Abstract: A prosthesis includes a tubular graft, a prosthetic valve component, an inflow stent, an outflow stent, and a plurality of body stents disposed between the inflow and outflow stents. Each stent is a sinusoidal patterned radially-expandable ring having a first set of crowns and a second set of crowns, with the first set of crowns disposed closer to an inflow end of the tubular graft than the second set of crowns. The prosthesis is configured to be resistant to backfolding and/or buckling during deployment thereof.

Abstract: A method of manufacturing a heart valve prosthesis includes cutting a flat sheet of a valve material into a single-piece valve pattern having two or more valve leaflet regions and a valve skirt region. The method also includes arranging the two or more valve leaflet regions of the single-piece valve pattern into a mold for forming a leaflet belly for each of the two or more valve leaflet regions. Further, the method includes fixing, while arranged in the mold, a shape of the leaflet belly of each of two or more valve leaflet regions of the single piece-valve pattern. The method additionally includes creating a side seam by attaching two longitudinal edges of the single-piece valve pattern, to thereby form a tubular valve subassembly with two or more valve leaflets. The method includes attaching the tubular valve subassembly within a tubular frame to form a heart valve prosthesis.
