Abstract
Disclosed is a stent that is useful for treating a vascular bifurcation, the stent having a plurality of segments extending coaxially end to end along a longitudinal axis of the stent from a first end to a second end of the stent, each segment having a plurality of struts extending in a zig-zag pattern around the circumference of the stent, wherein the stent is expandable from reduced diameter to an expanded diameter, the second end of the stent having a larger diameter than the first end when expanded; and an eyelet integrally formed with the segment positioned adjacent the second end, and configured to receive a radiopaque marker therein. The stent provides an improvement over prior stents for treating a vascular bifurcation by allowing the stent to be deployed in the widened transitional zone of a bifurcation such that the second end of the stent is accurately positioned at the carina.
