<p>An unexpanded stent comprising a proximal end and a distal end in communication with one another, 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 intersecting members comprising rows of a repeating pattern (A,B) interconnected by longitudinal struts, the stent being expandable from a first, contracted position to a second, expanded position upon the application of a radially outward force on the stent, The longitudinal struts comprise an arcuate flexure means disposed in spaced relation between adjacent rows of the repeating pattern (A,B) to allow for substantially complementary extension and compression of a diametrically opposed pair of the longitudinal struts upon flexure of the stent. <IMAGE></p> |
