| 摘要 |
The present invention relates to a method for manufacturing an implant, in particular an intraluminal endoprosthesis, having a body containing metallic material, preferably iron. For controlling the degradation of the implant the method includes the following steps: (a) providing a first part of the implant body; and (b) performing heat treatment which alters the carbon content and/or the boron content and/or the nitrogen content in the structure of a near-surface boundary layer in the first part of the implant body in such a way that strain on the lattice or a lattice transformation, optionally following a subsequent mechanical load, is achieved in the near-surface boundary layer. Such an implant is also described.
