Shortly after completing a thrombectomy procedure, a temporary carotid filter can be deployed downstream of an occlusion not treated by the thrombectomy (e.g. a carotid lesion having plaque buildup), and the temporary carotid filter can remain in place during the patient's recovery period following the ischemic stroke until a procedure to treat the remaining occlusion is completed and antiplatelet therapy is administered. The temporary carotid filter can anchor in place while deployed with or without being tethered to a wire extending through the patient's Femoral Artery.
