A sterile, flexible tube designed for retrograde cerebral perfusion with oxygenated cold blood. It is a two-lumen tube with several side holes and a balloon attached at its tip. The device is inserted into the internal jugular vein via a puncture in such a way that the holes remain in the vein so they can be used for cerebral perfusion even in the case of competent venous valves at the jugular-subclavian junction. It is then advanced until the inflation of the balloon at its tip occludes the drainage veins (superior vena cava and azygos vein). It is used for brain protection during profound hypothermic circulatory arrest during aortic surgery. This is a single-use device.
