A device and system designed for use in a pre-hospital setting to cool the brain after injury is described. The device incorporates a cold insert into an arch that fits around the neck of a subject, without obstructing the airway of the subject. A cold insert, such as a frozen fluid or endothermic packet, is disposed within one or both of the terminal ends of the arch, adjacent to one or both of the subject's carotid arteries. The cooling effect is specifically directed to cool the blood flowing through the carotid artery to the brain. A system incorporating the device with a temperature monitor is also disclosed. The system allows a health care professional to monitor and regulate cooling as required in the pre-hospital setting.

A method as in claim 8, wherein proximal portions of the draw catheter and the return catheter have intermittent moveable rings. 14. A method as in claim 4, wherein establishing extracorporeal blood flow comprises externally connecting transcutaneous proximal portions of the draw catheter and return catheter to an external pump. 15. A method as in claim 4, wherein establishing extracorporeal blood flow comprises percutaneously accessing implanted ports which are connected to the draw catheter and the return catheter. 16. An improved method for recirculating blood to a patient, wherein the improvement comprises passing a draw catheter and a return catheter into a superior vena cava and placing the draw catheter beyond a distal end of the return catheter for establishing extracorporeal blood flow from the draw catheter to the return catheter, wherein a distal end of the draw catheter is disposed distally of the distal end of the return catheter by a distance in a range from 5 to 10 cm. 17. An improved method as in claim 16, wherein the distal end of the draw catheter is placed in a right atrium of a patient's heart. 18. An improved method as in claim 16, wherein the distal end of the return catheter is placed in a superior vena cava. 19. A kit comprising: a draw catheter; a return catheter; and instructions to use the draw catheter and the return catheter to recirculate blood to a patient according to any of claims 1-3 or 16-18. 20. A method for recirculating blood to a patient, said method comprising: placing a draw catheter so that a distal tip thereof is positioned in a right atrium of the patient's heart; and placing a return catheter so that a distal tip thereof is positioned in a superior vena cava; wherein extracorporeal blood flow from the draw catheter to the return catheter may be established; wherein the draw catheter and the return catheter both pass into the superior vena cava, with the draw catheter extending beyond a distal end of the return catheter; wherein the draw catheter and return catheter comprise elastomeric tubular bodies having substantially uniform diameters over their entire lengths, wherein a distal end of the draw catheter is chamfered. 21. A method for recirculating blood to a patient, said method comprising: placing a draw catheter so that a distal tip thereof is positioned in a right atrium of the patient's heart; and placing a return catheter so that a distal tip thereof is positioned in a superior vena cava; wherein extracorporeal blood flow from the draw catheter to the return catheter may be established; wherein the draw catheter and the return catheter both pass into the superior vena cava, with the draw catheter extending beyond a distal end of the return catheter; wherein the draw catheter and return catheter comprise elastomeric tubular bodies having substantially uniform diameters over their entire lengths, wherein the distal end of the return catheter is chamfered.
