We demonstrate a new concept for endovascular embolization of nonnecked fusiform aneurysms. A device prototype consisting of a stent augmented with expandable foam, both made from shape memory polymer, was fabricated and deployed in an in vitro model. Visual observation indicated that the foam achieved embolization of the aneurysm while the stent maintained an open lumen in the parent artery. The shape memory polymer stent-foam device is a potential tool for treatment of nonnecked fusiform aneurysms, as well as an alternative to stent- and balloon-assisted coil embolization of wide-necked aneurysms.
