ABSTRACT:
A system for clipping an aneurysm which includes an aneurysm clip and an applicator that allows improved visual control during application. The aneurysm clip has a unitary, integral, cantilever spring and a unitary, integral, rigid ring. The cantilever spring has two arms, open in the unbiased position, provides a spring force, and defines the clipping force of the aneurysm clip. The cantilever spring also includes bulges positioned on the outer surface of the arms and a bend at the ends of the arms. The rigid ring slips over the arms, is retained by the bulges, and forces the arms together. The applicator includes a first leg including a pin adapted to engage the bend of the cantilever spring of the aneurysm clip and a second leg movable relative to the first leg which includes structure for engaging the rigid ring of the aneurysm clip. A scissoring or squeezing motion of the applicator handle moves the arms to slide the rigid ring on and off the arms of the cantilever spring of the aneurysm clip.
