Abstract: A Canine internal stifle stabilizing (CISS) system is provided as a three part modular, stifle stabilizing device that can be permanently or temporarily surgically implanted and attached onto the medial side of the distal femur and proximal tibia of quadrupeds. The stabilizing device is centered over the medial aspect of the quadruped stifle joint. The device includes three parts: a femoral component, a tibial component and an articular sliding insert component. The tibial and femoral components are fastened to the medial aspect of the femur and tibia by a varying number of fasteners. The distal end of the femoral component contains a ball and stem. The ball and stem is attached to the femoral component. The proximal tibial component has a rectangular space that accepts and holds the articular sliding insert component, such as by a pressure fit into the rectangular space provided on the proximal tibial component.

Abstract: Spinal implants are disclosed. One spinal implant includes a support body, an articulating element, a blocking member and a motion limiting member. The support body includes a superior end surface and a lower end surface having teeth. In between the superior end surface and the lower end surface is a recess formed in a sidewall of the support body for receiving the articulating element. The blocking member can be received in the recess to prevent inadvertent back-out of the articulating element from within the recess. The articulating element can articulate in one or more directions, thereby allowing articulation of the spinal implant into a desired position within a disc space.

Abstract: A biodegradable stent prosthesis formed from a degradable polymeric material, having a plurality of luminal, abluminal, and side surfaces, where at least some of the abluminal surfaces are concave and optionally the side surfaces are convex.

Abstract: An artificial heart valve comprises a support structure defining an aperture for blood flow and a flexible leaflet connected to the support structure along first and second at least partially straight lines of attachment, wherein the leaflet is movable relative to the support structure between an open configuration in which the leaflet permits blood flow through the aperture and a closed configuration in which the leaflet restricts blood flow through the aperture. A lateral cross-section taken through the leaflet defines an outwardly convex portion, an outwardly concave portion and a junction between the convex and concave portions. The heart valve may be configured for implantation in a human or animal subject. A method of manufacturing a heart valve and a former for use in such a method are also disclosed.

Abstract: Monoblock orthopedic and/or dental implants are disclosed. The monoblock implants include a ceramic articulating surface and an osseointegrative bone-contacting surface. Methods of making such implants also disclosed.

Abstract: An orthopaedic prosthesis for cementless fixation has a solid metal base and porous metal pegs extending out from the base. The pegs are mechanically, rather than metallurgically, fixed to the base. A process for making such a prosthesis is also disclosed.

Abstract: Methods and apparatus for orthopedic replacement of the hip through three incisions with a modular prosthetic system assembled in vivo while substantially preserving muscles and soft tissues around the hip joint resulting in reduced healing time and decreased risk of dislocation. A prosthetic femoral stem is inserted into the femur. A prosthetic femoral neck is inserted from a point along the side of the patient's body and into the side of the femur and through a lateral bore in the prosthetic femoral stem to join the prosthetic femoral head. The methods and apparatus include structures and techniques for fixing or enhancing interconnection of implant components, such as by increasing the interconnection in an interference fit with one or more tapers, threads, and/or cooling of components prior to assembly.

The wrist implant generally includes a radius portion, a carpal portion and a carpal ball. The wrist implant includes a primary articulation and a secondary rotational articulation. The primary articulation occurs between the radius portion and the carpal ball. The secondary articulation occurs between the carpal ball and the carpal portion.

Abstract: A modular joint prosthesis includes a nail for insertion into a bone marrow canal, the nail having a nail neck. A neck piece has a proximal end, a middle shaft portion defining a longitudinal axis, and a distal end with a conical pin to which a slip-on joint ball can be attached. The proximal end of the neck piece has a helmet-shaped receiving head that includes an insertion opening for insertion of the nail neck or a module connector, a slot extending in the direction of the longitudinal axis, and corresponding recesses positioned on either side of the slot and extending perpendicularly to the longitudinal axis. The corresponding recesses receive a tensioning means which, in a tensioned state, clampingly fixes the nail neck or the module connector in the receiving head by frictional engagement in a jaw-like manner by application of tightening torque sufficient to prevent axial displacement and rotation.

Abstract: A mosaic implant conformable to a curved surface, comprising first and second implant sections coupled along a beam portion extending across a length of the implant, each of the implant sections having a plurality of biocompatible mosaic plates, and a plurality of wires which interconnect the plates with one another. The mosaic implant is configured to be deformable such that at least a portion of the mosaic implant is conformable to a curved surface, with the beam portion providing structural support which resists inward deformation of the curved portion of the implant. A kit for forming a mosaic implant is also provided, along with a method for correcting a bone defect in a patient.

Abstract: A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.
