    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.

    Abstract: A catheter includes working fluid supply and return lumens through which working fluid circulates to exchange heat with a patient in whom the catheter is positioned. Plural wires arranged in a mesh are located longitudinally along the catheter and engaged therewith. The mesh can be moved between a radially expanded configuration, in which the mesh circumscribes an inner wall of a vessel in which the catheter is disposed and in which blood flowing through the vessel is not significantly impeded from flowing within the mesh past the catheter, and a radially collapsed configuration, in which the mesh lies against the catheter or is closely spaced therefrom to facilitate advancement and retraction of the catheter from the vessel.

    Abstract: A transatrial intravascular temperature management catheter has a lower heat exchange segment positionable in the inferior vena cava and an upper heat exchange segment positionable in the superior vane cava, with a connecting segment lying between the two and positionable in the right atrium. A temperature sensor on the distal tip of the upper heat exchange segment provides accurate core body temperature signals for feedback purposes since the blood flowing past the sensor has not yet reached the heat exchange segment.

    Abstract: A control system for an arterial catheter operable to selectively impede blood flow includes a processor and a storage medium accessible to the processor that bears instructions which when executed by the processor cause the processor to execute logic including receiving a first signal representing a physical parameter associated with a patient in whom the catheter is disposed, receiving a second signal representative of time, and causing inflation of a first balloon on the catheter to impede blood flow in the first artery. Based at least in part on the first signal satisfying a first condition, the instructions include causing deflation of the first balloon. Based at least in part on the second signal indicating elapse of a predetermined time period, the instructions include causing deflation of the first balloon regardless of whether the first signal satisfies the first condition.
