Abstract: A shape-memory device manufactured from shape memory material includes multiple activation temperatures. The multiple activation temperatures arise from either the heat treatment of the device during manufacturing, or by combining different elements with different activation temperatures. To manufacture a shape-memory device with multiple activation temperatures, it is formed into a first shape. A first portion of the shape-memory device is heated to a first temperature, and a second portion of the shape-memory device is heated to a second temperature. The shape-memory device is then worked into a second shape. Accordingly, the first portion has a first transition temperature, and the second portion has a second transition temperature. In use, the shape-memory device is placed into a desired position. Energy is applied such that the first portion, second portion, or both portions are transformed.

Abstract: An anchor for fixing a ligament or tendon replacement in a bore formed in a bone has two parts. A first partially cylindrical part has a semi-circular bore therethrough extending along an axis. The bore tapers conically inwardly with respect to the axis from a larger radius at a first end to a smaller radius at second end. The outer surface of the partially cylindrical part is spaced at a constant radius from the axis between the first and second ends. The first and second parts have side walls formed between the bore and the outer surface which walls extend along a plane which forms an angle with respect to the central axis. When the two parts are engaged along their side wails and slide with respect to the axis the outer diameter of the two parts enlarges.

Abstract: Medical implants are formed at least in part from porous metal wherein the pores of the metal are filled with a hardenable material. The hardenable material can be used to assist in the manufacture of the implant, permitting detailed machining of the implant. Further, the hardenable material can be a resorbable material that strengthens the implant during implantation but is resorbed, once implanted, to permit bone growth and infiltration. Further, in an alternate embodiment, the hardenable material can be a thermoplastic material that can be heated by ultrasonic energy to create an adhesive bond between a fastener and bone structure.

Abstract: The present invention is an apparatus for suspending a soft tissue near a bone opening, which includes a bone anchor, a soft tissue anchor, a spacer, and a depth stop. The device of the present invention allows soft tissues to change positions and be held until sufficient healing has occurred.

Abstract: The present invention is directed generally to a biomedical system(s) and method(s). More specifically, some embodiments may include system(s) and method(s) used in medical treatment(s). Various embodiments may include medical system(s) and method(s) that may use an anchoring mechanism and screw (bolt, etc.) arrangement that increases the strength of attachment. Some embodiments may further include, for example, an anchoring mechanism that expands upon insertion of a screw (bolt, etc.) into an opening. Some embodiments may include, for example, a system(s) and method(s) for improvement of structural tissue (e.g., bone, cartilage) fixation and safety. Further, some embodiments may also include, for example, an anchoring mechanism and screw (bolt, etc.) system that may be utilized in orthopedic procedures. Still some embodiments may further include system(s) and method(s) providing improved screw fixation and enhanced stabilization in structural tissue or fracture repair.
