Abstract: A system for internal iliac preservation includes a catheter having a distal catheter portion and a proximal catheter portion; a first guidewire having a proximal portion extending from the proximal catheter portion, a distal portion and a medial portion disposed between the proximal portion and the distal portion; a first outer sheath slidably disposed over distal catheter portion; and an integrated second delivery system disposed within the outer sheath at the distal catheter portion. The integrated second delivery system includes a second guidewire; an expandable stent-graft disposed over a lumen of the second guidewire, and a slidable connector slidably disposed over the medial portion of the first guidewire, where the second guidewire is slidably engaged with the slidable connection to permit movement of the integrated second delivery system along the first guidewire when the first outer sheath is retracted from distal catheter portion.

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.

Abstract: The invention provides a stent-graft system comprising a graft member and a stent having a connection end interconnected with the graft member and a free end opposed thereto. A belt retaining structure is provided at the stent free end. A belt is releasably retained in the belt retaining structure and is configured to constrain the stent free end independent of the stent connection end. A method of securing at least one end of a stent-graft within a vessel is also provided.
