Abstract: An apparatus for securing soft tissues, tendons and ligaments to bone using a suture strand. The apparatus includes a spear member which is able to pierce and securely engage the bone. The spear member includes an eyelet which is able to carry the suture strand at a position along the midportion of the suture strand. The suture strand is secured to the bone upon engagement between the spear member and the bone. In addition, the ends of the suture strand are accessible to the surgeon so that they may be manipulated so as to secure the soft tissue to the bone.

Abstract: An apparatus for removing tissue from a surgical site during a surgical procedure. The apparatus includes an abrading element for abrading the tissue during the surgical procedure. The abrading element has an abrading surface and at least one aperture disposed on the abrading surface. The apparatus also includes a shaft for supporting the abrading element during the surgical procedure as well as to permit rotation of the abrading element.

Abstract: A biocompatible implant for forming a barrier within a cavity formed in living tissue, the living tissue being at a first thermochemical state. The biocompatible implant includes a main body which is able to be inserted into the cavity. The biocompatible implant further includes a flange for securing the main body in a substantially stationary position within the cavity. The flange is relatively rigid at the first thermochemical state but is relatively deformable at a second thermochemical state.

Abstract: A modular hip prosthesis operable to engage the cortical material in a host femur having a metaphysis and an intramedullary canal. The modular hip prosthesis includes a modular metaphyseal segment which is able to be inserted into the metaphysis of the host femur. The modular metaphyseal segment includes an axial cone portion and a cervical cone portion. The modular hip prosthesis further includes a modular diaphyseal segment which is able to be inserted into the intramedullary canal and being removably secured to the modular metaphyseal segment. Finally, the modular hip prosthesis includes a modular head which is able to engage the modular metaphyseal segment and is detached from the modular diaphyseal segment.Also disclosed is surgical instrumentation for use in implanting a medical device. The surgical instrumentation includes a template having a plurality of scaled markings disposed thereon.

Abstract: A thermal packaging unit for a biocompatible implant. The thermal packaging unit includes a first compartment for storing the biocompatible implant. In addition, the thermal packaging unit further includes a second compartment which is operable to contain a chemical composition which is able to heat the biocompatible implant by means of an exothermic reaction.

Abstract: An acetabular cup prosthesis assembly has an outer shell, a bearing insert, a locking collar, and a locking ring. The bearing insert is retained within the outer shell, which has a generally smooth, hemispherical outer surface. The bearing insert is adapted to receive the femoral head of a hip prosthesis. An opening of the insert has a first diameter which is smaller than the diameter of the femoral head, and is elastically expandable to a second diameter to allow for passage of the femoral head through the opening. The locking collar is movable from a disengaged position to an engaged position adjacent the bearing insert to prevent the opening from expanding to the second diameter so as to lock the femoral head in position within the insert. The locking ring is disposed within a first circumferential groove in the inner surface of the outer shell, and serves to maintain the locking collar in position adjacent the bearing insert.
