Abstract: A suture anchor apparatus comprising: an anchoring member made from a metal-based material and comprising a generally elongated body having a proximal end and a distal end, wherein an outer surface of the anchoring member defines a threading that winds around the body in a plurality of turns disposed along a longitudinal axis of the body; wherein the threading has a depth of about 1 mm and a pitch of about 3 mm, and an eyelet disposed near the distal end and penetrating transversely through the body.

Abstract: A method for repairing a ligament or tendon, the method comprising: passing one or more sutures through and/or around each respective end of a completely or partially torn ligament or tendon; placing a generally cylindrical hollow body or ring over the respective ends of the completely or partially torn ligament or tendon; passing the one or more sutures through the generally cylindrical hollow body or ring; and tying the one or more sutures around or through the generally cylindrical hollow body or ring wherein the sutures are secured in place around or through the generally cylindrical hollow body or ring via one or more notches or holes defined by the generally cylindrical hollow body or ring.

Abstract: An internal fixation plate for bridging two portions of a broken bone is formed to have properties in terms of bending, axial, and torsional stiffness suitable for those of the bone being mended. These properties include high resistance to bending and torsional stresses, and relatively low axial stiffness. One plate configuration which has been determined to have the desired stiffness properties is formed from a hollow tube deformed to have an external configuration substantial the same as conventional bone fixation plates. Arrangements are provided for precluding bone ingrowth, and this may be achieved by filling the member with a medically inert substance, such as silicone rubber or ultra high molecular weight polyethylene, or by sealing the openings into the tubular plate. The materials of the bone fixation plate may be selected for their mechanical properties, and also as biologically inert substances which will not have adverse physiological effects when embedded in the human body.

These properties include high resistance to bending and torsional stresses, and relatively low axial stiffness. One plate configuration which has been determined to have the desired stiffness properties is an elongated flat hollow metal plate or tube. Arrangements are provided for precluding bone ingrowth, and this may be achieved by filling the member with a medically inert substance, such as silicone rubber or ultra high molecular weight polyethylene, or by sealing the openings into the tubular plate. The materials of the bone fixation plate may be selected for their mechanical properties, and also as biologically inert substances which will not have adverse physiological effects when embedded in the human body.
