Polymerbeschichtung fuer Prothesen, Implantate und Koerperelektroden und Verfahren zu ihrer Herstellung

A polymer coating on a prosthesis, implant or body electrode consists of a vinylidene fluoride/tri- or tetra-fluoroethylene copolymer (optionally as a composite with a polyacrylate, polystyrene and/or polycarbonate) and is characterised by being electrically polarised so as to impart piezoelectric properties. The polarisation process is preferably preceeded by heat treatment of the coating. USE - Specific claims refer to the production of dental prostheses, endo-prostheses (eg hip joints) and body electrodes (eg for heart pacemakers) with such a coating. ADVANTAGE - The coating is easily applied at low cost without the need for special techniques and is storage-stable. It shows high biocompatibility, has a high electro-stimulating effect, and shortens the healing time following implantation.
