A CONSTRAINT ARRANGEMENT FOR A STENT-GRAFT LOADED ONTO A DELIVERY SYSTEM

A constraint arrangement (1) for a stent-graft (10) loaded onto a delivery system (5) is disclosed. The constraint arrangement (1) comprises: a suture (100) extending circumferentially around an outside surface (22) of a graft from a first fixed end (103) fixed to a stent-graft (10) to a positionable region (60), and through the graft at a first constraining perforation (62) into the lumen (25) and returning out of the lumen (25) to the outside surface (22) of the graft at a second constraining perforation (64) to a second fixed end (108) fixed to the stent-graft (10), thereby forming a loop (120) of the suture (100) within a lumen (25) of the graft, the loop (120) wrapped circumferentially around a cannula (80) such that a pair of legs (122, 127) of the loop (120) hold the positionable region with respect to the cannula (80), wherein a bight (225) of the loop (120) extends through a gap between the legs (122, 127) and wherein the release wire (90) extends through the bight (225) thereby capturing the bight (225) and releaseably securing the loop (120) around the cannula (80).
