Post-Procedural Follow-up:This will be conducted by a clinical research assistant who is blinded to the study intervention. The specifics of the follow-up procedure are detailed below: Day1: The NIHSS clinical scoring tool will be performed on the stoke inpatient unit. This scale is a validated tool to objectively quantify disability following a stroke. The tool entails assessment of level of consciousness, motor function, sensation, coordination, speech and concentration. Currently, this tool is utilised at LHSC as part of the follow-up for AIS post-procedural days 1. Day 1-2: All patients will have a CT angiogram and MRI within 24-48 hours post-procedure as per usual standard of care. From these scans, the Thrombolysis in Cerebral Infarction (TICI) scale and final infarct volume will be calculated. Day 7: The NIHSS will be repeated to quantify ongoing disability. Day 90: As per the usual standard of care, all patient discharged from hospital will have a 3 month post-stroke outpatient follow-up appointment. The mRS and NIHSS will be repeated by the clinical research assistant at the neurological outpatient appointment. Should the appointment be delayed longer than 3 months post-stroke, a telephone call will be made by the clinical research assistant to determine the mRS. If the patient remains an inpatient at 90 days post-stroke, the electronic record will be accessed to gain the required information to calculate the mRS
