Claim Text:
1. An artificial heart valve, comprising: a moveable valve ring that moves to a flat valve plate to form a seal valve; a flat contact area between the moveable valve ring and the flat valve plate, to minimize the force per unit area of contact between the moveable valve ring and the flat valve plate; and a bellows spring operably attached to the moveable valve ring, wherein the bellows spring is operably hung to a helical spring assembly, wherein an end of the helical spring assembly is operably attached to a cage housing, wherein the bellows spring has a first spring constant and the helical spring assembly has a second spring constant, the first spring constant and the second spring constant configured to assist in opening and closing of the valve, minimizing pressure and keeping movement gentle, wherein the bellows spring and the helical spring assembly are configured to isolate pressure on the valve, and substantially prevent high pressure forces from acting on the valve, wherein the bellows spring is suspended on the helical spring assembly, reducing the pressure on the valve, and wherein the valve is configured such that a flat valve plate force is effected substantially only by an area of the moveable valve ring that contacts the flat valve plate to seal the valve, minimizing the effect of blood pressure on valve pressure.
