Abstract
Polymeric implants provided with coatings of bactericidal compounds in the form of ionized atoms by a vapor process. The polymeric implants include products designed to penetrate or enter the body, such as catheters, shunts connectors and the like. Coatings of bactericidal compounds on the polymeric implants are intended to make their use safe. The coatings are formed thereon in the form of ionized atoms of the compounds by ion-beam-assisted deposition in a vacuum chamber. The vacuum chamber is provided, inter alia, with an evaporator and an ion source mounted in operative association therein, including means for rotatably mounting a plurality of polymeric implants for exposure to the evaporator and the ion source.
