1. An endoluminal support assembly comprising:
- a first generally cylindrical stent having a length, first and second ends, an exterior and an interior, and a medial region, said first generally cylindrical stent defining a passageway therethrough;
a second generally cylindrical stent having a length shorter than the length of the first stent and disposed radially outwardly and the second stent entirely overlapping a first end of the first stent.

Abstract
An endovascular support assembly, or stent assembly, and a covered endovascular support assembly, or stent-graft assembly, with caps on either or both ends for improved and uniform deployment of the assembly. Additionally, the caps serve to capture the graft material between the caps and the endovascular support device or stent.

5. An endoluminal support assembly for implantation into a lumen, comprising:
-
a generally cylindrical endovascular support device having a length, first and second ends, an exterior and an interior, and a medial region, said generally cylindrical endovascular support device defining a passageway therethrough and having a compressed configuration for delivery to a site in the lumen and an expanded configuration; means for applying a force to the endovascular support device to form said expanded configuration; and means disposed entirely circumferentially about and along the exterior of one end of the endovascular support device for increasing the amount of force needed to expand said one end of the endovascular support device from the force needed to expand the medial region.
