Abstract

A suture anchor (10) for securing soft tissue to bone including a body extending along a longitudinal axis between opposite ends, and at least one eyelet (12) extending between lateral surfaces of the body for receiving a suture. The eyelet (12) defines two entry/exit void regions (16) and a central void region (14) extending between the entry/exit void regions (16). Each entry/exit void region (16) extends from one of the lateral surfaces of the body and has an axis forming an acute angle with the longitudinal axis of the body. Each entry/exit void region (16) also has a surface comprising a segment of a conic surface extending about the axis of the entry/exit void region and tapering inward towards the longitudinal axis of the body. The central void region extends along an axis transverse to the longitudinal axis of the body.

3. A suture anchor according to claim 1, wherein the axis of each entry/exit void region extends within a plane formed by the longitudinal axis of the body and the axis of the central void region.
4. A suture anchor according to claim 3, wherein the axes of the entry/exit void regions extend at equal angles.
5. A suture anchor according to claim 4, wherein the axes of the entry/exit void regions extend at an angle of about sixty degrees with respect to the longitudinal axis of the body.
6. A suture anchor according to claim 1, wherein openings of the eyelet are elliptical.
7. A suture anchor according to claim 1, wherein the body includes a drive head at one of the ends and the eyelet is formed through the drive head.
8. A suture anchor according to claim 7, wherein the cross-section of the drive head is substantially rectangular.
9. A suture anchor according to claim 1, wherein the body includes cut-outs extending between openings of the eyelet and an end surface of the body.
10. A suture anchor according to claim 9, Wherein each of the cut-outs extends between corners formed by the end surface and the lateral surface of the body.
11. A suture anchor according to claim 1, wherein the surfaces of the entry/exit void regions each comprise a segment of a conic surface of about sixty degrees.
12. A suture anchor according to claim l, wherein the at least one eyelet comprises two eyelets.
13. A suture anchor according to claim 12, wherein the eyelets are substantially parallel.
