Abstract:
1. A stent graft system for intraluminal deployment in an aorta and a branch vessel comprising: an aorta stent graft for deployment within the aorta and defining a lumen for the passage of blood therethrough, and having a fenestration positioned and sized so as to allow blood to flow to a contiguous branch vessel; a branch vessel prosthesis having a tubular portion and a flaring portion, such that, when deployed, the flaring portion is located within the lumen of the aorta stent graft and the tubular portion passes through the fenestration and into the branch vessel; a balloon expansion catheter having first and second balloons, wherein the first balloon is aligned substantially with the flaring portion and the second balloon is aligned substantially with the tubular portion such that inflation of the first balloon flares the flaring portion and inflation of the second balloon expands the tubular portion, and wherein the second balloon is less compliant than the first balloon.
