Age 22 to ≤ 80 years old\n2.

Participant meets one or more risk factors for IA rupture, such as age (≤70); hypertension; cigarette smoking; use of sympathomimetic drugs; Japanese or Finnish ancestry; history of prior aneurysmal subarachnoid hemorrhage (aSAH); familial intracranial aneurysms or SAH; clinical or radiological mass effect; reduced quality of life due to fear of rupture; IA size, location, and morphology (yielding 1 point or greater score per UIATS scale); documented growth of IA on serial imaging; presence of multiple IAs; and presence of concurrent pathology\n6.

Target aneurysm is unsuitable for flow diverter treatment\n2. Subject requires more than one flow diverter for target aneurysm treatment\n3. Has vessel characteristics, such as severe tortuosity, stenosis, atherosclerotic disease, or morphology that would preclude safe endovascular access to the target aneurysm necessary for treatment with the study device\n4. Received previous treatment of the target aneurysm or parent artery where it would interfere with the placement or proper apposition of the device\n5. Has a medical contraindication to study or procedure-related antiplatelet\u002Fanticoagulation medications (e.g., aspirin, clopidogrel\u002FPlavix, ticagrelor, Prasugrel, Gp IIb\u002FIIIa inhibitors, heparin, etc.), local or general anesthesia, or life-threatening allergy to contrast dye\n6. Has a known severe allergy to nickel, titanium or platinum\n7. Modified Rankin Score (mRS) assessment is ≥ 3 at screening or pre-procedure mRS could not be assessed\n8. The health of the participant or the validity of the study outcomes (e.g., high risk of neurologic events, worsening of clinical condition in the last 30 days) may be compromised by the participant's enrollment\n9. Subarachnoid hemorrhage occurred within 30 days prior to enrollment\n10. Intracranial parenchymal hemorrhage occurred within 60 days prior to enrollment\n11. Major surgery (including previous intracranial implant) occurred within previous 30 days or is planned in the next 120 days after treatment date\n12. Has more than one IA that requires treatment within 120 days of treatment date\n13. Received previous intracranial implant associated with the symptomatic or vascular distribution within the past 12 weeks prior to treatment date\n14. Requires adjunctive coiling during SVB procedure\n15. Chronic anticoagulation therapy is ongoing or known coagulopathy exists\n16. Has other known serious concurrent medical conditions such as active bacterial infection, heart disease (including atrial fibrillation, pacemaker, recent myocardial infarction \\[\\\u003C 12 weeks\\], symptomatic congestive heart failure, or carotid stenosis), kidney failure (e.g., \\>2.0mg\u002Fdl serum creatinine) or any other non-neurological disease-related acute life threatening illness to be treated in this trial, pulmonary disease, uncontrolled diabetes, progressive neurologic disorders, cancer requiring active treatment (e.g., chemotherapy, etc.) or on palliative care, vasculitis, high risk of ischemic stroke or recent stroke (within 30 days)\n17. Life expectancy is less than 5 years due to other illness or condition (in addition to an intracranial aneurysm)\n18. Unable to complete study follow-up due to dementia or psychiatric disorder, substance abuse, or history of noncompliance with medical advice\n19. Women who are pregnant or nursing at the time of enrollment or women who wish to become pregnant during the length of study participation\n20. Presence of intracranial mass (tumor, except meningioma that doesn't require surgery for 1 year) or non-treated arteriovenous malformation (AVM) in the territory of the target aneurysm\n21.

This device is used to treat unruptured intracranial aneurysms (a weak, bulging spot in a blood vessel in the brain that hasn't burst yet). The study aims to see how safe and effective the SVB Flow Diverter is for adults aged 22 to 80 who have certain types of unruptured aneurysms. Success in this study means that the aneurysm is completely closed off one year after the procedure, without significant narrowing of the main artery or needing another treatment. The current status of this study is unclear, and it plans to enroll 250 participants.","Participants will be followed for at least one year after the procedure to check for complete aneurysm closure.",110,"Not specified in the trial record.","Not stated in the trial record.",[30],"v2"]
