Patent ID: 8715337

Claim:
An endoluminal prosthesis having an inflow end and an outflow end that is downstream of the inflow end, the prosthesis comprising: a first stent at the inflow end of the prosthesis, wherein the first stent is configured to lie at least partially within a native valve annulus; a tubular conduit comprising an aortic valve replacement, the aortic valve replacement positioned downstream of the first stent, wherein at least a portion of the tubular conduit overlaps at least a portion of the first stent; and a second stent downstream of the first stent that overlaps at least a portion of the tubular conduit, wherein ones of the first stent, tubular conduit, and the second stent are coaxially arranged for unidirectionally passing fluid through the prosthesis, and wherein the first and second stents lack an overlapping relationship with one another, wherein the first stent and the tubular conduit are configured to allow fluid to pass unidirectionally therethrough, wherein an outflow end of the tubular conduit terminates at a location between proximal and distal ends of the second stent, wherein the second stent comprises at least one uncovered region, distal to the aortic valve replacement, to allow fluid to pass radially outside of an outer perimeter of the second stent after passing through the aortic valve replacement, wherein the second stent comprises a proximal zone having a first diameter and a distal zone having a second diameter, where the first diameter is narrower than the second diameter, and there is a taper between the first and second diameters, and wherein the taper of the second stent is positioned at least partially downstream of the aortic valve replacement.
