ABSTRACT:
A Bileaflet Heart Valve where two leaflets open and close a cylindrical passageway through an annular body. An improved pivot for the leaflets uses a pair of generally triangular depressions in opposed supports that extend above the body. Each depression includes a curved edge bridging two straight edges that converge to a curved vertex. Elongated guides extend from opposite ends of each leaflet and define the pivotal axis. Each guide pivots on its rounded end in the region of the curved vertex as the leaflets open and close the passageway.
