WEDGE SHAPED SUTURE ANCHOR AND METHOD OF IMPLANTATION

摘要

This invention is a suture anchor (300A) having an annular displaced corner and abutment wall which act to seat the suture anchor firmly within a bore hole in substrate (601). Application means are also disclosed which hold the suture anchor on a frangible shaft for insertion and upon completion of the insertion permit fracture of the frangible portion and removal of the instrument. In another embodiment the suture anchor comprises a substantially wedge-shaped body having a smaller distal end and a larger proximal end, means (330A) thereon for retaining a suture (500), and means thereon for releasable connection to an inserter shaft; a boundary surface and a plow surface of the body intersecting to form a biting edge at the proximal end of the body; and the boundary surface and an abutment surface of the body intersecting to form a cam surface at the proximal end of the body.
