A temporary diameter reduction constraint arrangement for a stent graft in combination with a stent graft is disclosed. The stent graft has a proximal end and a distal end and comprises a biocompatible graft material tube and a plurality of longitudinally spaced apart self-expanding stents fastened thereto, including at least an end stent and a plurality of intermediate stents. The constraint arrangement comprises: an elongate receiver extending longitudinally within the graft material tube; a first wire extending longitudinally along the graft material tube in a first serpentine pattern; and a second wire extending longitudinally along the graft material tube in a second serpentine pattern, wherein at least one of the first and second wires repeatedly loops over the receiver along a longitudinal length of the stent graft thereby securing the stent graft to the receiver. In one embodiment there is also a plurality of loops of thread to reduce the stent graft.
