor according to claim 4, wherein the anchor body is made of a metal material.

8. The suture anchor according to claim 7, wherein the ends of the suture loop are affixed to the anchor body at the apertures formed near the distal end thereof by crimping the anchor body to pinch the ends of the suture loop in the respective apertures.

9. The suture anchor according to claim 1, further comprising at least one strand of suture threaded through the suture loop.

10. The suture anchor according to claim 1, wherein the anchor body is tapered.

11. The suture anchor according to claim 10, wherein the anchor body is tapered to a substantially narrow point.

12. The suture anchor according to claim 11, wherein the anchor body is threaded.

13. The suture anchor according to claim 12, wherein the anchor body is self-tapping.

14. The suture anchor according to claim 1, wherein the anchor body is threaded.

15. The suture anchor according to claim 1, wherein the central bore has a cross-sectional shape so as to accommodate a driver head for driving the suture anchor.
