Abstract:Stent graft endoleak is a major problem in endovascular aneurysm repair (EVAR). Endoleak occurs after EVAR and may lead to aneurysm rupture, acute vessel thrombosis or occlusion. This study presents a novel design to potentially reduce endoleak with use of magnets. A ferromagnetic stent is deployed into the vessel lumen, and two external flexible magnetic rings are used to clamp on the proximal and distal necks of the stent. The rings impose epivascular magnetic pressure on the vessel wall to prevent the vesse… Show more
