ABSTRACT:
The disclosed prosthesis for replacement of the bicuspid or mitral valve in the left auriculo-ventricular aperture, or of the tricuspid valve in the right auriculo-ventricular aperture, is fitted to a semi-rigid ellipsoidal and reniform support which imitates the biological shape of the original organ. The moving part of the valve is fashioned from a single piece of biological, bio-compatible or polymeric material, and fabricated such that the sub-valve section is supported by two "suspenders" in order to ensure a singularly biological type of operation, with no drop in pressure incurred during the opening movement, and with minimal regurgitation during the closing movement.
