A stent graft delivery system, comprising: a) a handle; b) a guidewire catheter extending distally from the handle and having a distal end and a longitudinal axis; c) at least one tube having a proximal end and a distal end, the tube extending distally from the handle and arranged in parallel with the guidewire catheter; d) at least one wire extending through the at least one tube, wherein each wire is configured as a loop at the distal end of the tube, and having at least one proximal end at the handle; and e) a stent graft having i) a proximal open end and a distal open end, ii) a longitudinal axis, iii) a luminal graft component having an inside surface defining a graft lumen, iv) a plurality of stents (31,48) each extending about the luminal graft component and distributed about the longitudinal axis of the luminal graft component, wherein at least a portion of the stents include struts that are joined to define proximal apices and distal apices, and v) a plurality of suture loops nested between the struts of the stents, wherein the at least one wire extends through the suture loops to thereby secure the stent graft, wherein the stent graft extends about the guidewire catheter, and wherein the loop of the wire at least partially secures the stent graft, whereby retraction of the wire extending through the suture loops by pulling the wire at the proximal end of the at least one wire, so that the length of the said loop of the wire is reduced causes radial constriction of the respective suture loops and, consequently, radial constriction of the stents and the stent graft at the suture loops. a) a handle; b) a guidewire catheter extending distally from the handle and having a distal end and a longitudinal axis; c) at least one tube having a proximal end and a distal end, the tube extending distally from the handle and arranged in parallel with the guidewire catheter; d) at least one wire extending through the at least one tube, wherein each wire is configured as a loop at the distal end of the tube, and having at least one proximal end at the handle; and e) a stent graft having i) a proximal open end and a distal open end, ii) a longitudinal axis, iii) a luminal graft component having an inside surface defining a graft lumen, iv) a plurality of stents (31,48) each extending about the luminal graft component and distributed about the longitudinal axis of the luminal graft component, wherein at least a portion of the stents include struts that are joined to define proximal apices and distal apices, and v) a plurality of suture loops nested between the struts of the stents, wherein the at least one wire extends through the suture loops to thereby secure the stent graft, wherein the stent graft extends about the guidewire catheter, and wherein the loop of the wire at least partially secures the stent graft, whereby retraction of the wire extending through the suture loops by pulling the wire at the proximal end of the at least one wire, so that the length of the said loop of the wire is reduced causes radial constriction of the respective suture loops and, consequently, radial constriction of the stents and the stent graft at the suture loops. i) a proximal open end and a distal open end, ii) a longitudinal axis, iii) a luminal graft component having an inside surface defining a graft lumen, iv) a plurality of stents (31,48) each extending about the luminal graft component and distributed about the longitudinal axis of the luminal graft component, wherein at least a portion of the stents include struts that are joined to define proximal apices and distal apices, and v) a plurality of suture loops nested between the struts of the stents, wherein the at least one wire extends through the suture loops to thereby secure the stent graft,
