Abstract
An implant, in particular an intraluminal endoprosthesis, is provided having an implant body containing biodegradable metallic material, preferably iron. To accelerate the degradation, at least a portion of the surface of the implant body has a first coating formed from a composition containing at least one element selected from the group including strontium and calcium. An inexpensive method for manufacturing such an implant is also described.
Claims15
A method for manufacturing an implant, in particular an intraluminal endoprosthesis, having an implant body containing biodegradable iron, comprising the following steps:
- a) providing the implant body;
- b) coating the implant body with a composition containing at least one element selected from the group consisting of strontium and calcium, whereby the coating in step b) is carried out by deposition from a gas phase;
- and
- c) implanting nitrogen ions in the coated implant body.
A method for manufacturing an implant, in particular an intraluminal endoprosthesis, having an implant body containing biodegradable iron, comprising the following steps:
- a) providing the implant body;
- b) coating the implant body with a composition containing at least one element selected from the group consisting of strontium and calcium, whereby the coating in step b) is carried out by deposition from a gas phase;
- and
- c) applying a coating containing an acid-degradable polymer to the coated implant body.
A method for manufacturing an implant, in particular an intraluminal endoprosthesis, having an implant body containing biodegradable iron, comprising the following steps:
- a) providing the implant body;
- and
- b) coating the implant body with a composition containing strontium, whereby the coating in step b) is carried out by deposition from a gas phase.
