Abstract: An intra vascular temperature management catheter incudes a shaft through which working fluid can circulate to and from a proximal location on the shaft. The catheter extends from a connector hub. At least one heat exchange member is supported by a distal part of the shaft or other part of the catheter to receive circulating working fluid from the proximal location. A temperature sensor is supported on the catheter for generating a temperature signal representative of blood temperature to a control system. The temperature sensor includes first and second conductive leads having respective first and second distal segments on or in the catheter shaft. The first and second distal segments are arranged to be in thermal contact with blood flowing past the catheter when the catheter is disposed in a blood vessel of a patient. Also, the temperature sensor includes a joining body connected to proximal segments of the first and second leads. The joining body may be supported in the hub or in another location proximal to the first and second conductive leads.

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 chest compression device includes a piston to apply compression to the sternum and incorporates leaf springs simultaneously driven by the piston to apply lateral compression to the thorax during chest compressions. A motor in the chest compression device provides motive power to cyclically extend and contract the piston to provide therapeutic chest compressions. One end of each leaf spring is operably connected to the piston and the other end of each leaf spring is secured to the backboard/base or to a support leg of the chest compression device such that during extension of the piston, each leaf spring is compressed against the device base or leg which causes the springs to flex and provide lateral compression of the patient's thorax in addition to the sternal compression of the piston.

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.
