ABSTRACT:
An anatomically configured stent for a tanned, expanded natural tissue heart valve, a valve prosthesis including the stent, and a process for preparing the prosthesis are disclosed. The stent comprises a frame having three struts, two of which are biased radially inwardly and the third of which is also biased radially inwardly or generally parallel to the frame axis and a fabric cover covering at least the exterior of the frame, the cover having a bead along its perimeter that provides a site for attachment of the valve to the stent.
