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.

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.

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: Devices, systems and methods for treating disorders characterized by low cardiac output. The devices, systems and methods use intra-aortic balloon counterpulsation in combination with hypothermia of all or a portion of a human or veterinary patient's body to improve coronary perfusion and cardiac output. To effect the hypothermia, a heat exchange catheter may be positioned in the a patient's vasculature separately from the intra-aortic balloon counterpulsation catheter. Alternatively, a combination Intra-aortic balloon counterpulsation/heat exchange catheter may be utilized. Such combination catheter comprises a) a catheter sized for insertion into the aorta, b) a counterpulsation balloon and c) a heat exchanger. A drive/control system receives temperature and electrocardiograph signals and drives the inflation/deflation of the counterpulsation balloon as well as the heating/cooling of the heat exchanger.

Abstract: An externally-applied heat exchange pad has three layers laminated together, an inner and outer non-conductive layer and a middle conductive layer. A leak in the inner layer causes coolant to contact the middle layer and change impedance, which can be sensed and used as an indication of an impending total leak of the pad.

Abstract: A catheter has a hollow conduit through which working fluid from a heat exchange system flows. The conduit in turn is configured to extend along a longitudinal central axis in a continuously varying non-constant azimuthal orientation so that it defines a non-round enclosed passageway through which blood can flow to exchange heat through a wall of the conduit with the working fluid flowing within the conduit.

Abstract: An aortic occluder catheter with expandable balloons for increasing cerebral blood blow has one or more balloons on a catheter shaft. To assist the balloon in bearing up against arterial blood flow while positioned retrograde in the aorta, the balloon is bonded to the catheter shaft in tension.

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: An intravenous heat exchange catheter and/or an external cooling pad/bladder can be used to maintain hypothermia in, e.g., a cardiac arrest patient, but to accelerate the cooling process the patient first can be infused with cold saline before the opportunity arises to connect the catheter or pad to the patient.
