Abstract
The valve is positioned in the left ventricle drain line and includes a check valve which permits flow only away from the heart. A vent valve is located downstream of the check valve to prevent buildup of pressure. In addition, the valve includes an inwardly directed umbrella valve to limit left ventricle drain line vacuum intensity applied to the heart.
