Abstract

The present disclosure relates to a composite anchor. The anchor includes a cannulated proximal portion having a threaded outer surface and a distal portion coupled to the proximal portion, the distal portion including a top portion, a bottom portion, and a through hole, wherein the top portion is configured to be disposed within the cannulation of the proximal portion.

Claims (23)

1. A composite anchor system comprising:

a composite anchor comprising:

a cannulated proximal portion comprising a threaded outer surface and inner surface;

a distal portion coupled to the proximal portion, the distal portion comprising a top portion, a bottom portion, and a through hole, wherein the top portion is configured to be disposed within the cannulation of the proximal portion;

wherein the top portion of the distal portion comprises at least two sides and a middle portion formed between the at least two sides;

wherein the through hole is positioned distal to the proximal portion, the through hole being in communication with the cannulation of the proximal portion via a channel adjacent to the middle portion; and

a driver configured to engage a substantial length of the inner surface of the proximal portion.

2. The anchor of claim 1 wherein the bottom portion is substantially cone-shaped.

3. The anchor of claim 1 , wherein the at least two sides are substantially trapezoid-shaped and the middle portion is substantially round.

4. The anchor of claim 1 wherein the anchor further comprises at least one suture disposed within the through hole and extending through the cannulation of the proximal portion.

5. The anchor of claim 1 wherein both the proximal portion and the distal portion include absorbable material.

6. The anchor of claim 1 wherein the proximal portion includes absorbable material and the distal portion includes non-absorbable material.

7. The anchor of claim 6 wherein the absorbable material includes a polymer material and the non-absorbable material includes a polymer material.

8. The anchor of claim 6 wherein the absorbable material includes a polymer material and the non-absorbable material includes a metal material.

9. The anchor of claim 1 wherein the proximal portion and the distal portion are coupled by way of an interference fit.

10. The anchor of claim 1 wherein the proximal portion and the distal portion are coupled by way of a sonic weld.

11. A composite anchor system comprising:

a composite anchor comprising:

an absorbable cannulated proximal portion comprising a threaded outer surface and inner surface;

a non-absorbable distal portion coupled to the absorbable cannulated proximal portion, the non-absorbable distal portion comprising a top portion, a bottom portion, and a through hole, wherein the top portion is configured to be disposed within the cannulation of the absorbable cannulated proximal portion;

wherein the top portion of the non-absorbable distal portion comprises at least two sides and a middle portion formed between the at least two sides;

wherein the through hole is positioned distal to the absorbable proximal portion, the through hole being in communication with the cannulation of the absorbable proximal portion via a channel adjacent to the middle portion; and

a driver configured to engage a substantial length of the inner surface of the absorbable cannulated proximal portion.
