Official title
a Prospective, Multi-center, Open-label, Non-inferiority, Randomized, Controlled Registration Trial of the Intracranial Stent for the Treatment of Intracranial Aneurysms: Rebridge
Overview
This trial was designed as a prospective, multicentre, open, non-inferiority, randomised controlled clinical trial, with the control devices being MicroVention's LVIS Intraluminal Support Device and LVIS Jr. Intraluminal Support Device. Approximately 200 subjects with intracranial aneurysms would be enrolled for stent-assisted coiling embolisation according to the inclusion and exclusion criteria specified in this trial protocol. Subjects were evaluated by mRS preoperatively, at the time of device implantation, at the time of discharge from the hospital, at 1 month (±7 days) postoperatively, at 6 months (±30 days) postoperatively, and at 12 months (±60 days) postoperatively; subjects would underwent DSA imaging at surgery and at 6 months (±30 days) postoperatively, and MRA or DSA imaging at 12 months (±60 days) postoperatively. Unplanned follow-up of the subjects would performed when necessary, and data would be recorded to evaluate the safety and efficacy of intracranial artery stent for stent-assisted coiling embolisation for the treatment of intracranial aneurysms.

Eligibility criteria
Inclusion criteria
- At the time of signing the informed consent form(ICF), the applicant shall be male or non-pregnant female, aged 18 to 80 years； Target aneurysms was diagnosed as intracranial widenecked saccular aneurysms by DSA/CTA/MRA； The target aneurysm should be suitable for stentassisted coiling surgery and could be treated through one operation； Subject or its legal representative should be able to understand the purpose of this study, also agree to comply with protocol and sign the informed consent form voluntarily.
Exclusion criteria
- Aneurysms unsuitable for stent-assisted coiling (i.e. aneurysm necks ≤ 4 mm and or body-to-neck ratio ≥ 2)； The distal diameter of the aneurysm-carrying artery is outside the range of application of the investigational device; mRS score ≥3; Subjects with recurrent aneurysms treated by stent-assisted coiling; Multiple aneurysms and all aneurysms requiring intervention; Subjects with ruptured aneurysms <30 days ; Significant stenosis (≥50%) or occlusion of parent artery; Subjects unsuitable for anaesthesia or endovascular surgical treatment, e.g. major diseases of the heart, lungs, liver, spleen and kidneys, brain tumours, severe active infections, disseminated intravascular coagulation, and a history of severe mental illness; Subjects undergoing major surgical procedures (e.g. tumour resection, surgery of vital organs, etc.) within 30 days prior to signing the informed consent form, or scheduled to undergo such procedures within 60 days after signing the informed consent form; Subjects with morphologies or pathologies that may interfere with device use, including, but not limited to: carotid artery coarctation, vasculitis, aortic coarctation, limited vascular access (e.g., severe intracranial vascular tortuosity, severe intracranial vasospasm unresponsive to medication, other anatomical or clinical pathologies that would prevent access to the device); Contraindications to stenting, including but not limited to: contraindication to DSA, allergy or intolerance to contrast media, allergy or intolerance to antiplatelet and anticoagulant medications required for treatment, allergy to nickel-titanium and platinum-tungsten and platinum-iridium alloys; Pregnant or breastfeeding women; Life expectancy less than 12 months; Subject participation in other drug or device studies that do not meet endpoints
