1. A system for supporting a body lumen, the system comprising:
- a tubular body having a web structure defining a wall, the web structure configured for expansion from a collapsed delivery configuration to an expanded deployed configuration, the web structure comprising a plurality of neighboring web patterns of alternating concavity that extend circumferentially around the wall, each web pattern including a plurality of arcuate webs interconnected by bends, neighboring web patterns interconnected by transition sections, wherein at least two of the transition sections are separated, around the circumference of the wall, by at least three arcuate webs; and
a catheter configured to accept the tubular body in the collapsed delivery configuration, the catheter configured to deliver the tubular body intravascularly and to transition the tubular body from the collapsed delivery configuration to the expanded deployed configuration.

Abstract
The present invention provides a stent comprising a tubular flexible body having a wall with a web structure that is expandable from a contracted delivery configuration to deployed configuration. The web structure comprises a plurality of neighboring web patterns, where each web patterns is composed of adjoining webs, and the web patterns are interconnected by transition sections. Each adjoining web comprises a central section interposed between two lateral sections to form concave or convex configurations. A delivery system for the stent is also provided.
