Abstract

The present disclosure relates to an anchor. The anchor includes an outer member including a body having an inner cavity, wherein the inner cavity includes a proximal portion configured for receipt of a delivery device and a distal portion having area of increased diameter. The anchor also includes an inner member coupled to the outer member, wherein the inner member includes a proximal portion having a projection configured for receipt in the area of increased diameter and a distal portion having a transverse through hole. A delivery device and method for tissue repair are also disclosed.

Claims

1. An anchor comprising

an outer member including a body having an inner cavity, the inner cavity including a proximal portion configured for receipt of a delivery device and a distal portion having an area of increased diameter;

and

an inner member coupled to the outer member, the inner member including a proximal portion having an angular projection configured for receipt in the area of increased diameter and a distal portion having a transverse through hole, wherein the outer member rotates relative to the inner member.

2. The anchor of claim 1 wherein the outer member includes threads on an outer surface of the outer member.

3. The anchor of claim 2 wherein the outer member includes longitudinal grooves on an outer surface of the member, the grooves extending partial length of the outer member.

4. The anchor of claim 1 wherein the proximal portion of the inner member includes an opening configured for receipt of a delivery device.

5. The anchor of claim 1 wherein the proximal portion of the inner member has a smaller diameter than the distal portion of the inner member.
