Abstract: A device for a tissue channel includes a device frame, a shape memory polymer foam segment coupled to the device frame, and an attachment structure coupled to the device frame. The device frame includes a proximal structure, a distal structure, and an intermediate structure coupled to the proximal structure and the distal structure. The proximal structure is configured to collapse to fit into a delivery structure and expand to block migration of the proximal structure. The distal structure is configured to collapse to fit into the delivery structure and expand to block migration of the distal structure. The intermediate structure is configured to fit in the tissue channel upon device deployment. The shape memory polymer foam segment is configured to compress to fit into the delivery structure and occlude the channel. The attachment structure is configured to attach and detach the device from a delivery guide.

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.
