  • Publication number: 20120041541
    Abstract: An implant, in particular an intraluminal endoprosthesis, having an implant body (2, 4) containing an aluminum compound, preferably an aluminum alloy and/or aluminum oxide. Improved biocompatibility of the implant is achieved in that at least the part of the surface of the implant body (2, 4) which is formed by the aluminum compound has a first layer (6) which contains an aluminum phosphate. Furthermore, a cost-effective method for producing such an implant is described.
