Abstract
A bileaflet mechanical cardiovascular valve having a generally annular valve body and two occluder leaflets mounted within the valve body such that the occluder leaflets will move back and forth between an open configuration wherein blood is permitted to flow through the annular valve body and a closed configuration wherein blood is prevented from flowing in at least one direction through the annular valve body. Slots formed in opposite ends of the occluder leaflets are mounted upon raised mounting members formed on the inner surface of the annular valve body to facilitate the opening and closing movement of the occluder leaflets.
