Abstract

See full text

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 of interconnected struts, the interconnected struts comprising a gradient of strut thickness from a first end to a second end of the tubular wall, 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 stent is ideally suited for applications in which a tortuous pathway must be followed to the stenosis or blockage and in which high radial rigidity of the expanded stent is required e.g., the treatment of ostial stenosis.
