CA2192520A1 — Expandable stent and method for delivery of same

USPTO Abstract

An expandable stent comprising 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. The tubular wall having a longitudinal axis and a poroussurface defined by a plurality intersecting members arranged to define a first repeating pattern comprised of a polygon. The polygon has a pair of side walls 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 connecting the side walls. At least one of the first apex and the second apex is substantially flat. 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. A bifurcated stent including the first repeating pattern is also described.
