[0002] An intracranial aneurysm is an abnormal bulge on the wall of an intracranial artery and is the first cause of subarachnoid hemorrhage. In cerebrovascular accidents, it ranks third only next to cerebral thrombosis and hypertensive cerebral hemorrhage. It can occur at any age, and most often occurs in middle-aged and elderly women aged 40 to 60. At present, most scholars believe that an intracranial aneurysm is caused on the basis of local congenital defects in the wall of an intracranial artery and increased intraluminal pressure. Hypertension, cerebral arteriosclerosis, and vasculitis are related to the occurrence and development of an aneurysm.

[0003] Generally, for patients with an intracranial aneurysm, craniotomy, aneurysm clipping, or intracranial aneurysm interventional embolization surgery can be used for treatment. With the continuous progress and maturity of technology, at present, most intracranial aneurysms are treated by interventional embolization, which can achieve good treatment effect. Through the interventional surgery, the head end of the guide tube is placed in the extracranial segment of the vertebral artery, the microcatheter is sent into the microcatheter under the guidance of the micro guide wire, the tip is sent into the intracranial aneurysm, the micro guide wire is sent into the aneurysm along the microcatheter, and the stent is carefully and accurately sent into the determined position, and then the stent is released to cover the aneurysm neck, and the spring coil is embolized into the aneurysm, so that the inside of the aneurysm becomes a dead space, the aneurysm wall gradually becomes ischemic and necrotic, thereby effectively eliminating the existence of the aneurysm.

[0004] The microcatheter, guide wire and other instruments used in interventional therapy are small in size and delicate in manufacture, and need to be sterile and carefully stored for timely use. In addition, the microcatheter and the guide wire are usually matched and used, and it is inconvenient to store and use them separately.
