Bifurcated endovascular prosthesis having tethered contralateral leg

摘要

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.

1. 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 ipsilateral leg comprising an ipsilateral tab extending from the open end of said ipsilateral leg, said tab comprising at least two holes; an elongate guidewire having at least two outwardly projecting members, said outwardly projecting members being sized to at least partially fit within the at least one of said at least two holes of said ipsilateral tab; a release wire slidable disposed within the at least two outwardly projecting members of the elongate guidewire and within one of the at least two holes of said ipsilateral tab; and a tether having opposed contralateral and ipsilateral ends, said contralateral end of the tether being securably disposed at said open end of said contralateral leg, said ipsilateral end of the tether having a hole, said release wire being slidably disposed through the hole of the tether to so engage the tether; wherein withdrawal of the release wire releases the ipsilateral tab and the tether from the elongate guidewire.
