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: 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: A chest compression device with a chest compression belt assembly including guards and sensors operable with a control system to control operation of the system depending on detection of proper installation of the guards.
Abstract: A system includes a battery pack having an archive, and a portable medical device configured to releasably receive the battery pack. The portable medical device includes a memory and a processor controlled by commands embedded in and/or executed upon the processor and configured to collect, in the memory, operational history data and/or performance data related to the functioning of the portable medical device during use, and load, from the memory to the archive of the battery pack, the operational history data and/or performance data. The battery pack is configured to enable transfer of the operational history data and/or performance data of the portable medical device to a network or server.
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 a memory for storing data related to the operation of the battery, and the battery management system is also configured to communicate the data related to the operation of the battery to other processors for analysis.
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: An intravascular temperature management catheter includes 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.

Abstract: A carrier, such as a battery, that queries a memory of a charger or charging circuit, or the memory of equipment or discharging circuit powered by the battery, to determine the relative date or version of data, operating parameters and/or software on both the battery and the equipment, and either provides updated data, operating parameters and/or software to the equipment, or retrieves later dated data, operating parameters and/or software from the equipment to update the memory of the battery and/or further distribute the updated data, operating parameter sand/or software to other batteries or equipment.
Abstract: A medical resuscitation system includes a platform for releasable coupling to a patient for delivery of mechanical chest compressions, the platform having sensor(s) for monitoring aspect(s) of compression delivery, and processing circuitry configured to control the delivery chest compressions during a patient therapy session; receive, during the session, signals from each sensor; and store, to a memory, operational data collected for use by an authorized user in troubleshooting a problem with the platform and/or gathering historic data regarding use of the platform, and clinical metrics regarding the delivery of the compressions during the session, where the clinical metrics are collected for use in a summary report accessible to a clinical user. The summary report may be transferred to a server or a portable computer readable medium. The operational data may be transferred to an accessory unit or data integrator configured to cooperate with the platform for providing the therapy.
