ABSTRACT:
A prosthetic valve for replacing a cardiac valve includes an expandable support member and at least two valve leaflets made of a first layer of biological material selected from peritoneal tissue, pleural tissue or pericardial tissue. A second layer of biological material is attached to the support member. The second layer is also made from peritoneal tissue, pleural tissue or pericardial tissue. The second layer includes a radially inwardly facing surface that defines a conduit for directing blood flow. The valve leaflets extend across the conduit to permit unidirectional flow of blood through the conduit. Methods for making and implanting the prosthetic valve are also provided.
