Evaluation of the safety and performance of the BOBBY™ Balloon Guide Catheter (BGC) in patients with an acute ischemic stroke treatment, a sudden reduction or termination of the blood circulation of the brain, caused by a clot. Immediate treatment is needed to restore the blood circulation in the brain, performing a mechanical removal of the clot (thrombectomy). To prevent clot particles migrating in other parts of the brain circulation during the thrombectomy, balloon guiding catheters are inserted. The aim of the study is to evaluate the safety and performance of the balloon guide catheter BOBBY™ by collecting information from patients, treated with a mechanical thrombectomy and the balloon guide catheter (BOBBY™) after acute ischemic stroke
