Abstract: A stent-graft delivery system includes a balloon (420), a sleeve (430) disposed over the balloon, and a stent graft (100) mounted over the sleeve. The sleeve includes a weakened area (436) between a first end and a second end of the sleeve such that when the balloon is expanded, the balloon expands from a center portion of the balloon towards the ends of the balloon. The weakened area of the sleeve may be a slit, a thinner wall section, grooves, notches, or other weakening features. The sleeve may be adhesively attached to an outer shaft of the catheter or to an outer surface of the balloon.
