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: Heart valve prosthesis are disclosed that include a frame or support structure having an inflow portion, a valve-retaining tubular or central portion and a pair of support arms. The inflow portion radially extends from a first end of the valve-retaining tubular portion and the pair of support arms are circumferentially spaced apart and radially extend from an opposing second end of the valve-retaining tubular portion.
