Abstract:
1. A stent graft configured for treatment of a thoracic ascending aortic dissection, the stent graft comprising: a proximal stent and a distal stent each including a plurality of broader apices defining a generally circular second stent end and comprising a tubular graft material body secured to and extending between the proximal and distal stents, forming a patent fluid passage between them; where each of the stents is secured to the graft material such that its broader apices extend beyond an end of the tubular graft material body; and where an outer diameter defined by the broader apices of the generally circular second stent end is greater than an outer diameter defined by the narrower apices of the generally circular first stent end; and at least one intermediate stent secured to the graft material between the proximal and distal stents, the at least one intermediate stent providing columnar support to maintain an open geometry of the tubular graft material body, where the first radius of curvature is from about 0.5 mm to about 1.5 mm, where the second radius of curvature is from about 4 mm to about 9 mm, and where a ratio of the first radius of curvature to the second radius of curvature is about 1:2.6to about 1:18, and where each of the proximal stent and the distal stent comprises at least one uncovered region.
