Abstract:
A stent-graft for bridging an aneurysm in an aorta, the aneurysm being at least partially disposed between two renal arteries and two iliac arteries, comprising:a graft material defining two renal apertures each oriented to align with one of the two renal arteries when the stent-graft is in an expanded state; and a stent system for supporting the graft material in a contracted state wherein each renal aperture is contracted and the expanded state wherein each renal aperture is expanded; wherein the stent system, when in the expanded state, is adapted to press against a portion of the aortic wall above the first renal artery and against a portion of the aortic wall above the second renal artery; wherein the graft material defines a mesenteric aperture oriented to align with a superior mesenteric artery when the stent-graft is in an expanded state.
