A system for deploying a stent-graft within a body vessel is provided. The system includes an expandable stent-graft having expandable stent rings attached thereto and a cannula extending through the stent-graft. The system includes a plurality of diameter reducing connectors extending around the circumference of the graft for reducing the diameter of the graft. The system further includes a plurality of trigger wires extending longitudinally along the perimeter of the graft. The trigger wires extend through the diameter reducing connectors to constrain the connectors for reducing the diameter of the stent-graft. The trigger wires are also releasably attached to the apices of a bare stent portion extending from the proximal end of the graft body. The trigger wires can be sequentially retracted to release the bare stent and the diameter reducing connectors to expand the stent-graft radially into engagement with the wall of the body vessel.
