Abstract
Abstract The coating of carbonaceous material (16a, 17a; 21a) is applied by cathode sputtering with the use of a target constituted essentially of carbon. Preferred application for the manufacture of cardiac valve prostheses (15) and vascular prostheses (20) including substrates of polymeric material.
