1. A stent graft system, comprising:
a) a stent graft that includes
i) a luminal flexible graft component defining a proximal open end and a distal open end, and having an outside surface and an inside surface extending from the proximal open end to the distal open end, the inside surface defining a lumen having a longitudinal axis,
ii) a plurality of stents distributed longitudinally along the luminal flexible graft component, and
iii) a plurality of suture loops, each of which defined by a single loop of suture, and each of which is distributed both laterally and longitudinally relative to each other along the luminal flexible graft component when the luminal flexible graft component is not radially constricted in an arrangement that causes the stent graft to be in a radially constricted position when the plurality of suture loops are aligned only longitudinally along a longitudinal axis of the stent graft, wherein at least a portion of the plurality of suture loops are each nested between an opening of struts of a stent of the plurality of stents; and
b) at least one ligature having a proximal end and a distal end, the at least one ligature extending through the plurality of suture loops that are distributed laterally and longitudinally relative to each other along the longitudinal axis of the luminal flexible graft component, whereby tension on the at least one ligature or stiffness of the at least one ligature causes the plurality of suture loops along the longitudinal axis of the luminal flexible graft component to be only longitudinally aligned along the luminal flexible graft, thereby at least partially radially constricting the stent graft.
