20120197407 | HIGHLY LUBRICATING SLIDING MEMBER AND ARTIFICAL JOINT USING SAME - Disclosed are: a sliding member which is capable of maintaining wear resistance over a long period of time; an artificial joint member in which the polymer base is reduced in thickness; and an artificial joint which exhibits high lubricating properties in the body, biocompatibility and resistance to dislocation. Specifically disclosed is a polymer sliding material which has a coating layer (B) that is composed of a graft polymer containing a phosphorylcholine group and having a density of at least 1.4 g/cm | 08-02-2012 |
20110106005 | DEVICE FOR CELL TRANSPLANTATION - The present invention provides a cell transplantation device which is capable of inserting cells for transplantation into a cell-deficient site without application of direct external force to the cells. The present invention discloses a cell transplantation device provided with a plate-type carrier with at least one pass-through hole formed on its side surface, a linear member to be threaded through the pass-through hole, and a pusher member which engages with the linear member that comes out from each exit of the pass-through holes. | 05-05-2011 |
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 |
