Abstract: A device and method for treating pathological narrowing of fluid-carrying conduits of the human body (such as blood vessels) in an area of a bifurcation is disclosed. In particular, a stent system carries a self expandable noncylindrical stent, which is particularly suited for treating a widened portion of a blood vessel immediately proximal to a bifurcation. A stent delivery system is also disclosed, for delivering the stent such that a larger expanded diameter end of the stent faces the bifurcation, and a smaller expanded diameter end of the stent faces proximally in the main vessel.

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.

Abstract: A device and method for treating pathological narrowing of fluid-carrying conduits of the human body (such as blood vessels) in an area of a bifurcation is disclosed. In particular, a stent delivery system configured to carry one or more of a pair of dissimilar stents. At least one of the stents is particularly suited for treating a widened portion of a blood vessel immediately proximal to a bifurcation. The stent delivery system can also include a handpiece adapted to selectively deliver the stents.
