This is a prospective, multi-center, single arm feasibility study for the endovascular treatment of patients with acute ischemic anterior circulation strokes due to large vessel embolic occlusions using the transcarotid approach with flow reversal. Patients enrolled into the NITE 1 Study will have failed transfemoral therapy and will be followed immediately from post-op to 90 days.
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.
