An endovascular prosthesis delivery system (100) comprises: an inner cannula (16) a prosthesis (2) releasably secured to the inner cannula (16), the prosthesis (2) having a radially-inwardly contracted delivery configuration and a radially-expanded deployed configuration, wherein the prosthesis comprises at least two suture loops (84, 86) secured to an outer surface of the prosthesis (2) and circumferentially spaced from each other a releasable trigger wire (78) extending along at least a portion of the length of the prosthesis, wherein the releasable trigger wire is wound around at least a portion of the inner cannula (16) and wherein the releasable trigger wire (78) engages at least one of the at least two suture loops (84, 86) to retain the prosthesis (2) in the radially-inwardly contracted delivery configuration.
