1. A method of placing a side branch stent graft into a fenestration of a main stent graft having a first end, a second end, a main lumen, a side wall, and a fenestration in the side wall,
the side branch stent graft comprising a tubular body of biocompatible graft material having a first end and a second end, a lumen therethrough, an inside, an outside, a balloon radially expandable stent having a tubular portion inside the first end of the tubular body and having a selected diameter and a flareable extension portion extending longitudinally beyond the first end of the tubular body such that the extension portion of the balloon expandable stent is expandable radially beyond the selected diameter of the tubular body, a plurality of self radially expanding stents spaced apart on the tubular body and positioned on the outside of the tubular body towards the second end of the tubular body and a terminal self radially expanding stent on the inside of the tubular body at the second end of the tubular body,
the method comprising inserting the side branch graft through the fenestration of the main stent graft such that the extension portion of the side branch graft is disposed within the main lumen and the tubular body is disposed in a side branch vessel,
flaring the extension portion of the balloon expandable stent beyond the selected diameter of the tubular body,
expanding the balloon expandable stent within the lumen of the tubular body, and
expanding the self expanding stents.
