  • Working fluid cassette with hinged plenum or enclosure for interfacing heat exchanger with intravascular temperature management catheter
    Patent number: 10022265
    Abstract: An enclosure or plenum that supports a looped pump tube is hingedly connected to a framed thin-walled heat exchange bag through which working fluid from an intravascular heat exchange catheter flows. The frame with bag can be inserted between cold plates to exchange heat with the working fluid flowing through the bag. With the framed bag between the plates, the looped pump tube from the enclosure or plenum is receivable in the raceway of a peristaltic pump, which pumps working fluid through the system.

  • Heat exchange system for patient temperature control with easy loading high performance peristaltic pump
    Patent number: 9784263
    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.

  • APPARATUS AND METHOD FOR ESOPHAGEAL COOLING
    Publication number: 20170281403
    Abstract: A balloon catheter is used in a closed-loop heat exchange system for manipulating the temperature of a patient. The balloon catheter is positioned in the stomach of the patient, and then expanded with a heat exchange fluid delivered through a lumen formed in the shaft of the catheter. The balloon catheter comes into contact with the wall of the stomach, and the stomach substantially conforms around the expanded balloon catheter. The heat exchange fluid is allowed to flow continuously into and out of the balloon catheter. Heat is exchanged between the balloon catheter and the stomach so as to controllably alter the temperature of at least a portion of the patient. Anti-shivering mechanisms and automatic control based on temperature feedback from the patient may be used in connection with the heat exchange system.

  • Control system for arterial catheter
    Patent number: 9737693
    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.
