Claim Text:
1. A stent-graft system for treatment of a medical condition, the stent-graft system comprising: a proximal component comprising a graft having proximal and distal ends, and further comprising a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where at least one of the distal apices of the proximal stent is attached to the graft using one or more sutures, where each proximal apex comprises a first curved portion and each distal apex comprises a second curved portion, where the first curved portion and the second curved portion each comprises at least one radius of curvature, and the radius of curvature of at least one of the proximal apices is greater than the radius of curvature of at least one of the distal apices; and a distal component comprising a graft having proximal and distal ends, where, upon deployment, the proximal and distal components at least partially overlap with one another to permit continuous fluid flow therebetween, where the distal component further comprises a proximal z-stent coupled to the graft, and where the proximal end of the graft comprises at least one scallop formed therein that generally follows the shape of the proximal z-stent, where a first radius of curvature of one of the distal apices is from about 0.5 mm to about 1.5 mm, where a second radius of curvature of one of the proximal apices is from about 4 mm to about 9 mm, where a ratio of the first radius of curvature to the second radius of curvature is about 1:2.6 to about 1:18, and where the proximal stent comprises at least one uncovered region.
