Two internal cooling devices are currently available for use: the Celsius Control System and the Cool Line System. These technologies are also referred to as endovascular heat-exchange catheters. Heat exchange occurs between cooled saline that passes through the heat-exchange portion of the catheter (in a coil with large surface area for heat exchange) and the blood that flows over the outer surface of the catheter.
