BIFURCATION STENT AND METHOD OF POSITIONING IN A BODY LUMEN

摘要

A method of deploying a bifurcation stent at a vascular bifurcation of a main vessel into first and second branch vessels includes: positioning a bif urcation stent at a vascular bifurcation, the bifurcation stent expandable f rom a reduced diameter to an expanded diameter, the bifurcation stent compri sing 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 bifurcat ion stent is expanded, and wherein the bifurcation stent is positioned such that the marker is approximately aligned with a carinal plane at the vascula r bifurcation; partially expanding the first end of the bifurcation stent; a djusting the position of the bifurcation stent such that the marker is posit ioned past the carinal plane and towards the first branch vessel; and deploy ing the bifurcation stent at the bifurcation. Devices are also disclosed.
