Abstract
Surface metallized polymeric implants, such as cannula, needles, catheters, connectors and the like, a dry coating method therefor and apparatus to accomplish the same are disclosed. The metallization of the implants is intended to improve their biocompatibility and to reduce infusion-associated phlebitis and infection. The method essentially includes the dry coating of the outside surfaces of the polymeric implants with a metallic thin film. The apparatus to effect the dry coating method essentially includes a vacuum chamber, an evaporator and an ion source mounted in operative association within the chamber, and means for rotatably mounting a plurality of polymeric implants for exposure to the evaporator and the ion source.
