MRT-compatible valve prosthesis for use in the human or animal body for replacement of an organ valve or a vessel valve
First Claim
1. A biological or artificial valve prosthesis for use in the human or animal body for the replacement of an organ valve or a vessel valve, particularly a cardiac valve prosthesis or a venous valve prosthesis, with a supporting valve framework, with at least one valve and with at least one conductor loop which forms the inductance of an electrical resonance circuit,wherein at least one conductor loop forms the valve framework and/or the valve or supporting areas of the valve framework and/or supporting areas of the valve,wherein at least two loops of the conductor loop be provided which form a cylindrical shape with their surfaces, enclose the natural valve shape and keep the outlets of the valve framework to the coronary arteries open in the area between the loops.

Abstract
The invention relates to a biological or artificial valve prosthesis (4, 5) for use in the human or animal body for replacement of an organ valve or a vessel valve, in particular a cardiac valve prosthesis or venous valve prosthesis, with a stent (8) or without a stent, with a supporting valve framework, with at least one valve (7) and with at least one conductor loop (2) that forms the inductance of an electrical resonance circuit. In order to provide a simple and inexpensive valve prosthesis that can be viewed in the MR imaging technique and is also easy to implant, the invention proposes that the at least one conductor loop (2) forms the valve framework and/or the valve (7) or supporting areas of the valve framework and/or supporting areas of the valve (7).
