Inclusion criteria: * Age greater than or equal to (\>=) 18 years, less than or equal to (\<=) 90 years, at the time of consent * Signs and symptoms consistent with the diagnosis of acute ischemic stroke in the anterior circulation that can be treated with endovascular thrombectomy approaches * Endovascular treatment can be initiated (defined as access puncture) within 24 hours from time last known well * Baseline National Institutes of Health Stroke Scale (NIHSS) score \>= 6 * A signed and dated Informed Consent Form (ICF) or Investigator Statement for emergency procedure (as allowed according to country regulations and approved by EC) has been obtained Exclusion criteria: * Known pregnancy, as evidenced by positive pregnancy test for women of childbearing potential or breast feeding * Life expectancy less than (\<) 90 days prior to stroke onset * Known hemorrhagic diathesis disorder, coagulation factor deficiency or oral anticoagulant therapy with known International Normalized Ratio (INR) greater than (\>) 3.0 * Clinical symptoms and/or CT/MRI evidence suggestive of bilateral stroke or stroke in multiple vascular territories, defined as occlusions in more than one vessel not downstream from each other (for example, bilateral anterior circulation, anterior/posterior circulation) * Clinical history, past imaging or clinical judgement suggest that the intracranial occlusion is chronic * Computed Tomography/ Magnetic Resonance Imaging (CT/MRI) evidence of recent/fresh hemorrhage * Baseline CT or MRI showing mass effect * Currently participating in an investigational (drug, device, etc.) clinical trial that may confound study endpoints. Patients in observational, natural history, and/or epidemiological studies not involving intervention are eligible * Cerebral catheter angiographic evidence of pre-existing arterial disease, that potentially impacts treatment and/or outcome (for example, vasculitis) * Any occlusion or stenosis that limits device access to the target area (for example, carotid dissection, tandem occlusions) or requiring acute stenting to achieve access * Cerebral catheter angiographic evidence of multiple cerebrovascular occlusions, defined as occlusions in more than one vessel not downstream from each other (for example, bilateral anterior circulation, anterior/posterior circulation) * Excessive vascular access tortuosity that will likely prevent endovascular access with the adaptive tip catheter (ATC) * Baseline expanded thrombolysis in cerebral infarction (eTICI) \> 1
