Abstract
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.

An endovascular prosthesis and/or delivery system, comprising:
- a bifurcated prosthesis comprising:
- a main tubular body having an open end and opposed ipsilateral and contralateral legs defining a graft wall therein between, said ipsilateral and contralateral legs having open ends;
- and
- a web of biocompatible material disposed between the contralateral leg and the ipsilateral leg and secured to the contralateral leg and the ipsilateral leg:
- wherein the web is a sheet of biocompatible material;
- and
- wherein the contralateral leg is restricted from significant longitudinal movement so as to prevent bunching up of the contralateral leg during delivery of the endovascular prosthesis.
An endovascular delivery system, comprising:
- a bifurcated prosthesis comprising:
- a main tubular body having an open end and opposed ipsilateral and contralateral legs defining a graft wall therein between, said ipsilateral and contralateral legs having open ends;
- said contralateral leg comprising having a hole through the graft wall at a location near the open end of the contralateral leg;
- and
- a release wire slidable disposed within the hole of the contralateral leg and within the ipsilateral leg;
- wherein withdrawal of the release wire releases the contralateral leg from and the ipsilateral leg.
