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. A system for tissue repair comprising:

a delivery device including;

an inner shaft including a proximal portion and a distal portion;

a first handle coupled to the proximal portion of the inner shaft;

an outer shaft slidably engaged with the inner shaft and including a proximal portion and a distal portion;

a second handle coupled to the proximal portion of the outer shaft;

an anchor including;

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

an inner member coupled to the outer member, the inner member including a proximal portion having a 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 system for tissue repair of claim 1 wherein the proximal portion of the inner member includes an opening configured for receipt of the inner shaft of the delivery device.
