Abstract: A stent graft includes a pair of generally opposed windows alignable with the superior mesentery artery, the celiac trunk and separated by graft material. A stent is provided spanning the window and in contact with the adjacent graft material and the stent presses the adjacent graft material into engagement with the adjacent wall of the flow lumen. A branch graft connection into the renal arteries may also be provided.

Abstract: Methods and devices for improving biofixation of implantable vascular devices are provided. The methods and devices improve biofixation of implantable vascular devices by providing one or more thrombus-eliminating agents at a treatment site before and/or during and/or after vascular device implantation.

Abstract: Universal modular stented graft assemblies are assembled, on site, and often in a patient's parent artery, from at least two components; a first component and a second component. The first and second components each include a window, or fenestration. The second component couples with the first component by fitting at least partially in the first component to form the universal modular stent graft assembly with an adjustable collateral opening. As the first and second components are assembled, the first and second components are adjusted relative to each other so that the first and second component windows overlap to form a collateral opening whose size is selectable, depending on the overlap, with the desired position and dimensions in the universal modular stent graft assembly.

Abstract: A unitary or integral stent graft having both structural and fluid exclusion properties if formed. The stent graft includes structural elements, such as wires, which are interdigitated with fluid barrier elements, such as a fabric, to form a unitary body such that the graft need not be sewn or otherwise attached to a structural stent member. In one aspect, the stent graft has a shape memory feature, such that is may be manufactured in its final use configuration, distorted for easy delivery to an aneurysmal blood vessel, site and deployed, and in location regain its original shape.
