ABSTRACT:
A suture anchor is provided for approximating tissue to bone or other tissue. The suture anchor comprises an anchor member to fixedly engage the bone for securing the anchor member relative to the bone. A plurality of sutures are mounted to the proximal end of the anchor member so that the sutures extend outwardly from the anchor member. Each suture has a sharp pointed distal end for penetrating the tissue and a plurality of barbs extending from the periphery and disposed along the length of the body of the suture. The barbs permit movement of the sutures through the tissue in a direction of movement of the pointed end and prevent movement of the sutures relative to the tissue in a direction opposite the direction of movement of the pointed end. At least one pointed distal end of at least one suture comprises a needle.
