Abstract
A method of manufacturing and testing a tissue heart valve during open heart surgery is disclosed. A piece of autologous tissue from the body of the patient is precisely cut according to the size of the open annulus remaining after excision of the patient's heart valve, with a plurality of holes being formed in the tissue. The tissue is situated between appropriately selected first and second stents so that the holes are registered with corresponding tissue alignment members in one of the stents, and the stents are positioned together to securely clamp the tissue therebetween. The constructed tissue heart valve is then mounted in a test chamber and visually inspected for leakage.
