Abstract

This invention is a cooling catheter (100) a continuous internal path extending from a supply opening (116) to the distal end of the catheter, and then back to a return operning (118); thus forming a sealed path, and preventing any contact between the coolant, and the patient. The catheter may have various structural features such as a multi-lumen coolant path, a heat exchange bundle of multiple thin hollow fibers, various shapes, etc. One operating technique includes the physician inserting the catheter into the patient's body, attaching the supply opening to a coolant source, and applying suction to the return opening, causing coolant to travel within the predefined coolant path. In another embodiment, which may operate under pressure, and/or suction, the coolant comprises a slushy medium of ice particles in a liquid coolant.
