Abstract: Cold plates through which refrigerant flows define a slot between them that can receive a cassette through which sterile working fluid with a relatively low flow rate flows from an intravascular heat exchange catheter. The working fluid from the catheter is heated or cooled by heat exchange with the cold plates through the walls of the cassette to maintain the sterility of the working fluid. On the other hand, high flow rate working fluid chambers surround the cold plates and non-sterile working fluid from an external heat exchange pad flows through the high flow rate working fluid chambers to exchange heat through direct contact with the cold plates.

Abstract: Systems, methods and devices for utilizing heat transfer parameters or energy expenditure of devices providing controlled hypothermia, normothermia or hyperthermia to detect changes, or the absence of changes, a patient's endogenous set-point temperature; which is not available during exogenously induced targeted temperature management. A particular embodiment would allow detection of fever in patients undergoing targeted temperature managed.

Abstract: Endovascular heat exchange systems and methods wherein a heat exchange catheter is positionable within the vasculature of a patent to exchange heat with the patient's flowing blood. The rate at which heat is being exchanged is determined and quantitative blood flow determinations may be made based on the rate of heat exchange. The system provides notification(s) to personnel when one or more blood flow-related events occur(s), such as a) resumption or continuation of effective spontaneous circulation; b) cessation of absence of effective spontaneous circulation, c) the occurrence of spontaneous or cardiac-compression-generated circulation that is below a minimum effective blood flow rate and e) the occurrence of spontaneous or cardiac-compression-generated circulation that is at or above a minimum effective blood flow rate.

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.

Abstract: An intelligent rechargeable battery pack having a battery management system for monitoring and controlling the charging and discharging of the battery pack is described. The battery management system includes primary and secondary protection circuits for monitoring the charging and discharging of the battery. Individual battery cells forming the battery pack are connected by a main bus to a connector for connection to a battery charger or a device to be powered, and the main bus may be interrupted by a switch controlled by the battery management system to prevent damage to the battery during charging or discharging of the battery.

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 of any one of several disclosed variations is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within one of various described re-usable control units. The control units include a heater/cooler device, a user input device, and a processor connected to receive input from various sensors around the body and the system. The heater/cooler device may be thermoelectric to enable both heating and 15″ cooling based on polarity. A temperature control scheme for ramping the body temperature up or down without overshoot is provided. The disposable heat exchange cassettes may include an integral pump head that engages with a pump drive mechanism within the re-usable control unit. More than one control unit may be provided to receive the same heat exchange cassette so that, for example, a large capacity control unit can be used initially, and a smaller, battery-powered unit can be substituted once the patient reaches the desired target temperature.

Abstract: Devices and methods for warming or cooling blood flowing through the vasculature of a human or animal subject so as to alter or control the temperature of all or part of the subject's body. Heat exchangers are positioned within the subject's vasculature and heated or cooled heat exchange fluid is circulated through the heat exchanger. For certain therapeutic applications, the heat exchanger and associated elements of the system have sufficient power to lower the subject's body temperature by at least 3 degrees C. in less than 30 minutes.
