  • Heat exchange catheters with bi-directional fluid flow and their methods of manufacture and use
    Patent number: 9662243
    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.

  • Intra-aortic balloon counterpulsation with concurrent hypothermia
    Patent number: 9533086
    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.

    Publication number: 20160354235
    Abstract: Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. The control unit includes a heater/cooler device for providing heated or cooled fluid to a heat exchanger in thermal communication with the fluid heat exchange medium circulating to the heat exchange catheter, a user input device, and a processor connected to receive input from various sensors around the body and the system. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.

  • Heat exchange catheter and their methods of manufacture and use
    Patent number: 9492633
    Abstract: A closed loop catheter useable for heat exchange is manufactured by forming a plurality of generally transverse bore holes though a flexible, multilumen catheter body, lacing a tube trough the bore holes so that loops of the tube protrude from the catheter body, connecting one end of the tube to an inflow lumen of the catheter and connecting the other end of the tube to an outflow lumen of the catheter. A heated or cooled heat exchange medium may then be circulated through the tube while the catheter is inserted in the vasculature of a subject, thereby resulting in heat exchange between the subject's flowing blood and the heat exchange medium being circulated through the tube.

  • CHEST COMPRESSION DEVICE
    Publication number: 20160310359
    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.

  • Heat exchange system for patient temperature control with multiple coolant chambers for multiple heat exchange modalities
    Patent number: 9474644
    Abstract: Cold plates through which refrigerant flows define a slot between them that can receive a cassette through which sterile working fluid with a relatively low flow rate flows from an intravascular heat exchange catheter. The working fluid from the catheter is heated or cooled by heat exchange with the cold plates through the walls of the cassette to maintain the sterility of the working fluid. On the other hand, high flow rate working fluid chambers surround the cold plates and non-sterile working fluid from an external heat exchange pad flows through the high flow rate working fluid chambers to exchange heat through direct contact with the cold plates.
