ABSTRACT:
A prosthetic heart valve which can be externally monitored is disclosed. In a first embodiment, the leaflets of the valve are magnetized, and the voltage induced in a coil juxtaposed thereto may be monitored. In a second embodiment, conductors are integrated with the leaflets. When the valve is then placed in a magnetic field, a voltage is induced in the conductors. The voltages induced in both valve configurations may be analyzed to indicate valve operation and conditions.
