Abstract: Apparatus and methods for treatment of stroke are provided. In a preferred embodiment, the present invention disposes at least one catheter having a distal occlusive member in either the common carotid artery (CCA) or both the vertebral artery (VA) and the CCA on the hemisphere of the cerebral occlusion. Blood flow in the opposing carotid and/or vertebral arteries may be inhibited. Retrograde or antegrade flow may be provided through either catheter independently to effectively control cerebral flow characteristics. Under such controlled flow conditions, a thrombectomy device may be used to treat the occlusion, and any emboli generated are directed into the catheter(s).

Abstract: Apparatus and methods for treating cerebral occlusions are provided, including a thrombectomy device having at least one deployable element. The deployable element is advanced through the occlusion in a contracted state, then self-deploys distal of the occlusion or, alternatively, may be deployed to a wide range of configurations using a physician-actuated deployment knob. The thrombectomy device then may be retracted to cause the deployable element to snare the occlusion, and/or rotated circumferentially to cause the fibrin strands of the occlusion to be wrapped around the deployable element.
