Abstract
The present invention relates to a method for manufacturing an implant, in particular an intraluminal endoprosthesis, having a body containing metallic material, preferably iron. The following manufacturing method is provided for promotion of the anti-inflammatory effect of the implant: (i) providing the body of the implant; (ii) producing an at least partially closed pore structure in a portion of the structure of the implant body close to the surface; and (iii) incorporating NOX into the cavities of the pore structure. Also described is an implant manufactured in this manner.
Claims13
A method for manufacturing a vascular implant, having a body containing metallic material comprising the following steps:
- i) providing the body of the implant;
- ii) producing an at least partially closed pore structure in a portion of the structure of the implant body close to the surface, comprising a reducing step followed by an annealing step in an oxidizing atmosphere, wherein the pore structure comprises microscopic structures having a diameter of less than 1 μm;
- and
- iii) incorporating NOx into the cavities of the pore structure.
