In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.

Expandable endograft devices, systems, and methods of using the same to partially or fully occlude a luminal organ. An endograft device described herein may include a stent portion and a wall portion, wherein the wall portion is configured to receive a substance therein.

The invention relates to a tubular sleeve for the atraumatic treatment of hollow organs, wherein the sleeve is folded in an initial state and can be unfolded in order to lie against an inner wall of a hollow organ in a final state. The sleeve is characterized in that the sleeve is formed of an outer wall and an inner wall, which are arranged concentrically to each other, wherein the outer wall and the inner wall are tightly connected to each other at ends thereof in such a way that an approximately tubular compartment is formed in the region between the outer wall and the inner wall and the folding of the sleeve is directed about a sleeve longitudinal axis.

Medical appliances may be formed of multilayered constructs. The layers of the constructs may be configured with various physical properties or characteristics. The disposition and arrangement of each layer may be configured to create an overall construct with a combination of the individual properties of the layers. Constructs may be used to create vascular prostheses or other medical devices.

An embodiment includes a process for treating an abdominal aortic aneurysm (AAA) endoleak with a shape memory polymer (SMP) foam device. First, a bifurcated stent graft is placed within the aneurysm while a micro guidewire is positioned within the aneurysm for future catheter access. Second, after placing the iliac graft extension, a catheter is introduced over wire to deliver embolic foams. Third, embolic foams expand and conform to the aneurysm wall. Fourth, embolic foams create a stable thrombus to prevent endoleak formation by isolating peripheral vessels from the aneurysm volume.
