EXPANDABLE BIFURCATED STENT AND METHOD FOR DELIVERY OF SAME |
摘要 |
An expandable 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 having a longitudinal axis and a porous surface defined by a plurality intersecting members arranged to define a first repeating pattern which is a polygon having a pair of side walls substantially parallel to the longitudinal axis, a first concave-shaped wall and a second convex-shaped wall connecting the side walls, the first wall and the second wall being equidistant along an axis which is parallel to the longitudinal axis, the stent being expandable from a first, contracted position to a second, expanded position upon the application of a radially outward force on the interior of the stent. A particularly preferred form of the stent is an expandable bifurcated stent comprising a proximal end and a distal end in communication with one another, the proximal end comprising a primary passageway and the distal end comprising a pair of secondary passageways, 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. A method of delivering the bifurcated stent to a target body passageway is also provided.
