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, each stent including struts that are joined at opposite ends to define distal and proximal apices, and wherein the stents are fixed circumferentially about the luminal flexible graft component; and iii) a plurality of suture loops spaced radially and longitudinally along the luminal flexible graft component in an arrangement that causes the stent graft to be in a radially constricted position when the suture loops are substantially aligned along a longitudinal axis of the stent graft, wherein the suture loops are nested between adjoining struts of a respective stent; and b) at least one ligature having a proximal end and a distal end, the ligature extending through a portion of the suture loops predominately distributed at a distinct longitudinal section of the stent graft flexible wall, whereby independent selective tension or withdrawal of the ligature will independently control radial expansion of the stents from the radially constricted position to an expanded position at each respective longitudinal section of the stent graft. 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, each stent including struts that are joined at opposite ends to define distal and proximal apices, and wherein the stents are fixed circumferentially about the luminal flexible graft component; and iii) a plurality of suture loops spaced radially and longitudinally along the luminal flexible graft component in an arrangement that causes the stent graft to be in a radially constricted position when the suture loops are substantially aligned along a longitudinal axis of the stent graft, wherein the suture loops are nested between adjoining struts of a respective stent; and 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, each stent including struts that are joined at opposite ends to define distal and proximal apices, and wherein the stents are fixed circumferentially about the luminal flexible graft component; and iii) a plurality of suture loops spaced radially and longitudinally along the luminal flexible graft component in an arrangement that causes the stent graft to be in a radially constricted position when the suture loops are substantially aligned along a longitudinal axis of the stent graft, wherein the suture loops are nested between adjoining struts of a respective stent; and b) at least one ligature having a proximal end and a distal end, the ligature extending through a portion of the suture loops predominately distributed at a distinct longitudinal section of the stent graft flexible wall, whereby independent selective tension or withdrawal of the ligature will independently control radial expansion of the stents from the radially constricted position to an expanded position at each respective longitudinal section of the stent graft.
