我们提出了一个新的概念，血管内栓塞的非颈梭形动脉瘤。在体外模型中制造并展开了由可膨胀泡沫（均由形状记忆聚合物制成）增强的支架组成的器械原型。目视观察表明，泡沫实现了动脉瘤栓塞，而支架在载瘤动脉中保持管腔开放。形状记忆聚合物支架-泡沫器械是治疗非颈梭形动脉瘤的潜在工具，也是宽颈动脉瘤支架和球囊辅助弹簧圈栓塞的替代方法。
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.
