Abstract
A valve replacement system that can be used for treating abnormalities of the right ventricular outflow tract in a nonsymmetrical region of a vessel or conduit that includes a prosthetic valve device and a foundation structure. The foundation structure contacts a portion of the inner wall of a vessel or conduit, and undergoes a shape change resulting in a corresponding change in the wall of the vessel or conduit. As a result, the lumen of the conduit is made symmetrical, and is complementary to the exterior surface of the stented valve, and thereby, improves the functioning of the valve. Another embodiment of the invention includes a method for replacing a pulmonary valve that includes forming a symmetrical region in a lumen of a conduit and placing a stented valve in the symmetrical region.
