METHOD FOR COATING A STENT

摘要

Method for applying a coating layer (7) to a tubular intraluminal implant (1), in particular to a vascular support (stent), wherein the surface of the implant (1) is interrupted by a large number of apertures (3), wherein the coating layer (7) is produced by deposition of material on the surface of the implant (1), wherein, in a first step, the implant (1) is pushed onto a cylindrical holder (4), wherein, in a second step, a sacrificial material (5), in particular copper, is deposited on the surface of the implant (1), until the deposited sacrificial material (5) fills the apertures (3), at least almost completely, wherein, in a third step, the coating layer (7) is deposited on the surface of the implant (1) provided with sacrificial material (5), and wherein, in a fourth step, the cylindrical holder (4) and the sacrificial material (5) located in the apertures (3) are removed.
