ABSTRACT:
A substantially conical suture anchor having a bore in which an end of an insertion tool is inserted. The inserted end of the insertion tool is made of shape retaining material. The bore and base of the suture anchor are angled with respect to the central axis of the suture anchor and preferably are parallel to each other. During insertion, the suture anchor, mounted on the insertion tool, is reoriented to fit into the hole, thereby bending the shape memory end of the insertion tool. When the suture anchor is within cancellous bone tissue, the shape memory of the insertion tool urges the suture anchor to its original position (in which the suture anchor cannot fit through the bone hole). The suture anchor is thereby firmly anchored in the human bone.
