Inclusion criteria
Inclusion criteria: 1. Aged from 18 to 80 years, male or female; 2. Patients diagnosed as wide-neck intracranial aneurysms by brain CTA/MRA/DSA (neck width=4mm or bodyor a dome-to-neck ratio<2); 3.

Patients understand the purpose of the study, accept the follow-up period, and agree to comply with all requirements, agree to participate in the clinical trial and voluntarily sign the informed consent.
Exclusion criteria
Exclusion criteria: 1. Patients who have contraindications to antiplatelet and/or anticoagulant therapy or do not start antiplatelet therapy in time before treatment. 2. Patients with anatomical structure is not suitable for endovascular treatment due to severe vascular tortuosity or stenosis shown by angiography. 3. Known to be allergic to Nitinol platinum alloy and angiographic agents. 4. Conditions that in the opinion of the investigators would prevent patients from completing the study, such as the expected survival period of active tumor less than 1-year, high-risk group of cerebral thrombosis, heart failure and atrial fibrillation. 5. Patients combined moyamoya disease, intracranial tumor, intracranial arteriovenous malformation, intracranial arteriovenous fistula and intracranial hematoma. 6. The target aneurysm has previously received intravascular embolization or stent implantation treatment; 7. Multiple aneurysms or complex aneurysms; 8. Patients with acute ruptured aneurysm; 9.
