Title:

DEVICE FOR REMOVING AN ENDOPROSTHESIS OR AN IMPLANT THAT IS IMPLANTED IN THE BODY AND IS MADE OF A SYNTHETIC MATERIAL

Document Type and Number:

WIPO Patent Application WO2007087800

Kind Code:

A9

Abstract:

The invention relates to devices for removing an endoprosthesis (1) or an implant which is implanted in the body and is made of a synthetic material. The inventive devices and methods are characterized especially by the fact that a minimal amount of tissue (4) decomposes such that the endoprosthesis or the implant can be removed gently, the endoprosthesis, the implant, or a section thereof embodying a conductor. The endoprosthesis or the implant and at least one electrode (2) that is connected in an electrically conducting manner to a surface area of the endoprosthesis of the implant, or at least one electrode which is in contact with a region of the material surrounding the endoprosthesis or the implant, are connected to an HF generator (3) as an AC current source in order to separate the endoprosthesis or the implant from material surrounding the same in such a way that power is applied to the tissue and/or the biomaterial that surrounds the endoprosthesis or the implant. The endoprosthesis or the implant is coupled to an apparatus in order to be removed.
