An improved cerebral aneurysm clip fabricated from titanium or titanium alloys and utilizing a guide member consisting of a straight wire-like bridging guide secured across a U-shaped bend formed in one or both of the two cross arms of the aneurysm clip. The aneurysm clip is fabricated from a single, elongated resilient member of titanium or titanium alloy coiled at an intermediate portion to form a coil spring for normally urging the clamping arms of the clip together in a resilient manner. The clip further consists of two forearm sections extending outwardly and away from the coil spring in the direction of the clamping arms of the clip with the forearm sections terminating in inwardly bent first elbow portions that support respective cross arm sections. The cross arm sections extend from the respective first elbow portions in mutually crossing and slidably engaging relationship with each other and terminate in second inwardly bent elbow portions that support the respective clamping arms of the aneurysm clip. Because the clip is fabricated from titanium or titanium alloys, it can be readily color coded by a simple and safe electrolytic oxidation technique capable of providing a passivating oxide layer of different color for coding purposes for different sizes and shapes of clips being manufactured.
