    摘要： A method for treating cardiac arrest includes defibrillating the patient and/or ventilating the patient and/or administering a cardiac arrest drug such as epinephrine to resuscitate the patient, and then cooling the patient's body temperature using one or more cooling catheters positioned in the central venous system of the patient and/or particularly cooling the patient's brain temperature using a catheter advanced into the aortic arch or into the carotid artery whereby a bolus of cold saline solution is introduced into the blood supplied to the brain to lower the brain temperature quickly, and further cooling or maintaining the brain temperature at a desired level by pumping coolant in a closed circuit formation between the catheter and the coolant source to remove heat from the blood supplied to the patient's brain.

    摘要： Catheters adapted to exchange heat with a body fluid flowing through a body conduit employ helical elongate lumens for heat transfer with the body fluid. The helical elongate lumen of a catheter forms multiple turns extending longitudinally of a portion of the catheter with the turns each being bonded to the catheter along a fraction of the length of the turn. The length of the lumen and its orientation in each turn has the lumen otherwise displaced over a major portion of its length from the elongate body. The turns of the helical lumen can be arranged in sets having different lengths to encounter all areas of the flow. One or more infusion lumens may also extend to an infusion port or ports. The helical elongate lumen is defined by an elongate, thin-walled element. This lumen is in fluid communication with a heater/chiller supplying a working fluid for heat transfer through the wall of the elongate element defining the helical elongate lumen. A proximal hub may be associated with the catheter to establish at least one suture anchor and to receive the heater/chiller flow through input and output lumens associated with the catheter and in fluid communication with the helical elongate lumens. The elongated lumens may also be arranged in non-helical arrangements such as in a semi-circular configuration, a figure-eight loop configuration or a random loop configuration.
