  • Patent number: 8337936
    Abstract: The present invention proposes a method for manufacturing an implant, in particular an intraluminal endoprosthesis, having a body such that the body has metallic material. To control the degradation in a desired time window, e.g., between four weeks and six months, the following production method is performed: a) preparing the body of the implant, and b) plasma-chemical treatment of at least a portion of the surface of the body in an aqueous solution by applying a plasma-generating electric alternating voltage to the body (5) of the implant, said voltage having a frequency of at least approximately 1 kHz, to create a first layer. The invention also relates to an implant obtainable by such a method.
