Abstract: A thromboembolic removal system for treating ischemic stroke, including a guide and occlusion catheter, an aspiration catheter, an aspiration pump, and a thromboembolic separator. During aspiration of thromboembolic material through the aspiration catheter, the separator element is advanced from and retracted into the catheter lumen to break up or prevent clogs or flow restrictions formed by the thromboembolic material. Longitudinal channels in the separator allow aspiration through the aspiration catheter to continue even when the separator is disposed in the aspiration catheter lumen.
