Feasibility Study of the Treatment of Acute Ischemic Stroke Using the NOVIS Transcarotid Neuroprotection System In Transcarotid Embolectomy
Study Objective is to establish the feasibility and safety of the NOVIS Transcarotid Neuroprotection System when used for the transcarotid intervention of patients that have a failed transfemoral endovascular therapy in the case of anterior circulation strokes due to large vessel embolic occlusions.
• 1\. Patients presenting with acute ischemic stroke of the anterior circulation with large vessel occlusions who are eligible for revascularization using endovascular therapies (stentrievers and/or aspiration devices)
• 2\. Occlusion of the intracranial ICA, MCA M1, proximal MCA M2, single-vessel MCA M2, dominant MCA M2, or co-dominant MCA M2 segments
• 3\. Patient has failed transfemoral therapy (see Appendix 4 for definition), and at least 15 minutes have elapsed from groin puncture
