Prospective Registry for Assessment of Acute Ischemic Stroke Patients Treated With Neurothrombectomy Devices in India

Prior treatment

• Concurrent participation in another mechanical neurothrombectomy device trial or any other clinical trial with an active treatment arm or where the study procedure or treatment might confound the study analysis

Other

• Significant mass effect with midline shift

• Subject/subject's legally authorized representative has given Informed Consent according to country regulations, and/or EC requirements
• Subject is 18 years of age or older
• Subject has experienced an Acute Ischemic Stroke due to large intracranial vessel occlusion in at least one of the following intracranial vessels: internal carotid artery (ICA), M1 and M2 segments of the middle cerebral artery (MCA), basilar, and vertebral arteries
