Abstract
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.
