Abstract
A transatrial intravascular temperature management catheter has a lower heat exchange segment positionable in the inferior vena cava and an upper heat exchange segment positionable in the superior vane cava, with a connecting segment lying between the two and positionable in the right atrium. A temperature sensor on the distal tip of the upper heat exchange segment provides accurate core body temperature signals for feedback purposes since the blood flowing past the sensor has not yet reached the heat exchange segment.
