The implant includes a fixture configured to be anchored in the recipient's skull, and a skin-penetrating abutment configured to interface with the fixture and to permit the abutment to be removably attached to the fixture to form a fixture-abutment assembly. In an embodiment, at least one anti-microbial surface forms one or more surfaces of the formed fixture-abutment assembly located in an interior of the formed fixture-abutment assembly when the fixture is removably attached to the abutment with an abutment screw. The interior is substantially isolated from a surrounding environment of the fixture-abutment assembly.11-11-2010
20090192610ORTHOPEDIC COMPONENT OF LOW STIFFNESS - An orthopedic component having multiple layers that are selected to provide an overall modulus that is substantially lower than the modulus of known orthopedic components to more closely approximate the modulus of the bone into which the orthopedic component is implanted. In one exemplary embodiment, the orthopedic component is an acetabular shell. For example, the acetabular shell may include an outer layer configured for securement to the natural acetabulum of a patient and an inner layer configured to receive an acetabular liner. The head of a femoral prosthesis articulates against the acetabular liner to replicate the function of a natural hip joint. Alternatively, the inner layer of the acetabular shell may act as an integral acetabular liner against which the head of the femoral prosthesis articulates.07-30-2009

20130150966BONE IMPLANT - A bone implant including a peg component for fixing the implant into a bone, a body component for abutment with a mating bone implant and a coupling to allow releasable connection between the peg component and the body component.06-13-2013
20120283833ARTICULAR CARTILAGE TREATMENT METHOD - The present invention provides an method to alleviate a deteriorated condition at an articular joint site and for repair of damaged cartilage the method including the steps of imaging for the presence of osteonecrosis in the underlying bone, forming a cylindrical plug comprising articular cartilage and osteonecrotic bone using an endoscopic trephine, inspecting the removed cylindrical plug and the joint site for additional articular cartilage and osteonecrotic bone, selectively debriding osteonecrotic bone material associated with the bone cavity to achieve desired vascular characteristics for receiving a prepared bone graft material within the bone cavity, and overlying the received bone graft material with cartilage tissue at the cartilage tissue receiving surface.11-08-2012
20120010709LOW TEMPERATURE ENCAPSULATE WELDING - A load-bearing medical implant is disclosed that includes a load-bearing structure with a cavity extending into the outer surface of the structure. The cavity accommodates a sensor that is held in a fixed position within the cavity by an encapsulant. The cavity is covered by a plate that is welded over the cavity in close proximity to the sensor and encapsulant to provide a seal over the cavity and the electronic component without causing thermal damage to the encapsulant or sensor despite the close proximity of the encapsulant and sensor to the welded areas of the plate and structure. Methods for encapsulating the sensor in the cavity, methods for encapsulating a wire bus leading from the sensor through a channel in the implant and methods for pulsed laser welding of weld plate over the sensor and encapsulant with thermal damage to either are disclosed.01-12-2012
20120029633SUPPORT STRUCTURE IMPLANT FOR A BONE CAVITY - A support structure implant for location within a bone cavity to support the bone which defines the cavity is formed from interlaced wires which extend from a first end of the structure towards an opposite second end. The wires are formed into loops at the first end of the structure. The structure includes a clip having a plurality of fingers which extend through the loops to control the spacing between the loops.02-02-2012
20120095558SYNTHETIC BONE GRAFTS CONSTRUCTED FROM CARBON FOAM MATERIALS - A porous, self-sustaining body useful as a scaffold for bone grafting is provided. The scaffold comprises a carbonaceous matrix comprising a continuous phase having a surface and defining a plurality of open spaces throughout the matrix. The internal and external surfaces of the matrix are coated with a layer or film selected from the group consisting of osteogenic materials, therapeutic agents, and combinations thereof. The porous body comprises organic materials and is substantially free of metals. Methods of making and using the porous self-sustaining body are also provided, along with kits for facilitating the same.04-19-2012
20130211523MULTI-PIECE MACHINE GRAFT SYSTEMS AND METHODS - Embodiments of the present invention encompass graft assemblies, and methods for their use and manufacture. An exemplary bone graft assembly includes first and second bone pieces having respective mating features which, when combined, define non-uniform press fit. Related embodiments encompass graft assemblies having enclosed or hidden mating features.08-15-2013
20130211522WEDGE SHAPED FRACTURE FIXATION DEVICES AND METHODS FOR USING THE SAME - Reduced bone fracture fixation devices and methods for using the same are provided. Aspects of the reduced bone fracture fixation devices include a body dimensioned to be positioned in a reduced bone fracture, wherein the body has a wedge shape configuration sufficient to exert a force on bone of the reduced bone fracture and maintain reduction of the reduced bone fracture. The devices, kits and methods of the invention find use in a variety of applications, such as in applications in which it is desired to repair a reduced bone fracture.08-15-2013
