Patent ID: 7776079

Claim:
A bifurcated catheter assembly having an undeployed state and a deployed state, the assembly comprising: a bifurcated inflation shaft having a first inflation shaft and a second inflation shaft, the first inflation shaft defining a first inflation lumen and the second inflation shaft defining a second inflation lumen; a first balloon defining a first balloon lumen, the first balloon lumen in fluid communication with the first inflation lumen, the first balloon having a working portion that is substantially cylindrical in shape extending along a central axis of the first balloon; a second balloon defining a second balloon lumen, the second balloon lumen in fluid communication with the second inflation lumen, the second balloon defining a distal end of the second inflation shaft, the second balloon having a first end, a second end, and a length extending therebetween, the second balloon being conical shaped throughout its length, the second balloon disposed about a second balloon axis extending generally perpendicular to the central axis of the first balloon, the first end having a first diameter about the second balloon axis and being positioned radially most distal from the first balloon when the second balloon is expanded, and the second end having a second diameter about the second balloon axis and being positioned radially most proximal to the first balloon when the second balloon is inflated, the first diameter being smaller than the second diameter, the portion there between having a diameter about the second balloon axis that gradually decreases from the second diameter to the first diameter; and a stent having a primary stent body and longitudinal axis parallel to the central axis of the first balloon, wherein when the second balloon is deflated, the primary stent body is disposed about the first end of the second balloon, and the second end of the second balloon, and when the second balloon is inflated, the primary stent body is disposed about the second end of the second balloon and the first end of the second balloon extends through a side opening of the primary stent body.
