The Neurovascular Balloon Catheter has a small profile to cross cerebral vascular lesions, allowing the balloon to easily navigate and pass through tortuous and complex vascular segments. To enhance safety during access, the balloon is treated by the manufacturer to minimize friction, thereby helping to prevent damage to the vessel wall and ensuring safe delivery of the balloon to the lesion site. Furthermore, the application of laser welding technology combined with a tapered tip design allows the balloon catheter to enter the lesion site smoothly.
