20090306781 | High Wear-Resistant Bearing Material and Artificial Joint Replacement Using the Same - The present invention provides a bearing material that is excellent in durability and is capable of maintaining wear resistance over a long period of time. The bearing material of the present invention is a high wear-resistance bearing material | 12-10-2009 |
20100262237 | Biomaterial, Joint Prosthesis Using the Biomaterial and Method of Producing the Same - The object of the present invention is to provide a joint prosthesis, bearing material and a production method thereof, which suppresses wear in a sliding section and suppresses the production of abrasive powder even during repeated daily operation. To achieve the object, there is provided a biomaterial comprising: a substrate made of metal, alloy or ceramic; and a biocompatible material layer laminated on the substrate, wherein hydroxyl groups are formed on the substrate by surface-treating, while the biocompatible material layer comprises a polymer containing phosphorylcholine groups, the substrate and the biocompatible material layer are bound via a binder layer which is combined with the hydroxyl groups of the substrate and with the biocompatible material layer. | 10-14-2010 |
20110027757 | MEDICAL DEVICE AND METHOD FOR PRODUCING THE SAME - An object is to provide a medical device having excellent antithrombotic and sliding characteristics, which can exert a cell adhesion inhibitory effect. A medical device comprising: a substrate capable of forming hydroxyl groups; and a biocompatible material layer laminated on the substrate at an appropriate position, wherein the hydroxyl groups are formed on a surface of the substrate at least at a required position by a surface treatment, while the biocompatible material layer is formed from a polymer containing phosphorylcholine groups, and wherein the substrate and the biocompatible material layer are joined via a binder layer formed from silica being covalently bonded with the hydroxyl groups and the biocompatible material, respectively. | 02-03-2011 |
20110059176 | MATERIAL FOR PREVENTING TISSUE ADHESION AND MATERIAL FOR PREVENTING JOINT CONTRACTURE - The present invention provides a tissue adhesion prevention material preparable at an affected area at the time of surgical procedure by producing a three-dimensional polymeric structure having a flexible structure and high solute permeability in a medium comprising water as the main component under mild conditions appropriate for body tissue components (i.e., at ordinary temperature and pressure) without conducting a chemical reaction or employing a physical procedure such as heating or light or radiation irradiation. This makes it possible to provide a tissue adhesion prevention material and a joint contracture prevention materials, which can effectively prevent postoperative adhesion of a tissue in the affected area to the surrounding tissue and contracture of the movable part of a joint. | 03-10-2011 |
