Patent ID: 8167928

Claim:
A biological or artificial valve prosthesis for use in a human or animal body for the replacement of a valve, with a supporting valve framework, with at least one valve and with conductor loops forming the inductance of an electrical resonance circuit, wherein the conductor loops form solely the valve framework and are the only structure forming the framework and assuming a supporting function in the prosthesis, wherein the capacitance belonging to the resonant circuit is integrated into the design of the valve prosthesis, wherein the at least one conductor loop is at least partially coated with a nonconductor as a dielectric layer, wherein at least one internal capacitance is formed by the dielectric layer and the spacing between the loops of the conductor loops, and wherein the electrical resonance circuit generates a signal response, which is detectable and representable in a spatially resolved manner by means of at least one external reception coil, so that MR imaging of the valve and of its function is improved.
