Abstract: An embodiment includes a system comprising: an outer conduit; a shape memory polymer (SMP) foam; a metal backbone including: (a)(i) a first portion that extends from the SMP foam proximal end to the SMP foam distal end and which is generally covered by the SMP foam, and (a)(ii) a distal portion that extends distally from the SMP foam distal end and which is not covered by the SMP foam; wherein: (b)(i) SMP foam and the metal backbone are both included within the outer conduit adjacent to the outer conduit distal end; (b)(ii) the metal backbone distal portion transitions from a secondary shape that is uncoiled to a primary shape that is coiled; and (b)(iii) the metal backbone distal portion is in the metal backbone distal portion secondary shape and is located between the SMP foam distal end and the distal end of the outer conduit.

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.
