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.

Embodiments include, for example, mechanical release systems for implantable medical devices.

An implantable frame comprises a plurality of corner structures configured to decrease pressure to the vessel wall and define pulsatility enhancing windows of the implantable frame. The corner structures may comprise plurality of neighboring longitudinal struts that extend in a longitudinal direction of the blood vessel when placed to form the vessel wall to a substantially polygonal cross-section and distribute pressure loading of the corner structure among the plurality of neighboring longitudinal struts to improve biocompatibility. The corner structures also allow increased forming of the vessel wall and can provide stretching of the vessel wall to enhance pulsatility of the vessel wall.
