Abstract: A one-piece vascular clip which includes a central helical spring section, first connecting sections joined by the spring section, second connecting sections extending from the first connecting sections to cross. First jaw sections extend from the second connecting sections. A return bend jaw section extends from each of the first jaw sections parallel and adjacent to the associated first jaw section. A horn extends outwardly from each of the return bend jaw sections.

Abstract: A holder for an aneurysm clip. A clip holding tool can be drawn into a tubular clip opening fitting. The clip holding tool has arms engageable with the aneurysm clip to hold the aneurysm clip. Portions of the arms are engageable with the interior of the clip opening fitting to cause the arms of the clip holding tool to close to clip holding position when the clip holding tool is drawn into the tubular clip opening fitting. A mouth defining surface of the clip opening fitting engages the aneurysm clip for causing opening of the aneurysm clip as the clip holding tool is advanced along the clip opening fitting.

Abstract: A machine for testing the force applied to jaws of an aneurysm clip. A pair of jaw support plates receive the jaws of the aneurysm clip on end portions thereof. One of the jaw support plates moves between a closed position and an open position in which the end portions of the jaw support plates are spaced so that the clip is open. A motor opens said one of the jaw support plates. Electric current supplied to the motor is measured to provide a measure of the force on the jaws of the clip.
