1. A stent graft comprising a tube of graft material comprising:
a first end having an edge,
a second end having an edge,
a first tubular body portion directly adjacent the first end and having a first diameter,
a second tubular body portion directly adjacent the second end and having a second diameter,
a first tapered portion directly adjacent the first tubular body portion,
a second tapered portion directly adjacent the second tubular body portion,
an intermediate tubular body portion disposed between the first and second tapered portions having a sidewall and a diameter less than both of the first and second tubular body portions,
a series of zig zag stent rings extending from the first end to the second end, each of the series of zig zag stent rings comprising a series of adjacent struts and bends between the struts,
first and second fenestrations in the sidewall of the intermediate tubular body portion that are circumferentially offset from each other,
a third fenestration circumferentially between the first and second fenestrations and longitudinally spaced from the first and second fenestrations,
a first tubular extension extending from the first fenestration in the intermediate tubular body portion, a second tubular extension extending from the second fenestration in the intermediate tubular body portion, and a third tubular extension extending from the third fenestration in the intermediate tubular body portion, each of the first, second and third tubular extensions having a first end attached to the intermediate tubular body portion, a second free end defining an opening, a ring about the opening, a zig zag stent between the first and second ends,
a zig zag stent ring of the series of zig zag stent rings disposed on the first tubular body portion and adjacent to the first end, the circular zig zag stent comprising a series of adjacent struts and bends between the struts,
a cut out in the graft material at the first end and having a periphery, wherein at least a portion of the periphery of the cut out is defined by and attached to at least one strut of the series of adjacent struts of the zig zag stent ring disposed on the first tubular body portion.
