A stent comprises a tubular flexible body composed of a web structure that is expandable from a contracted delivery configuration to a deployed configuration and that comprises neighboring web patterns of alternating concavities extending circumferentially and adjoined by X-shaped transition sections. The web pattern may comprise either arcuate struts interconnected by bends, or a plurality of substantially straight sections with the transition sections formed by the junctions between pairs of adjacent bends of opposite curvatures.
