A Randomized, Concurrent Controlled Trial to Assess the Safety and Effectiveness of the Separator 3D as a Component of the Penumbra System in the Revascularization of Large Vessel Occlusion in Acute Ischemic Stroke

The Separator 3D is an additional Separator with a new tip configuration for the Penumbra System.

The Penumbra System® is a new generation of neuro-embolectomy devices specifically designed to remove thrombus through aspiration.The treatment paradigm of this System involves the introduction of the Reperfusion Catheter through a guide catheter into the intracranial vasculature, and guided over an appropriate guidewire to the site of primary occlusion. The Reperfusion Catheter is used in parallel with the Separator and an aspiration source (Aspiration Pump) to separate the thrombus and aspirate it from the occluded vessel.
