Abstract: A portable system for managing the temperature of a patient during transport includes a heater/cooler configured to be in fluid communication with a heat transfer catheter or a heat transfer surface pad; a pump for circulating heat exchange fluid; an alternating current power supply; and a processor configured to indicate if the alternating current power supply connection to the source of alternating current is interrupted. A rechargeable battery may be configured to provide power to the system when the alternating power supply is not connected to a source of alternating current. If the system is powered on and the connection to the alternating current source is interrupted, the system may automatically switch to receiving power from the rechargeable battery. The processor may alert an operator of the interruption of the connection to the alternating current source and indicate to the operator the amount of energy remaining in the battery.

Abstract: An enclosure or plenum that supports a looped pump tube is hingedly connected to a framed thin-walled heat exchange bag through which working fluid from an intravascular heat exchange catheter flows. The frame with bag can be inserted between cold plates to exchange heat with the working fluid flowing through the bag. With the framed bag between the plates, the looped pump tube from the enclosure or plenum is receivable in the raceway of a peristaltic pump, which pumps working fluid through the system.

Abstract: Methods and systems for bidirectional priming of a blood circuit while a catheter is connected to the circuit that delivers gas-enriched blood to a patient. The system primes the circuit while the catheter is connected to the circuit by controlling a first flow control mechanism to close to prevent blood flow through the draw line to a catheter and causes a pump to circulate blood in a first direction through a mixing chamber and/or through a bubble trap that removes air bubbles from the circuit. The system controls a second flow control mechanism to close to prevent blood flow in a return line to the catheter while causing the first flow control mechanism to open after the second flow control mechanism is closed and while causing the pump to circulate the blood in a second, opposite direction through the mixing chamber that removes air bubbles from the circuit.

Abstract: A temperature management system for ease and timing of priming, setup and/or operation by a user. The temperature management system is configured to control a temperature of a patient's body using a heat exchange device. The temperature management system includes a console that is coupled to a heat exchange device, such as a catheter or surface pad. The console includes a hardware interface for receiving or coupling to a fluid loop configured to supply the heat exchange device with heating or cooling working fluid (e.g., saline). The interface provides instructions, indicators, and/or hardware elements to assist a user in configuring and priming the fluid loop for operation.

Abstract: A peristaltic pump has an arcuate raceway with a partially concave inner surface extending through an arc of at least one hundred eighty degrees (180°). The arc defines a midpoint, and a rotor faces the inner surface of the raceway and is both rotatable relative to the raceway and translationally movable relative to the raceway between a pump position, wherein the rotor is spaced from the midpoint a first distance, and a tube load position, wherein the rotor is spaced from the midpoint a second distance greater than the first distance. A rotor motor is coupled to the rotor to rotate the rotor and rollers arranged on the rotor to contact tubing disposed between the rotor and the raceway when the rotor is in the pump position. A loading motor moves the rotor toward and away from the raceway.

Abstract: Devices, systems and methods for controlling a patient's body temperature by endovascular heat exchange.

Abstract: A working fluid cassette for an intravascular heat exchange catheter includes a frame holding two closely spaced, square polymeric membranes in tension. Working fluid from the catheter is directed between the membranes. The cassette is closely received between two refrigerant cold plates to exchange heat with the working fluid, which is circulated back to the catheter.
