Patent Summary

A cardiac implantation system comprises a catheter and a radially expandable valve prosthesis. The prosthesis includes an expandable annular support frame consisting of multiple longitudinally rigid, fixed-length support beams featuring bores. This frame is designed to be initially crimped for catheterization through a body duct and subsequently expanded at the target location. A tricuspid leafed-valve assembly, made of pericardium, is stitched to the support beams via thread or fiber through the bores. The assembly forms a conduit with an inlet and a tapered outlet featuring pliant, collapsible walls. The valve remains open during forward flow from inlet to outlet and collapses inwardly to block reverse flow.
