摘要： A method for producing a medical functional element having a self-supporting lattice structure which has interconnected webs. The method applies a first layer to the substrate layer, the first layer is structured by an etching process, the structured first layer is under-cut of a wet chemical etching process acting on the substrate layer, the substrate layer is removed in order to form the self-supporting lattice structure, a web constructional layer is applied to the first layer. The method is distinguished by the forming the first web attachment layer which has a smaller layer thickness than the web constructional layer and is intimately bonded to the web constructional layer in such a way that the web attachment layer, together with the web constructional layer, forms the webs of the self-supporting lattice structure.

摘要： Method for applying a coating layer to a tubular intraluminal implant, in particular to a vascular support (stent), where the surface of the implant is perforated by a plurality of apertures, and where the coating layer is produced by deposition of material onto the surface of the implant. The implant is first pushed onto a cylindrical holder 4, a sacrificial material, in particular copper, is then deposited onto the surface of the implant until the deposited sacrificial material almost entirely fills the apertures, the coating layer is then deposited onto the surface of the implant provided with sacrificial material, and then the cylindrical holder 4 and the sacrificial material situated in the apertures 3 are removed.
