Knotless suture anchor
First Claim
1. A suture anchor comprising a shell and an anchor member:
- the shell comprising a body having a distal end, a proximal end and sidewalls therebetween defining an axial cannulation therethrough;
the anchor member comprising a body having a distal end and a proximal end, the anchor member body being sized to fit within the cannulation of the shell;
the sidewalls defining a lateral cut-out such that with the anchor member received within the cannulation a first lateral portion of the anchor member protrudes laterally out of the shell and a second, laterally opposite, lateral portion of the anchor member is enclosed by the sidewalls;
an exterior threading about the anchor member body, engaged with a complimentary internal threading on an interior surface of the sidewall;
the exterior threading creating a friction enhancement on the first lateral portion frictionally engageable with a bone surface through the lateral cut-out when the suture anchor is disposed within a bone tunnel defined by the bone surface.

Abstract
A suture anchor comprises a shell and an anchor member. The shell comprises a body having a distal end, a proximal end and sidewalls therebetween defining an axial cannulation therethrough. The anchor member comprises a body having a distal end and a proximal end which is sized to fit within the cannulation. The sidewalls define a lateral cut-out such that with the anchor member received within the cannulation a first lateral portion of the anchor member is exposed laterally and a second, laterally opposite, lateral portion of the anchor member is enclosed by the sidewalls. A friction enhancement on the first lateral portion frictionally engages a bone surface when the suture anchor is disposed within a bone tunnel defined by the bone surface. Suture is trapped between the shell and the anchor and also between the anchor and the bone surface.
