Abstract

A one-piece suture anchor for anchoring a suture into a bone comprising an elongated body having proximal and distal ends, the body comprising at least one channel for receiving a suture, the channel comprising two elongated longitudinal guides continuing from the proximal end of the suture anchor towards the distal end of the anchor suture, wherein the guides are connected to each other by a section of channel that is configured such that it is not bent at any given point at an angle greater than or equal to ninety degrees.

Claims

1. A one-piece suture anchor for anchoring a suture into a bone comprising an elongated body having proximal and distal ends, said body comprising at least one channel for receiving a suture, said channel comprising two elongated longitudinal guides continuing from said proximal end of said suture anchor towards said distal end of said suture anchor, wherein said guides are connected to each other by a section of said channel that is not bent at any given point at an angle greater than or equal to ninety degrees and wherein said channel is contained within said body of said suture anchor, and further wherein said proximal end of said suture anchor has connecting means capable of connecting said suture anchor to a delivery device.

2. The suture anchor as claimed in claim 1, wherein said section of said channel connecting said guides is a continuous curve.

3. The suture anchor as claimed in claim 1, wherein said longitudinal guides and said section of said channel that connects said longitudinal guides comprise tunnels contained within said body of said suture anchor.

4. The suture anchor as claimed in claim 1, wherein said longitudinal guides comprise a groove formed on the surface of said suture anchor.

5. The suture anchor as claimed in claim 1, wherein said section of said channel that connects said longitudinal guides comprises a groove formed on the surface of said distal end of said suture anchor.

6. The suture anchor as claimed in claim 1, wherein said longitudinal guides and said section of said channel that connects said longitudinal guides comprise a grove formed on the surface of said suture anchor.

7. The suture anchor as claimed in claim 1, wherein said surface of said suture anchor comprise s a plurality of projections.

8. The suture anchor as claimed in claim 7, wherein said projections comprise screw thread.

9. The suture anchor as claimed in claim 1, wherein said proximal end of said suture anchor comprises an indentation for receiving a device for inserting said suture anchor.

10. The suture anchor as claimed in claim 1 wherein said suture anchor is biodegradable.
