Abstract
An expandable stent having a proximal end and a distal end in communication with one another. A tubular wall is disposed between the proximal end and the distal end, and has a longitudinal axis. The tubular wall has a porous surface defined by a plurality of intersecting members arranged to define a first repeating pattern comprised of a polygon having a pair of sidewalls and substantially parallel to the longitudinal axis, a concave-shaped first wall having a first apex, and a convex-shaped second wall having a second apex. The first wall and the second wall connect the sidewalls, and at least one of the first apex and the second apex is substantially flat. The first apex and the second apex are of different lengths. The stent is expandable from a first, contracted position to a second, expanded position upon the application of a radially outward force on the stent.
