An endovascular delivery system includes a bifurcated and inflatable prosthesis including a main tubular body having an open end and opposed ipsilateral and contralateral legs defining a graft wall therein between. A tether is disposed securably disposed to the contralateral leg, and the contralateral leg is releasably restrained towards the ipsilateral leg tether to prevent undesirable movement of the contralateral leg. A release wire within the endovascular delivery system releasably retains the tether near the ipsilateral leg. The contralateral leg (128) may also be restricted from significant longitudinal movement so as to prevent bunching up of the contralateral leg during delivery of the endovascular prosthesis by a web (210) of biocompatible material disposed between the contralateral leg (128) and the ipsilateral leg (126) and secured to the contralateral leg and the ipsilateral leg.
