Abstract
A heart valve prosthesis includes a valve housing having an opening formed therein having an inmost arcuate surface and a leaflet pivotally mounted in the opening for movement between an open position and a closed position with the inmost arcuate surface. The leaflet has an outmost edge providing multiple points of contact with the housing. The leaflet also forms a leakage gap adjacent the leaflet major radius and between the inmost and outmost surfaces such that the multiple points of contact are displaced from the leaflet major radius and are adjacent to and on opposite sides of the leakage gap. One or several such leaflets may be provided in the housing. Each leaflet respectively includes the leakage gap and the adjacent multiple points of contact.
