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 motor is coupled to the rotor to rotate the rotor plural are rollers arranged on the rotor to contact tubing disposed between the rotor and the raceway when the rotor is in the pump position. The motor is prevented from stopping at a predetermined angular position to facilitate loading and unloading tubing.

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 closed loop catheter useable for heat exchange is manufactured by forming a plurality of generally transverse bore holes though a flexible, multilumen catheter body, lacing a tube trough the bore holes so that loops of the tube protrude from the catheter body, connecting one end of the tube to an inflow lumen of the catheter and connecting the other end of the tube to an outflow lumen of the catheter. A heated or cooled heat exchange medium may then be circulated through the tube while the catheter is inserted in the vasculature of a subject, thereby resulting in heat exchange between the subject's flowing blood and the heat exchange medium being circulated through the tube.

Abstract: The present disclosure provides systems for controlling infusion of one or more supplements into blood received from a patient. The systems may include at least one extracorporeal circulatory support system including a pump, fluid conduits, and at least one sensor configured to measure one or more parameters of the blood. The system also may include a fluid flow regulator coupled to the extracorporeal circulatory support system; and a processor, a memory, and associated circuitry communicatively coupled to the at least one sensor and the at least one fluid flow regulator. The system receives measurement signals corresponding to parameters of blood from the at least one sensor and determines one or more target values for the parameters of blood based on a patient profile and/or the measurements. The system may control the fluid flow regulator to cause an infusion of at least one supplemental fluid from a supplemental fluid source into the blood.
