Abstract:
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.

Claim (Index 14):
A system comprising:\n a conduit that includes an open-cell, polyurethane, thermoset, shape memory polymer (SMP) foam; wherein the SMP foam is between 0 and 3 mm in diameter; wherein the SMP foam includes first and second cells which directly contact each other; wherein (a)(i) the first and second cells share and directly contact a ring of struts that provide structural support for the first and second cells, (a)(ii) a membrane directly contacts the ring of struts, and (a)(iii) the membrane is partially reticulated but not fully reticulated; wherein the partially reticulated membrane includes: (b)(i) a void that forms a path configured to allow fluid to flow between the first and second cells, (b)(ii) an interface, between the partially reticulated membrane and the void, which is rough and uneven; wherein the foam includes cells, including the first and second cells, which are anisotropic in shape and have unequal major and minor axes; wherein: (a) the ring of struts defines an outer perimeter of the membrane and the void defines an inner perimeter of the membrane; (b) an outer membrane area for the membrane is an area bounded by the outer perimeter defining an area of the membrane before reticulation; (c) a void area is an area bounded by the inner perimeter defining an area of the void; and (d) the void area is between 25% and 75% of the outer membrane area.
