Abstract
A stent with a plurality of support elements that are deployable within a body for supporting a vessel or other body structure. The stent includes first and second terminal ends and a length extending between the terminal ends. Support rails extend between the terminal ends and through the support members in a direction parallel to the longitudinal axis of the stent. The support elements can include openings for receiving the rails. The rails can be formed of a spring so that the stent can easily conform to the minor bend of a curved vessel when the stent is deployed.

29. A stent for deploying within a body, said stent comprising:
-
first and second terminal ends and a length extending between said terminal ends;
at least one support rail extending between said terminal ends; and
a plurality of circumferentially extending support elements, said support elements each having an aperture that extends along a portion of the length of said stent, said at least one support rail being received within respective apertures so that said support elements are moveable relative to said rail between said terminal ends of said stent.
