method of manufacturing a drug-eluting stent with a titanium oxide thin film coating

摘要

This invention relates to coated titanium dioxide or titanium dioxide thin film is doped with nitrogen to a metal stent , a titanium oxide relates to a method for producing a drug-eluting stent attaching the drug to the surface of the thin film layer . ; more specifically , the present invention is a metal stent as the dioxide in the blood vessel by PECVD (Plasma Enhanced Chemical Vapour Deposition) method coating a thin film of titanium or titanium dioxide doped with nitrogen , to modify the surface of the titanium oxide thin film with a hydroxy group is introduced into the low-temperature plasma method , antithrombotic agents or drugs such as excessive neointimal formation inhibitor chemically within the blood vessel by attaching relates to a method for producing a drug-eluting stent that delay drug release .
