A fitting device (104) for fitting a stent-graft (100) into a lumen of a patient includes a catheter (110), a cannula (112) reciprocably carried in the catheter (110) and a pair of gripper claws (106) in the cannula (112). The gripper claws (106) grip onto a stent (102) at the proximal end (128) of the stent-graft (100) which a suture loop (108) is tied to a stent (102) at an intermediate position along the stent graft (100). The stent-graft (100) can be curved by pulling the end-most stent (102) backwards, that is by retracting the cannula (112) into the catheter (110) while the gripper claws (106) grip onto the stent (102). The proximal end of the stent-graft (100) can also be adjusted position-wise by moving the cannula (112) into and out of the catheter (110). Thus, precise positioning and curving of the stent-graft (100) can be achieved.
