Abstract
A unidirectional flow heart valve includes a passageway having an inlet side and an outlet side. A disk occluder is disposed within the passageway. The disk occluder has a closed position wherein the disk occluder occludes fluid flow through the passageway and an open position wherein the disk occluder permits fluid flow through the passageway. A fulcrum causes the disk occluder to pivot off center between the open and closed positions. An electromagnetic control mechanism forces the disk occluder to remain closed when energized until a predetermined net pressure is reached against the disk occluder. When the electromagnetic control mechanism is either selectively deenergized or the force on the occluder disk is greater than the holding force of the electromagnetic control mechanism, the disk occluder is released from the closed position to pivot on the fulcrum in response to fluid pressure.
