Abstract: Closed loop heat exchange catheters having bi-directional flow heat exchange regions and their methods of manufacture and use. The heat exchange region may be formed of expandable or non-expandable tubular conduit(s) that are configured in a series of loops or coiled configuration defining a supply flow path and a return flow path through which heat exchange medium is circulated. The individual loops of convolutions of the coiled configuration may be the same or different size. In some embodiments, the tubular conduit(s) may be passed through generally transverse bore holes formed in a catheter shaft so that the loops or convolutions of protrude from the catheter shaft.

Abstract: Methods and systems for delivering gas-enriched blood within a vasculature of a patient may include providing a gas-enrichment system, the gas-enrichment system comprising a mixing chamber and a blood pump. The process may include inserting a catheter for drawing blood from the patient into a radial artery of the patient. The process may include drawing blood from the radial artery or from a vessel upstream of the radial artery at a blood flow rate without collapsing the artery or vessel to a degree that would substantially impede drawing blood. The process may include generating a gas-enriched blood by mixing the withdrawn blood with a gas-enriched liquid in a mixing chamber. The process may include delivering the gas-enriched blood to the vasculature of the patient.

Abstract: In some implementations, data obtained by a temperature management system for delivering temperature management therapy to a patient is presented, within a single display region, as a graph of patient temperature over time representing the timespans of all phases of a multi-phase temperature management therapy. The graph may be fitted to present each phase separately in a manner that retains data complexity. The graph may include power data representing power output over time by a temperature management device. Data from other devices may be incorporated into the graph. A portion of the data may be patient temperature data and/or patient physiological data gathered during a time preceding temperature management therapy by the temperature management device.

Abstract: The present disclosure provides systems and methods for controlling gas enrichment therapy. One or more sensors is used to measure one or more physiological parameters, e.g., blood or tissue oxygen parameters, of the patient. A processor is used to generate based on the measured parameters an alert through a user interface indicating a value or level of the measured physiological parameter, which is indicative of an effectiveness of the gas enrichment therapy.

Abstract: A mechanical chest compression device is secured to a gurney, transport stretcher or ambulance cot while engaging a patient's thorax to provide mechanical CPR during transport. The mechanical chest compression device compresses the patient's thorax against the gurney deck. The mechanical chest compression device may engage the side rails on the gurney, the gurney deck or any suitable structural elements of the gurney.

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: 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.
