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.

Abstract: Systems and methods for managing aneurysms provide additional support to an aneurysmal wall by disposing a flexible vascular liner against or in close proximity to the aneurysmal wall. The liner is flexibly expansive to conform to the wall of the aneurysm. The liner inhibits failure of the aneurysmal wall. The liner may also inhibit further growth in diameter of the aneurysm. Aneurysms in single arteries or near branched arteries may be supported by a flexible vascular liner.

Abstract: Systems and methods for treating diseased bodily lumens involving branched lumen deployment sites include a main graft or stent-graft deployable in a main artery and a vent device or stent-graft deployable in a branch artery to maintain blood flow through the main artery and from the main artery to the branch artery. Systems and methods for treating diseased bodily lumens involving branched lumen deployment sites may also include a main graft or stent-graft deployable in the main artery, a chimney graft or stent-graft deployable in both branch artery and the main artery to the branch artery and a gutter-sealing device associated with the chimney graft to prevent flow of blood among the chimney graft, the main graft and a wall of the main artery.

Abstract: The vascular graft is located within a lumen of a vessel. The vascular graft includes a tubular structure and an attachment ring connected thereto. A stent attachment structure is connected to the attachment ring. The stent attachment structure is connected to an inner surface of the vessel to secure the location of the vascular graft within the lumen. The vascular graft is made according to a method in which the end of the tubular structure is folded over the attachment ring. Alternatively, the vascular graft has circumferential slits near the end thereof. Strap structures extend through the slits and are folded for connection to the stent attachment structure. The vascular graft is made according to a method in which the strap structures are inserted through the slits and folded for connection to the stent attachment structure.
