Currently the development of the production of domestic medical devices is of special importance in the context of ensuring the healthcare system sustainability. Leveraging international experience in developing embolic coils, while considering the capabilities of Russian production, will enable the creation of devices that meet global standarts. The study aimed to conduct systematic evaluation of six endovascular coil models from leading foreign manufacturers and perform comprehensive assessment of the design features of the metal coil frames, including analysis of geometrical dimensions, materials used, and engineering solutions. Based on our findings and a comparison with clinical and experimental literature data we determined the optimal parameters for creating the coil prototype: the wire diameter 0.07–0.12 mm, coil-core type interlock mechanism, and atraumatic polymer tip. These solutions ensure the optimal combination of performance characteristics and manufacturability. The findings provide the basis for the development of domestic analogues meeting the today’s clinical requirements, considering the available production capacity.
