The present invention relates to a device for the non-surgical clipping of aneurysms. The invention also includes methods of use to treat aneurysms, including intracranial aneurysms. The aneurysm is clipped by positioning a wire comprising a shape memory alloy, pre-set to a mutually twisted conformation, on opposite sides of the neck of the aneurysm and causing the wires to twist around each other. Thus, the aneurysm neck is substantially closed. The resulting thrombosis in the aneurysm further excludes the aneurysm from blood flow and pressure.

La présente invention concerne un dispositif permettant la découpe non chirurgicale d'anévrismes. L'invention concerne également des procédés d'utilisation pour traiter les anévrismes, y compris les anévrismes intracrâniens. L'anévrisme est découpé en plaçant un fil contenant un alliage à mémoire de forme, préréglé pour une conformation mutuellement spiralée, sur les côtés opposés du cou de l'anévrisme et amener les fils à se torsader. Ainsi, le cou de l'anévrisme est sensiblement fermé. La thrombose résultant de l'anévrisme soustrait l'anévrisme de l'écoulement et de la pression sanguin(e).
