Patients presenting with symptoms of acute ischemic stroke who have evidence of a large vessel occlusion in the cerebral circulation will be assigned to either the Tianyi Revascularization Device or Solitaire FR Revascularization Device. Each treated patient will be followed and assessed for 3 months after randomization. Up to 238 evaluable patients at up to 18 centers presenting with acute ischemic stroke in vessels accessible to the Revascularization Device for revascularization within 8 hours of symptom onset. The hypothesis to be tested is that the safety and effectiveness of the Tianyi Revascularization Device for the revascularization of large vessel occlusion is not inferior to the Solitaire FR Revascularization Device.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1. aged 18-85 years\n2. within 8 hours after symptom onset\n3.
