BIFURCATION STENT AND METHOD OF POSITIONING IN A BODY LUMEN
First Claim
1. A bifurcation stent, comprising:
- a plurality of segments extending coaxially end to end along a longitudinal axis of the bifurcation stent from a first end to a second end of the bifurcation stent, each segment having a plurality of struts extending in a zig-zag pattern extending around the circumference of the bifurcation stent, wherein the bifurcation stent is expandable from reduced diameter to an expanded diameter, the first end of the bifurcation stent having a larger diameter than the second end when expanded; and
an eyelet integrally formed with the segment positioned adjacent the first end, and configured to receive a radiopaque marker therein.

Abstract
A method of deploying a bifurcation stent at a vascular bifurcation of a main vessel into first and second branch vessels includes: positioning a bifurcation stent at a vascular bifurcation, the bifurcation stent expandable from a reduced diameter to an expanded diameter, the bifurcation stent comprising a first end, a second end, and a marker near the first end, wherein the first end diameter is larger than the second end diameter when the bifurcation stent is expanded, and wherein the bifurcation stent is positioned such that the marker is approximately aligned with a carinal plane at the vascular bifurcation; partially expanding the first end of the bifurcation stent; adjusting the position of the bifurcation stent such that the marker is positioned past the carinal plane and towards the first branch vessel; and deploying the bifurcation stent at the bifurcation. Devices are also disclosed.

13. A stent, having a tubular body with a first end and a second end, the stent expandable from a first, reduced diameter to a second, enlarged diameter, the stent further comprising at least a first radiopaque marker positioned beyond the first end of the stent, and at least a second and a third radiopaque markers positioned beyond the second end of the stent.
