Abstract
An expandable intraluminal stent having a tubular shaped member having first and second ends defining an axial passageway therethrough. The tubular shaped member has a multiplicity of slots helically formed thereabout that are preferably provided in rows wherein the slots of each row are arranged in an end to end fashion. The tubular shaped member is initially disposable in a radially collapsed configuration such that the device may be passed into the lumen of a blood vessel, and subsequently expand to an operative configuration wherein it will frictionally engage the surrounding blood vessel wall to hold the device in fixed position within the blood vessel lumen. In an alternative embodiment, the stent is designed to accommodate a bifurcated vessel having a collateral vessel extending therefrom.
