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 .
