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.
