Abstract
A method for producing an implant, particularly an intraluminal endoprosthesis, having a body, wherein the body comprises magnesium or a magnesium alloy. In order to control the degradation in a desired time window, such as between four weeks and six months, the following production method is carried out: a) preparing the implant body, b) applying a metallic coating onto at least a portion of the body surface, the primary constituent of the coating being at least one element of the group containing titanium and aluminum, c) plasmachemical treatment of the portion of the body surface provided with the coating in an aqueous solution in order to produce a layer created by plasmachemical treatment by applying a mixed voltage generating the plasma to the body of the implant, wherein the mixed voltage has sufficient energy to temporarily ionize both the metallic coating and a subjacent region of the implant body. The invention further relates to an implant that can be obtained by such a method.
