Abstract
A one-piece aneurysm clip having an elongated flat ribbon body. The body includes a central helical portion joining first connecting portions, second connecting portions extending from the first connecting portions transversely of the first connecting portions and blade portions extending from the second connecting portions. Spring action of the helical portion urges the blade portions to substantially flatwise engaged position. A guide bar and stop member is mounted on one of the second connecting portions and has a guide bar position which overlies an opposed other of the second connecting portions to hold the blade portions in alignment. A stop portion of the guide bar and stop member is engageable by the other of the second connecting portions to limit opening of the clip.
