Abstract:
1. A stent graft comprising an elongate tubular body of a biocompatible graft material, the tubular body comprising a distal end and a proximal end, the tubular body comprising a proximal portion of a first selected diameter, a distal portion of a second selected diameter, the second selected diameter being less than the first selected diameter and a tapered central portion between the proximal portion and the distal portion, the tubular body comprising a circumference, a notional anterior longitudinal datum line on the tubular body and a notional transverse clock face having 12 o'clock at the notional anterior longitudinal datum line; a scalloped cut out in the proximal portion of the tubular body, the scalloped cut out being open at the proximal end of the tubular body; a fenestration in the proximal portion, the fenestration being distal of the scalloped cut out; a first fenestration assembly and a second fenestration assembly in the distal end of the tapered central portion, the scalloped cut out being circumferentially centered with respect to the notional transverse clock face at 12:30 o'clock, the fenestration in the proximal portion being circumferentially centered with respect to the notional transverse clock face at 12:00 o'clock, the first fenestration assembly being circumferentially centered with respect to the notional transverse clock face at 2:15 o'clock and the second fenestration assembly being circumferentially centered with respect to the notional transverse clock face at 10:00 o'clock.
