摘要

Disclosed herein is an artificial heart valve, comprising a valve housing comprising a distal plate and a proximal valve ring operably connected by a plurality of struts; one or more helical springs having a proximal end and a distal end; and a bellows spring having a proximal end, enclosed area, and a distal end, the distal end of the bellows spring operably attached to a first surface of a moving spring plate positioned axially in between the one or more helical springs and the bellows spring, the proximal end of the helical spring operably attached to a second surface of the moving spring plate; and a movable valve plate operably attached to the proximal end of the bellows spring, wherein the movable valve plate is configured to reversibly contact the proximal valve ring to create a seal and close the valve.
