Claim:
1. A stent-graft for treatment of a medical condition, the stent-graft comprising: a graft having proximal and distal ends, and further comprising a stent, the 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 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 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, and where a ratio of the first radius of curvature to the second radius of curvature is about 1:2.6 to about 1:18.
