Abstract

The cardiac valve prosthesis comprises an outer ring (13) of tissue which is anchored to the heart itself. This ring supports a disc, the valve being a flat spiral coil (16) which has its outer end hinged (15) to the disc. In the closed position, the coil lies flat in the plane of the disc, being supported by parallel rods (17). When open a circular aperture (14) is provided, the central part of the coil contacting three equally spaced bent rods (18) which act as a cage limiting its movement.
