Abstract: In an illustrative embodiment, a heat exchange catheter includes a catheter body and a heat exchange region. The catheter body includes a delivery lumen, a return lumen, an inner wall separating the delivery and return lumens, and a side wall defining at least one opening in communication with the delivery lumen. The inner wall defines an opening in communication with the delivery and return lumens. A first end of the heat exchange region is coupled to the delivery lumen of the catheter body through the at least one opening. The heat exchange region is configured to be in fluid communication with the delivery and return lumens of the catheter body to receive a working fluid. The opening of the inner wall is located such that the working fluid flowing through the delivery lumen of the catheter body is bifurcated between the heat exchange region and the return lumen.

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.

Abstract: A conformable garment or device, for example, for performing heat exchange with a patient, includes one or more tubes. At least one of the one or more tubes has a lumen configured to receive fluid for flowing through the lumen of that tube to heat or cool the tube. The one or more tubes may be coupled to form a conformable fabric or material, such that the conformable fabric or material conforms to a non-planar shape. The conformable garment or device may conform to cover a particular portion of the patient's body to heat or cool the patient's body.

Abstract: A temperature management system controls a temperature of a body of a patient and determines a value indicative of a thermoregulatory activity of the patient. The system includes a heat exchange system configured to exchange heat with a body of a patient and to record operational data while controlling the temperature of the body of the patient. The temperature management system receives temperature data from a sensor, controls the heat exchange system to maintain the temperature of the body of the patient within a target temperature range, receives, in response to the controlling, operational data, determines, based on the temperature data and the operational data, a value indicative of a thermoregulatory activity of the patient, and generates, based on the value, an alert through the user interface indicating the thermoregulatory activity of the patient.

Abstract: The present disclosure provides systems and methods for controlling gas-enrichment, e.g., oxygen-enrichment, therapy. One or more sensors and/or one or more imaging systems may be used to measure or determine one or more physiological parameters of the patient. Feedback regarding one or more physiological parameters or microvascular resistance may be provided for titrating or controlling the gas-enrichment therapy.

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: 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.

A CPR chest compression device with a battery retainer interoperable with the control system to provide for controlled shut-down when an operator attempts to remove the battery during operation.

Abstract: A working fluid cassette for an intravascular heat exchange catheter includes a frame holding two closely spaced, square polymeric membranes along the sides of which are disposed inlet and outlet tubes. Working fluid from the catheter is directed from the inlet tube between the membranes to the outlet tube. The cassette is closely received between two refrigerant cold plates to exchange heat with the working fluid, which is circulated back to the catheter.

Abstract: A heat exchange system for exchanging heat with working fluid from an intravascular heat exchange catheter or an external heat exchange pad includes a working fluid that circulates between the catheter or pad and a fluid cassette, and a refrigerant system that flows against the outer sides of cold plates between which the cassette is disposed.

Abstract: The present disclosure provides systems for controlling infusion of one or more supplements into blood received from a patient. The systems include at least one an extracorporeal circulatory support system including a pump, fluid conduits, and at least one a 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. 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.

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.
