| 20080312748 | PROCESS FOR FORMING A CERAMIC LAYER - A process for forming a ceramic layer comprising a compound of a metal on a deposition surface of a workpiece comprises providing a reactive gas, selecting the amounts of a vapor of the metal and ions of the metal relative to each other, generating the metal vapor, and projecting an ion beam of the metal ions. The metal vapor, the metal ions, and the reactive gas form the ceramic layer with a desired structure. The process may include the step of controlling a deposition surface temperature. In one embodiment, the metal vapor comprises zirconium vapor and the ion beam comprises zirconium ions. The relative amounts of the zirconium vapor and the zirconium ions are selected to form a zirconia ceramic layer on the deposition surface. The zirconia may have multiple crystal phases that are formed according to a predetermined ratio. | 12-18-2008 |

The present invention also provides a method of repairing an articulating surface in a body using the inventive composition. The inventive hydrogel composition is created by blending two or more polymers to achieve the desired ratio of functional groups, reacting at least one polymer with a reagent that results in the formation of alcohol, acid, and/or amide functional groups of the desired ratio, and/or polymerizing at least one monomer to achieve the desired ratio of functional groups. | 07-09-2009 |

| 20090125115 | KNEE SYSTEM AND METHOD OF MAKING SAME - A femoral prosthesis may be formed as a femoral component incorporating a base material and an articulating material. In one exemplary embodiment, the base material is a metal and the articulating material is a polymer. Specifically, the base material provides strength and rigidity to the femoral component, while the articulating material contacts a tibial prosthesis or natural tibia during joint articulation. In one exemplary embodiment, the articulating material forms the articulating surface of one or more condyle portions of the femoral component. | 05-14-2009 |
| 20090192610 | ORTHOPEDIC 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 |
| 20090198286 | BONE FRACTURE FIXATION SYSTEM - A bone fracture fixation system comprising a metallic bone plate having a first composition comprising titanium or a titanium alloy and an opening for receiving a metallic fastener that has a second composition comprising titanium, a titanium alloy, or a stainless steel, and is sized to be received in the opening, and a cold-sprayed metallic coating either within the opening or on the metallic fastener is provided. The cold-sprayed metallic coating comprises a biocompatible metallic material having a third composition different than the first and second compositions. When the metallic fastener is inserted into the opening to stabilize a bone fracture, the cold-sprayed metallic coating may substantially prevent bonding or one or more types of corrosion between the metallic fastener and the metallic bone plate. In another embodiment, the cold-sprayed metallic coating comprises at least one of a cobalt-chrome alloy, gold, a gold alloy, silver or a silver alloy. | 08-06-2009 |

| 20110257757 | BI-MATERIAL PROSTHESIS COMPONENT - A prosthesis has prosthetic components principally comprising metallic materials, in which a portion of an articular interface between respective components is a metallic-nonmetallic interface. At least a portion of the articular surface of a femoral head may include a ceramic material defining an articulation zone, such as at a polar region of the femoral head, so that the ceramic articulates with a metallic acetabular liner. The area covered by the ceramic may be engineered to optimize the contact conditions between the femoral head and the acetabular liner, such as by providing two clearances therebetween. A relatively smaller, polar articulation clearance is defined by the gap between the ceramic coating and the metallic acetabular liner. A relatively larger, equatorial non-articulation clearance between the femoral head and the acetabular liner is defined by the gap between the portion of the femoral head not covered by the ceramic coating. | 10-20-2011 |
