1. A method of isolating the cerebral circulation during a procedure, comprising the steps of:

  • advancing a catheter system through the right subclavian artery, through the aorta, and into the left common carotid artery, the catheter system comprising a control handle having a proximal filter control and a distal filter control, the proximal filter control comprising a sliding control, the distal filter control comprising a distal sheath deflection control and a distal filter sheath handle;

    opening a proximal filter within the brachiocephalic artery by withdrawing the sliding control; and

    positioning a distal sheath containing a distal filter by axially moving the distal filter control;

    deflecting the distal sheath by rotating a distal sheath deflection control relative to the distal filter sheath handle;

    opening the distal filter within the left common carotid artery by advancing a distal filter actuator.
