Abstract
A knotless suture lock and bone anchor wherein a suture, looped through a tissue, is threaded through a plurality of body holes in the anchor to cinch the suture and tissue to the anchor without tying a suture knot on the tissue, and wherein the anchor is adapted for embedding in a bone. The tissue is secured to the anchor by suturing the tissue without a suture knot, fastening the standing leg portion of the suture on a suture leg-anchoring structure, and threading the working leg portion of the suture through the body holes. Pulling on the working leg portion of the suture tightens the suture on the body structure and cinches the loop without a suture knot on the tissue. The bone-embedding structure comprises a plurality of barbs adapted to resist pullout of the anchor from the bone.
