ABSTRACT:
A suture anchor for approximating tissue to bone comprises an anchor member for securing the suture anchor to the bone and a plurality of sutures mounted to the anchor member so that the sutures extend outwardly from the anchor member. Each suture has a sharp pointed end for penetrating the tissue and a plurality of barbs which permit movement of the sutures through the tissue in one direction of movement of the pointed end and prevent movement of the sutures relative to the tissue in the opposite direction. The ends of the sutures are inserted and pushed through the tissue along a curvilinear path in a direction away from the bone. The sutures are drawn from exit points longitudinally spaced from the points of insertion and reinserted and advanced along a curvilinear path in the direction away from the bone. The sutures are drawn through the tissue while approximating the tissue adjacent the bone along the suture and leaving a length of the sutures in the tissue. The exit and entry points of two of the sutures are adjacent and the paths of the sutures substantially mirror one another.
