Abstract

A suture anchor and kit for anchoring a suture member to human bone. A suture anchor includes a threaded portion and has a head at the proximal end thereof, the head being generally circular. A tip is located at a distal end of the shank. The shank is at least partially threaded and includes walls defining a reel portion. The shank also includes walls for engaging a suture, the walls for engaging the suture typically adjacent walls defining the reel portion. The head typically includes walls for engaging a drive tool. The kit includes a drive tool for rotating the suture anchor when a suture member is engaged with the walls for engaging the suture such that rotation of the anchor causes the suture material to wrap around the reel portion of the shank.

Claims

1. An anchor engageable with a tool for locating human tissue adjacent bone using a suture member engaged with the tissue, the device comprising:

a first portion defined by a head having a top surface and a first diameter, the first portion including a reel having a second diameter with at least one hole through the reel, the at least one hole capable of receiving a suture therethrough and lower walls defining a third diameter;

wherein the first and third diameter are greater than the second diameter; and

a second portion, the second portion integral with the first portion, the second portion having walls defining an upper diameter which is less than the third diameter, the second portion having a removed end defining a point, the second portion including helically wound threads for threading the anchor into the bone, with a suture member engaging a tissue and the reel such that threading the anchor into the bone winds the suture on the reel.

2. The anchor of claim 1 wherein the first portion includes tool engaging walls.

3. The anchor of claim 2 wherein the tool engaging walls include a cut-out in the top surface of the head.

4. The anchor of claim 3 wherein the cut-out is a polygon.

5. The anchor of claim 1 wherein the first and second portion are comprised of a bioabsorbable material.

6. A kit for attaching tissue adjacent bone using a suture member, the kit comprising:

an anchor, the anchor comprising a first portion defined by a head, the head having a top surface and a first diameter, a reel, the reel having a second diameter with at least one hole through the reel, the at least one hole capable of receiving a suture therethrough and lower walls defining a third diameter;

wherein the first and third diameter are greater than the second diameter; and

a second portion, the second portion integral with the first portion, the second portion having walls defining an upper diameter which is less than the third diameter, the second portion having a removed end defining a point, the second portion including helically wound threads for threading the anchor into the bone, with a suture member engaging a tissue and the reel such that threading the anchor into the bone winds the suture on the reel; and

a tool, the tool for engaging the anchor, to thread the anchor into a bone with the suture engaged with the anchor.

7. The kit of claim 6 wherein the first portion of the anchor includes tool engaging walls.

8. The kit of claim 7 wherein the tool engaging walls of the anchor include a cut-out in the top surface of the head.

9. The kit of claim 8 wherein the cut-out of the anchor is a polygon and wherein the tool has an end defining a polygon.

10. The kit of claim 6 wherein the anchor comprised a biodegradable material.
