ABSTRACT:
A concentric mating stent tissue heart valve which is capable of being assembled with a variety of tissue sources is provided. A tester for rapidly testing a tissue heart valve is provided comprising a substantially transparent viewing chamber having a plurality of size-specific mounts for mounting the valve within the chamber. The tester further comprises an element for displacing a volume of solution through the valve to test the opening and closing of the valve and to determine the amount of leakage through the valve when the valve is in a closed position.
