Abstract
A suture anchor is described having a central shaft and at least one outwardly extending longitudinal rib. The ribs may have bone engaging elements such as threads or barbs on their outer surfaces. A bone boring tool having more than one set of sharpened cutting edges is described which creates a non-circular hole in bone approximating the anchor cross section geometry. The suture anchor is inserted into the shaped hole in bone and is rotated about its axis by the driver to engage the ribs with the bone.
Claims3
A suture anchor injection molded of a biocompatible body absorbable polymer comprising a central body having a length and provided with at least one outwardly extending longitudinal anchor rib, the at least one anchor rib being discontinuous over the length of the central body, the central body having a through-hole for receiving a suture, a distal end, and a proximal end adapted to be engaged and rotated by an insertion tool.
A suture anchor injection molded of a biocompatible body absorbable polymer, the suture anchor comprising:
- a central body provided with at least two outwardly extending longitudinal anchor ribs, the anchor ribs being of varied lengths and positions about the central body, the central body having a through-hole for receiving a suture, a distal end and a proximal end adapted to be engaged and rotated by an insertion tool.
A suture anchor injection molded of a biocompatible body absorbable polymer, the suture anchor comprising:
- a central body provided with at least one outwardly extending longitudinal anchor rib, the at least one anchor rib extending linearly along the central body, the central body having a through-hole for receiving a suture, a distal end and a proximal end adapted to be engaged and rotated by an insertion tool.
