Interventional neurology devices are mainly used for stroke treatment. This paper outlines the application of coil grafts，intracranial aneurysm stents，intracranial covered stents，and flow diverters for the treatment of intracranial aneurysms；carotid artery stents，distal protection devices，and cerebral artery stents for the treatment of arterial stenosis；and thrombectomy devices for the treatment of acute ischemic stroke （AIS）. By sorting through the epidemiology and related prevailing products，we believe that imported alternative products and thrombectomy devices will usher in faster development.
