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: A tubular prosthetic device for implantation into a body lumen includes a first part including a tubular lumen and a second part including an attachment member. The second part is secured to the first part via various configurations, where the device is capable of being reduced to a diameter less than the diameter of traditional devices, for ease of use during implantation. Methods of using the device are also provided.

Abstract: A tandem modular endograft includes a main elongate tubular graft body having at least one circumferential inflatable channel disposed towards a proximal portion of the graft body wall and a plurality of circumferential inflatable channels disposed towards a distal portion of the graft body wall. A proximal expansion anchor is disposed at or secured to a proximal neck portion of the graft body wall. First and second elongate tubular stent-graft extensions may be percutaneously disposed into a distal end of the tubular graft body. In combination, proximal portions of the first and second stent-graft extensions are conformable to a shape of the open lumen of the main graft body.

Abstract: Some embodiments relate in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to stent grafts and methods of making and deploying same within the body of a patient. Stent embodiments may include tapered struts for an even distribution of strain. Stent embodiments may also include portions which are enlarged in a circumferential direction which may be configured to stabilize the stent in a constrained state.

Abstract: Thin PTFE layers are described having little or no node and fibril microstructure and methods of manufacturing PTFE layers are disclosed that allow for controllable permeability and porosity of the layers. In some embodiments, the PTFE layers may act as a barrier layer in an endovascular graft or other medical device.

Abstract: This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.

Abstract: An endovascular graft, which is configured to conform to the morphology of a vessel to be treated, includes a tubular ePTFE structure; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; and an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium. The inflatable ePTFE structure may be longitudinally disposed over the tubular ePTFE structure. The ePTFE structure may be a bifurcated structure having first and second bifurcated tubular structures, where the inflatable ePTFE structure is disposed over at least a portion of the first and second bifurcated tubular structures.
