Abstract
The development of a polymer membrane valve for artificial heart blood pumps is very much required, since the mechanical valves, such as the Björk-Shiley (BS) and Hall valves, used in the present artificial heart (AH) blood pumps have the following problems:
-
1.
A ring thrombus is often formed at the interface between the valve ring and pump housing, because these cannot be fixed seamlessly.
-
2.
Valve failure sometimes occurs at the disc and stent due to a water-hammer effect.
-
3.
Regurgitant and leakage flow generated in the mechanical valve induces hemolysis and the AH patient becomes mildly anemic.
-
4.
The valves are too expensive to popularize the AH as a therapeutic method.
