ABSTRACT:
The invention concerns medical implants that are coated with biocompatible carbon-layers composed; the layers are prepd. by (a) at least partial covering or coating of a medical implant with a polymer film; (b) heating the polymer film to 2000-2500.degree.C in an oxygen-free atm. The medical device is prepd. from carbon, carbon-composite material, glass, ceramics, glass fibers, carbon fibers, metals, stainless steel, titanium, tantalum, platinum, nitinol, alloys, artificial bone, minerals, and their combinations; during heat treatment they are transferred in their heat-stable modifications. Artificial blood vessels, stents, coronary stents, peripheral stents, orthopedic implants, artificial hearts and heart valves, artificial bones and joints are prepd. Polymers are applied by conventional coating techniques, e.g. from polymer solns.; carbon and silicon can be deposited in a PVD or CVD process. The biocompatible carbon layer can be coated with a bioresorbant or biodegradable polymer layer, e.g. polylactide. The implants can be loaded with drugs, microorganisms or cells.
