摘要： An implant for interbody fusion of vertebrae comprising a unibody cage structure having an enveloping cage volume and a minimized material volume. The cage structure comprises a first and a second generally planar ring member, each ring member formed from an opposing pair of lengthwise joists and an opposing pair of cross joists, the joists together forming a large opening through the ring member. The ring members are fixedly sandwiched on a plurality of support members, the support members holding the ring members in a spaced apart relationship to thereby provide a large void volume relative to the enveloping cage volume, to thereby allow for receipt of a large volume of bone graft within the cage structure.

摘要： A femoral stem for canines or humans is made bone-compliant by use of a thick sintered titanium body in a proximal bone contacting region and a polymeric or ceramic body in a distal bone contacting region of the femoral stem. An elastic modulus is thereby engineered to match that of bone tissue. The porous sintered titanium body is created by sintering spheres of titanium. It is bonded to a central solid biocompatible metallic body by diffusion bonding. The distal region has a biocompatible polymeric body or biocompatible cement body. When compression molded the distal region develops an elastic modulus matching that of bone tissue. The proximal region has a porosity designed to encourage bone ingrowth.

摘要： An enhanced artificial disk for stabilizing a pair of adjacent vertebrae. The enhanced artificial disk include a disk and a stabilizer. The stabilizer includes a substantially keyhole shaped opening for receiving a stabilizer screw. By facilitating movement of the stabilizer screw within the opening, the enhanced artificial disk is capable of exhibiting a normal range of motion associated with a healthy disk while limiting any abnormal range of motion.

The coating layer structure comprises an outermost layer of a ceramic material. A bonding structure is deposited between the metal substrate and the coating layer structure. The bonding structure comprises a chromium rich layer, which is deposited onto the metal substrate surface and has a higher concentration of chromium than the metal substrate, as well as a gradient layer having a composition gradient from the chromium rich layer towards the surface of the device providing increasing proportions of a gradient material which has structural correspondence with the layer of the coating layer structure that is most adjacent to the bonding structure.
