In recent years, endovascular coil embolization is becoming a standard treatment option for people with a cerebral aneurysm. Since the coil embolization needs advanced coil insertion technique, an analysis of the technique and development of a surgery system for assistance and training are desired. In this study, we have developed both a novel optical force sensor for coil delivery wire and a surgery system using this sensor. The system consists of the force sensor, a recorder of force signal, aneurysm image and surgeon's oice, and a force indicator using sound. We have evaluated the system and the first coil insertion force using simulated aneurysms of an arterial model and an in vivo. The results show that the insertion force relates to the deployment shape of the coil, the feedback through the force indicator using sound is very effective, and the recorder is useful for analysis of the coil embolization.
