Abstract
A medical device provided with a subsurface bacteriostatic/bactericidal stratum to a predetermined depth is disclosed. The bacteriostatic/bactericidal stratum is introduced into the medical device by ion implantation of sufficient concentration to impart thereto the desired bacteriostatic/bactericidal property. The acquired bacteriostatic/bactericidal property has a useful life coterminal with the device. The treated medical device remains biocompatible, is non-leaching and, depending on the specific device, also is thromboresistant.
