Abstract
An expandable stent having a proximal end and a distal end in communication with one another, and a tubular wall disposed between the proximal end and the distal end. The tubular wall has a longitudinal axis and a porous surface defined by a plurality of intersecting members comprising a series of longitudinal struts disposed substantially parallel to the longitudinal axis of the stent. Each longitudinal strut in the series comprises flexure members for substantially complementary extension and compression of a diametrically opposed pair of the longitudinal struts upon flexure of the stent. The flexure members may comprise first and second curved sections which are of a different size. At least one of the curved sections may comprise an arc of greater than about 180°.
