BILEAFLET MECHANICAL HEART VALVE HAVING ARROWHEAD SLOT HINGE CONFIGURATION

摘要

A bileaflet mechanical cardiovascular valve having a generally annular valve body (12) and two occluder leaflets (14) mounted within the valve body (12) such that the occluder leaflets (14) will move back and forth between an open configuration wherein blood is permitted to flow through the annular valve body (12) and a closed configuration wherein blood is prevented from flowing in at least one direction through the annular valve body (12). Slots (20) formed in opposite ends of the occluder leaflets (14) are mounted upon raised mounting members (18) formed on the inner surface of the annular valve body (12) to facilitate the opening and closing movement of the occluder leaflets (14).
