Clinical experience with a shape memory polymer peripheral vascular embolisation plug: a case series

Abstract Background Shape memory polymers are materials that manufactured in a certain shape, can be stored temporary deformed and then return to – or remember their original shape upon exposure external stimuli such as temperature moisture. This property lends itself application endovascular medical devices. Peripheral vasculature embolisation devices incorporating this novel technology have become commercially available case series, where the data were collected part of post market registry, outlines initial clinical experience with these Results Eight cases described series. The disease state/conditions for which was indicated right common iliac artery aneurysms ( n = 3), type II endoleak into thoracic aorta following aneurysm repair 1), left inferior gluteal internal 2), splenomegaly, splenectomy planned after procedure 1). Target arteries 5–10 mm diameter. In each case, at least one IMPEDE Embolization Plug (IMP-Device) an appropriate diameter used. All procedures technically successful target vessel thrombosis achieved all cases. Follow-up imaging during 45–90-day collection timeframe showed sustained occlusion. series includes examples situations commonly encountered when embolising peripheral vasculature, namely, use multiple single combination other embolic (e.g., microcoils, gelatin sponge, PVA particles) same case. There no adverse events related specific device. Conclusions small illustrates safety efficacy sponge-based device medium sized further will demonstrate utility polymer
