Claim Text:
1. A device for positioning in a blood vessel adjacent to an aneurysm for causing thrombosis of the aneurysm while maintaining substantially normal flow through the blood vessel, said device comprising: a single elastic filament configurable between: (i) an elongated, substantially linear configuration, whereby to facilitate movement along a blood vessel; and (ii) a longitudinally-contracted, substantially three-dimensional configuration for lodging within the blood vessel, said longitudinally-contracted, substantially three-dimensional configuration providing (a) a face for positioning adjacent the aneurysm, said face comprising a plurality of lengths of said elastic filament in close proximity to one another so as to restrict blood flow to the aneurysm and thereby cause thrombosis of the aneurysm, and (b) a substantially open frame for holding said face adjacent the aneurysm, said substantially open frame configured so as to maintain substantially normal flow through the blood vessel; wherein said single elastic filament is formed from a sheet of shape memory material; wherein said single elastic filament is formed from the sheet of shape memory material so as to provide the single elastic filament with has a width which varies along its length a cross-section which varies along its length; wherein said single elastic filament comprises a continuous closed loop.
