A control system for deploying a stent graft (20) including a resilient ring stent (22) at one end, provides a delivery shaft (30) carrying the stent graft with the ring stent adjacent a proximal end (33) of the shaft for insertion into a lumen； a retractable sleeve (36) for containing the stent graft on the delivery shaft； a control handle (38) adjacent the distal end (34), of the delivery shaft； and stent peak (50, 52) and valley (70, 72) control wires extending from the proximal end of the delivery shaft to peak and valley controllers (58； 74, 76) at the control handle. Use of the control wires effects movement and/or rotation of the graft allowing fine control of deployment in the lumen.
