Endoprosthesis component

摘要

An endoprosthesis component and a method for producing an endoprosthesis component is disclosed. The endoprosthesis component comprises a body predefining the shape of the endoprosthesis component. On surface portions with which the endoprosthesis component in the implanted state is in contact with human tissue, the body is covered with an outer layer which comprises a nitride, an oxynitride or an oxide based on a refractory metal and which contains silver and/or copper. An intermediate layer is arranged between the outer layer and the body in such a way that parts of the intermediate layer are accessible from the outside. The endoprosthesis component enables generation of a long-term antimicrobial action with the outer layer and, in addition, action on the surrounding tissue from the intermediate layer.

主权项

1. An endoprosthesis component comprising:
a body; an outer layer covering the body on surface portions configured to come into contact with human tissue in an implanted state, wherein the outer layer consists of: a) a nitride based on a refractory metal, an oxynitride based on a refractory metal or an oxide based on a refractory metal, and b) one or more of silver and copper; and an intermediate layer arranged between the outer layer and the body, wherein parts of the intermediate layer are accessible to the human tissue in the implanted state.
