Abstract:
1. A device for treating a blood vessel aneurysm, said aneurysm being connected to said vessel by a neck, consisting essentially of: two shape memory alloy wires, each of said wires having been thermo-mechanically pre-set to a memorized twisted configuration, and a guiding needle configured to receive at least one of said wires, said guiding needle having a sharp tip for perforating a blood vessel wall; wherein said two wires have a generally straight, non-twisted deployment configuration and revert to said memorized twisted configuration when heated, wherein when deployed on opposite sides of said neck of said aneurysm and heated said two wires adopt a mutually twisted configuration, thereby pressing said neck of said aneurysm substantially closed to reduce pressure and blood flow into said aneurysm.
