Abstract
The present disclosure relates to intravascular thrombectomy systems and methods for ablating a blockage and preventing the introduction of emboli into the blood stream during and after surgery performed to reduce or ablate the blockage in a blood vessel. The system includes a catheter sleeve having electrodes disposed proximate a distal end portion thereof, either at the distal end itself or axially spaced along the length of the catheter sleeve. The system further includes a capture element which is expandable to span the lumen of the vessel. The capture element is deployable downstream of the blockage. The electrodes of the catheter sleeve may be placed on one side of the blockage or on either side of the blockage.
