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 1):
A system comprising:\n a conduit that simultaneously includes: (a) a first open-cell, polyurethane, thermoset, shape memory polymer (SMP) foam; (b) a second open-cell, polyurethane, thermoset, SMP foam; and (c) a third open-cell, polyurethane, thermoset, SMP foam; wherein (a) the first SMP foam includes first and second ends that oppose each other, (b) the second SMP foam includes first and second ends that oppose each other, and (c) the third SMP foam includes first and second ends that oppose each other; wherein (a) the first SMP foam includes a first backbone that extends from the first end of the first SMP foam to the second end of the first SMP foam; (b) the second SMP foam includes a second backbone that extends from the first end of the second SMP foam to the second end of the second SMP foam; (a) the third SMP foam includes a third backbone that extends from the first end of the third SMP foam to the second end of the third SMP foam; wherein (a) the first, second, and third SMP foams are not fixedly coupled to each other; (b) the first, second, and third SMP foams are configured to deploy from the conduit such that they are not fixedly secured to one another immediately after their collective deployment from the conduit, and (c) the first, second, and third SMP foams are configured to deploy from the conduit in serial fashion such that the first SMP foam deploys from the conduit before the second SMP foam and the second SMP foam deploys form the conduit before the third SMP foam; wherein (a) the first backbone includes at least one of platinum, tantalum, iridium, tungsten, or polyurethane, (b) the second backbone includes at least one of platinum, tantalum, iridium, tungsten, or polyurethane, (c) the third backbone includes at least one of platinum, tantalum, iridium, tungsten, or polyurethane wherein (a) the first SMP foam is between 0 and 3 mm in diameter, (b) the second SMP foam is between 0 and 3 mm in diameter, and (c) the third SMP foam is between 0 and 3 mm in diameter.
