PROSTHETIC VALVE WITH ASYMMETRIC LEAFLETS

Described embodiments are directed toward prosthetic valves having leaflets that move asymmetrically in that in the fully open position, the leaflet first side region opens less than the leaflet second side region. Asymmetric opening and final open position, in synchrony with the other leaflets having similar motion and final open position creates spiral flow exiting the open valve that may, among other things, increases blood flow on the downstream side of the leaflet and thus reduces stagnation of the blood that might lead to thrombus formation. Controlled asymmetric movement of the leaflet reduces closing volume by initiating closure on the leaflet first side region and finishing closures on the leaflet second side region.
