1. A method for retrograde venous perfusion, comprising the steps of:

  • providing a catheter having a proximal end, a distal end, a first lumen extending from the proximal end to an infusion port located at the distal end, an expandable occluder located proximal the infusion port, and a second lumen extending from the proximal end to a return port located proximal the expandable occluder;

    inserting the catheter into the vena cava;

    positioning the occluder in the superior vena cava;

    expanding the occluder;

    withdrawing venous blood from the vena cava through the return port and the second lumen; and

    infusing oxygenated medium into the superior vena cava through the first lumen and infusion port, wherein oxygenated medium is returned to the cerebral tissues by retrograde venous perfusion.
