摘要： A method for producing an implant, particularly an intralumimal 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.

摘要： The present invention relates to an implant, in particular an intraluminal endoprothesis, comprising a body containing a metallic material, and comprising at least one functional element that is fastened to the body and has a material composition in at least a portion of its volume that differs from the material of the body, the material composition preferably including radio-opaque and/or x-ray opaque material. To effectively prevent accelerated degradation due to the formation of a local cell of the material of the body and the functional element, the at least one functional element includes a first layer at least in the region of its surface where it is bonded to the body, the first layer primarily containing at least one metal oxide. Furthermore, the manufacture of an implant of this type is described.
