Abstract: A balloon catheter is used in a closed-loop heat exchange system for manipulating the temperature of a patient. The balloon catheter is positioned in the stomach of the patient, and then expanded with a heat exchange fluid delivered through a lumen formed in the shaft of the catheter. The balloon catheter comes into contact with the wall of the stomach, and the stomach substantially conforms around the expanded balloon catheter. The heat exchange fluid is allowed to flow continuously into and out of the balloon catheter. Heat is exchanged between the balloon catheter and the stomach so as to controllably alter the temperature of at least a portion of the patient. Anti-shivering mechanisms and automatic control based on temperature feedback from the patient may be used in connection with the heat exchange system.

Abstract: A catheter has a series of hollow loops arranged along a tube for carrying working fluid from a heat exchange system to exchange heat with a patient in whom the catheter is advanced. The loops when inflated are transverse to the catheter axis and parallel to each other, and circumscribe a hollow passageway through which blood can flow. Blood also flows around the outer perimeters of the loops.

Abstract: A catheter has an inner sleeve through which refrigerant circulates to and from a source of refrigerant. The catheter also has an outer sleeve surrounding the inner sleeve, including a distal end thereof. The outer sleeve is filled with a frozen biocompatible substance. The refrigerant is separated from the biocompatible substance by one or more walls of the inner sleeve such that the refrigerant is isolated from a patient in whom the catheter is positioned by both the inner sleeve and the frozen biocompatible substance. The refrigerant circulates through the catheter when the catheter is positioned in the patient to maintain the biocompatible substance frozen as heat is transferred from the patient to the biocompatible substance.

Abstract: Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. The control unit includes a heater/cooler device for providing heated or cooled fluid to a heat exchanger in thermal communication with the fluid heat exchange medium circulating to the heat exchange catheter, a user input device, and a processor connected to receive input from various sensors around the body and the system. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.

Abstract: A system and method for adding or removing heat from a heat exchange fluid circulating between an external heat exchanger and an intravascular heat exchange catheter is described. The system includes a two stage cooling system providing for a high rate of cooling in one stage and a lower rate of cooling in a second stage. Both stages may be used to provide maximal cooling while the second stage is used to provide improved control of the cooling rate as a target temperature is approached. The second stage may also be used to provide heat to the heat exchange fluid.

Abstract: A hybrid chest compression device includes a backboard with a motor and a drive spool housed within the backboard. There is also a piston support frame secured to the backboard forming a patient channel between the piston support frame and the backboard. There is a belt operably secured to the drive spool and enclosed within the backboard and the piston support frame and a piston operably housed within the piston support frame wherein motion of the belt actuates motion of the piston. Actuation of the motor results in cyclic rotation and counter-rotation of the motor and corresponding winding and unwinding of the belt on the drive spool to effectuate cyclic extension and retraction of the piston against the patient's chest to perform mechanical cardiopulmonary resuscitation.
