Patent ID: 7909863

Claim:
A stent graft introducer in combination with a stent graft, the stent graft releasably retained on the stent graft introducer, the introducer comprising a trigger wire catheter and a plurality of trigger wires and each trigger wire extending in a loop of a trigger wire from the trigger wire catheter, the stent graft comprising a tubular body of a graft material and an exposed stent joined to and extending from one end of the tubular body, the exposed stent comprising a self expanding Z stent including a plurality of struts and proximal and distal bends therebetween, the distal bends being joined to a proximal end of the tubular body, a pair of struts and a proximal bend defining an apex which is a selected distance to the proximal bend away from the tubular body, wherein adjacent apices of the exposed stent comprise different strut lengths thereby defining different distances to the respective proximal bend from the tubular body, the stent graft being retained onto the introducer by the trigger wires, the loop of a trigger wire of the plurality of trigger wires passing through at least two adjacent apices of different distances to the bends from the tubular body whereby the at least two adjacent apices are retained in a stacked configuration by the trigger wire.
