  • Patent number: 8491644
    Abstract: A portable patient cooling apparatus is provided that includes a self-contained refrigerator and on-board power storage supply for stand alone operation. The apparatus is interconnectable to one or more heat exchange devices (e.g. patient contact pads or intravascular catheters) through which a cooled fluid may be circulated for patient cooling. Such fluid may be liquid contained within a reservoir comprising the apparatus during periods of non-use. The apparatus preferably defines a total volume of less than about 0.04 m3, while having a total weight of less than about 15 kg to yield a total circulated fluid cooling capacity of at least 200 watts.

  • Publication number: 20080027368
    Abstract: A disposable cartridge for use in extracorporeal blood perfusions systems that have a control unit for controlling the flow of fluids. The cartridge has a housing defining a plurality of internal passageways that connect to a cardiopulmonary circuit, a cardioplegia circuit and a suction circuit. The cartridge may be fitted with one or more of a bubble trap, a filter, and a valve.

  • Publication number: 20050060012
    Abstract: A method and system is provided to induce mild hypothermia in a patient through controlled heating of the preoptic anterior hypothalamus (POAH) in conjunction with cooling of patient's body. The system employs an ultrasound transducer that may be positioned extracorporeally to a patient skull for emitting ultrasound energy to the POAH. The ultrasound energy heats the POAH to inhibit thermoregulatory responses of the body such that a cooling means may more effectively cool bodily tissue in order to reduce a patient's core body temperature. Feedback sensors may be positioned at various locations on the patient in order to monitor the patient's core body temperature. A control apparatus included with the system controls the amount of heat the POAH receives and the amount of cooling the body receives based on the feedback signals from the sensors.

  • Patent number: 6692518
    Abstract: A temperature control system provides for the optimal management of patient temperature during a surgical procedure, such as those which require the patient to on bypass. The system employs a plurality of controllers as well as a plurality of temperature control means in order to provide optimal temperature control. In one configuration of the invention, controllers for each of the heat exchange devices may be interconnected using a data link. The connection may provide for a master/slave relationship wherein temperature sensors included in each system are employable as temperature feedback for initiating temperature changes. This device may be configured such that it operates in conjunction with another device or provides stand alone temperature control.

  • Patent number: 6660027
    Abstract: An improved patient temperature exchange system and method is disclosed for use with one or more interconnectable patient contact pads. In one embodiment, the system includes a circulating pump for drawing fluid through the interconnected pad(s) under negative pressure, and for pumping the fluid through one of more heat exchange devices into a circulating reservoir. A make-up reservoir may be provided for gravity fluid flow into the circulating reservoir during the filling of the interconnectable pad(s) and for receiving fluid upon emptying of the interconnectable pad(s). During normal heating/cooling operations, the circulated fluid does not pass through the make-up reservoir, thereby yielding a highly responsive system. The make-up and circulatory reservoirs may be directly interconnected, with the make-up reservoir maintained at atmospheric pressure (e.g. via a non-spill vent).

  • Patent number: 5470531
    Abstract: An exchanger for oxygenating blood includes a casing having walls and a cavity, sheet material with first and second ends covering distal edges of the walls, and a cover extending over the cavity to sandwich the first and second ends of the sheet material between the cover and the edges of the walls. The cover is melted into the sheet material and the distal edges of the walls. In another embodiment, a blood oxygenator includes a first compartment having a closed casing divided by a folded sheet of membrane material forming a first blood chamber and a first gas chamber. The casing has first and second manifolds in fluid communication with the first blood chamber. A second compartment is interconnected with the first compartment and has a closed casing divided by a folded sheet of membrane material forming a second blood chamber and a second gas chamber. The casing has third and fourth spaced apart manifolds in fluid communication with the second blood chamber.

  • Patent number: 5468449
    Abstract: A method for manufacturing an exchanger includes the steps of folding sheet material in a series of pleats, placing the folded sheet material in a casing having an opening defined by walls with distal edges, covering the distal edges with end portions of the sheet material, and affixing a cover to the casing by simultaneously melting a portion of the cover and the sheet covered distal edges of the walls, and contacting the cover with the sheet material covering the distal edges of the walls. The method may also include melting a portion of the cover and/or the casing and placing the melted cover on the casing so that the melted portion contacts pleats of the sheet material, and permitting the melted material to cool and solidify and form a bond with the sheet material.
