Aneurysms, characterized by weakened areas in arterial walls, pose a significant risk of life-threatening hemorrhage and permanent brain damage upon rupture. In this research, we present a novel neurovascular embolization coil assembly comprising an embolization coil and a delivery system, aimed at addressing the challenges associated with embolism trauma. The neurovascular embolization coil system features a delivery configuration that enables precise deployment of the embolization coil. Additionally, it incorporates a secondary coil system consisting of predefined shapes and patterns, which are derived by customizing a primary coil made of a super-elastic shape memory material. The proposed delivery system offers notable advantages, including cost-effectiveness and safety. It facilitates easy detachment of the coil implant through a threading mechanism, reducing procedural complications and enhancing patient safety. To validate the performance of the developed delivery system, an invitro implantation study was conducted using a simulated neurovascular model under normal conditions. The study successfully demonstrated the efficient deployment of the embolization coil using the developed delivery system.
