A cerebral aneurysm is the dilation, bulging, or ballooning out of part of the wall of a vein or artery in the brain. If the cerebral aneurysm ruptures, it will become serious life-threatening condition. An aneurysm clip (sugita clip) is a medical instrumentation that is used in operation of the cerebral aneurysm to clip the ruptured aneurysm and to reduce the risk of rebleeding. In order to prevent the sugita clips from slipping out of the blood vessels, a number of pyramidal depressions are formed on their clamp surfaces. However, it was not verified whether the form of pyramidal depression was optimum or not. In this research, we used a THG laser process machine to produce the clamp surface with circular depressions or grooves. Frictional characteristics of each clamp surface was examined.
