Analysis of Revascularisation in Ischemic Stroke With EmboTrap

Inclusion Criteria: * The patient or the patient's legally authorized representative has signed and dated an Informed Consent Form. * Aged between 18 years and 80 years (inclusive). * A new focal disabling neurologic deficit consistent with acute cerebral ischemia. * NIHSS score ≥8 and ≤25. * Pre-ictal mRS score of 0 or 1. * Angiographic confirmation of an occlusion of an ICA (including T and L occlusions), M1 or M2, MCA, or BA with TICI flow of 0-1. * Confirmation by the interventionalist, after screening CT or MRI, that the treatment site can be accessed with the Neuravi device. * The interventionalist estimates that at least one deployment of the Neuravi device can be completed within 5 hours from the onset of symptoms, or if time of onset of symptoms is unknown or \> 5 hours, patients can be included using imaging with the following criteria: 1. MRI criterion: ASPECTS 8 to 10, or,volume of diffusion restriction ≤30 mL and mismatch between perfusion reduction and diffusion restriction present. 2. CT criterion: ASPECTS 8 to 10 on baseline CT or CTA-source images, or, volume of significantly lowered CBV ≤30 mL and mismatch between perfusion reduction and low CBV present. Exclusion Criteria: * Life expectancy of less than 6 months. * Females who are pregnant or lactating. * History of severe allergy to contrast medium. * Has suffered a stroke in the past three months. * The patient presents with an NIHSS score \<8 or \>25 or is physician assessed as being in a clinically relevant uninterrupted coma. * Use of warfarin anticoagulation with International Normalized Ratio (INR) \> 3.0. * Platelet count \< 50,000. * Glucose \< 50 mg/dL. * Heparin use in previous 24 hours with PTT or ACT \> 2X normal. * Any known hemorrhagic or coagulation deficiency. * Computed tomography (CT) or Magnetic Resonance Imaging (MRI) evidence of recent/ fresh hemorrhage on presentation. * For basilar artery occlusion, extended early ischemic changes as confirmed by pc-ASPECTS ≤ 7 on baseline CT or CTA-source images, or extensive DWI lesions in the midbrain or pons regions on pre-treatment MRI. * Baseline CT or MRI showing mass effect or intracranial tumor (except small meningioma). * Excessive arterial tortuosity that precludes the study device from reaching the target vessel. * A proximal stenosis or complete occlusion that cannot, as judged by the responsible interventionalist, be treated safely or which prevents access to the occluded vessel with the Neuravi device. * Evidence of active infection. * Known cancer with metastases * Current use of cocaine or other vasoactive substance.
