Aneurysm clip is widely used as the primary treatment of complex brain aneurysm, primarily in a haemorrhage stroke due to cerebral blood vessel blockages or ruptures, leading to severe neurological deficits. In some developing countries, such as Indonesia, open surgical clipping is sometimes unaffordable and causes a financial burden to the state. This study aims to reproduce the commercial aneurysm clip using metal forming to be more independent in providing medical equipment throughout the country. The metal forming employed rolling and bending techniques, utilizing a base and a jig system to press the Ti6Al4V wire into the desired shape of an R-shaped contour. Our investigation confirmed their structural integrity, fine-grain structure, and mechanical properties. The density of the aneurysm clip shows 4.3 g/cm3 after the forming process. The chemical composition of the aneurysm clip tested with a scanning electron microscope equipped with an energy-dispersive X-ray spectrometer revealed the presence of Ti, Al, and V elements. The fabricated clip exhibited a closing force of 1.689 N. It is about double the closing force exerted by the commercial aneurysm clip, 0.791 N.
