Abstract

A suture anchor comprises an elongate body having a first end, a second end, and a longitudinal axis extending between the first and second ends. The first end may have a flared geometry. A lateral suture relief is in the elongate body extending from the first end to an longitudinal position intermediate the first and second ends. A hollow tubular portion in the elongate body is longitudinally spaced from the lateral suture relief. A suture is positioned in the hollow tubular portion. The suture has a delivery position parallel the longitudinal axis and a deployed position transverse to the longitudinal axis.

Claims

1. A suture anchor, comprising:

a) an elongate body comprising a first end, a second end, and a longitudinal axis extending between the first and second ends, the first end comprising a flared geometry;

b) a lateral suture relief in the elongate body, the relief extending from the first end to a longitudinal position intermediate the first and second ends;

c) a hollow tubular portion in the elongate body, the hollow tubular portion being longitudinally spaced from the lateral suture relief, and

d) a suture positioned in the hollow tubular portion, the suture having a delivery position parallel the longitudinal axis and a deployed position transverse to the longitudinal axis.

2. The suture anchor of claim 1, wherein the flared geometry comprises symmetrical wings.

3. The suture anchor of claim 1, wherein the suture is attached with a crimp.

4. The suture anchor of claim 3, further comprising teeth in the hollow tubular portion adjacent the location of the crimp.

5. The suture anchor of claim 1, wherein the first end further comprises a longitudinal rib.

6. The suture anchor of claim 5, wherein the first end has a generally W-shaped cross-section.

7. The suture anchor of claim 1, wherein the elongate body is formed by stamping a sheet of metal.

8. The suture anchor of claim 1, the second end comprises a geometry dimensioned to mate with the geometry of the first end.

9. The suture anchor of claim 1, wherein the suture is fixedly attached to the elongate body.

10. The suture anchor of claim 1, wherein the tubular portion has a substantially constant outside diameter.

11. The suture anchor of claim 10, wherein elongate body further comprises an intermediate portion between the tubular portion and the flared geometry, the intermediate portion having substantially the same outside diameter as the tubular portion and the suture relief extending onto the intermediate portion.

12. A anchor delivery device, comprising a flexible shaft having a distal end with a hollow needle for receiving the anchor of claim 1;

a push rod positioned in the flexible shaft adapted to deploy the anchor from the needle; and

a handle operatively connected to the flexible shaft and the push rod.

13. A suture anchor, comprising:

a) an anchor body stamped from a sheet of metal, the anchor body comprising a first end and a second end;

b) a lateral suture relief in the anchor body, the lateral suture relief extending from the first end to an longitudinal position intermediate the first and second ends;

c) a hollow portion in the anchor body, the hollow portion being longitudinally spaced from the lateral suture relief, and

d) a suture positioned in the hollow portion and fixedly attached to the anchor body.

14. The suture anchor of claim 13, wherein the hollow portion comprises a longitudinal seam.

15. The suture anchor of claim 14, wherein the seam comprises an offset stepped portion.

16. The suture anchor of claim 13, wherein the suture is fixedly attached with a crimp.

17. The suture anchor of claim 13, wherein anchor body comprises a flared geometry.

18. A suture anchor, comprising:

a) a first portion comprising a hollow tubular section with an outside diameter, a suture being positioned in the tubular section;

b) a second portion connected to the first portion, the second portion comprising a section with an outside diameter substantially the same as the first portion;

c) a third portion connected to the second portion, the third portion comprising a flared geometry spaced laterally outward relative the first portion; and

d) a lateral suture relief on the second and third portions.

19. The suture anchor of claim 18, wherein the tubular section is circular.
