1. A stent comprising:
- a plurality of narrower distal apices defining a first generally circular outer profile, at least one of said distal apices comprisingfirst and second generally straight portions anda first curved portion disposed between the first and second straight portions and comprising a first radius of curvature; and
a plurality of broader distal apices defining a second generally circular outer profile, at least one of said proximal apices comprisingthird and fourth generally straight portions anda second curved portion disposed between the third and fourth straight portions and comprising a second radius of curvature that is greater than the first radius of curvature,where an outer diameter defined by the broader apices of the second generally circular outer profile is greater than an outer diameter defined by the narrower apices of the first generally circular outer profile; and
where at least one of the first and second generally straight portions is continuous with at least one of the third and fourth generally straight portions.

Abstract
A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.

16. A stent comprising:
-
a plurality of broader apices forming a first generally circular outer profile and a plurality of narrower apices forming a second generally circular outer profile connected with the broader apices by a plurality of generally straight portions; where each broader apex comprises a first curved portion and each narrower 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 broader apices is greater than the radius of curvature of at least one of the narrower apices; and where an outer diameter defined by the first generally circular outer profile is greater than an outer diameter defined by the second generally circular outer profile.

17. The stent of claim Error! Reference source not found. where an outer circumference around the proximal apices is greater than an outer circumference around the distal apices.
- 18. The stent of claim Error! Reference source not found, further comprising a graft, where at least one distal apex of the stent is attached to the graft using one or more sutures.

23. A stent graft comprising:
-
a tube having first and second ends and comprising a graft material; at least one stent, including a plurality of narrow apices defining a first generally circular outer profile; and a plurality of broad apices defining a second generally circular outer profile; where adjacent broad and narrow apices alternate and are separated by generally straight intermediate portions; where at least some of the plurality of narrow apices are attached directly to the first end of the tube. - View Dependent Claims (24, 25)
