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 11 wherein the proximal portion of the inner member includes an opening configured for receipt of the inner shaft of the delivery device.

3. A method of tissue repair comprising:

inserting a first anchor into bone, the first anchor having a flexible member coupled thereto;

passing the ends of the flexible member through the tissue;

providing a second anchor comprising 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 a 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;

passing the ends of the flexible member through the through hole of the of the second anchor; and

advancing the second anchor into bone via both axial and rotary advancement.
