  • Patent number: 8545754
    Abstract: Disclosed is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit. The apparatus has an inlet and an outlet that is located radially outward from the inlet in order to define a flowpath through the apparatus. The apparatus comprises: a core that is substantially centrally located in the apparatus and to which blood from a patient can be supplied through the inlet; a heat exchanger comprising a plurality of heat transfer elements that are arranged around the core and between which blood from the core can move radially outward; and an oxygenator comprising a plurality of gas exchange elements that are arranged around the heat exchanger and between which blood from the heat exchanger can move radially outward before exiting the apparatus through the outlet.

  • Patent number: 7829018
    Abstract: A disposable, integrated extracorporeal blood circuit employed during cardiopulmonary bypass surgery performs gas exchange, heat transfer, and microemboli filtering functions in a way as to conserve volume, to reduce setup and change out times, to eliminate a venous blood reservoir, and to substantially reduce blood-air interface. Blood from the patient or prime solution is routed through an air removal device that is equipped with air sensors for detection of air. An active air removal controller removes detected air from blood in the air removal device. A disposable circuit support module is used to mount the components of the disposable, integrated extracorporeal blood circuit in close proximity and in a desirable spatial relationship to optimize priming and use of the disposable, integrated extracorporeal blood circuit. A reusable circuit holder supports the disposable circuit support module in relation to a prime solution source, the active air removal controller and other components.

  • Publication number: 20100272607
    Abstract: Described is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit, the apparatus having an inlet and an outlet that is located radially outward from the inlet in order to define a flowpath through the apparatus, the apparatus comprising: a core in communication with the inlet such that blood from a patient can be supplied to the core, the core comprising a first element and a second element that interfit to define openings, wherein the elements and the openings together enhance flow of blood from the patient radially outward from the core; a heat exchanger that is arranged about the core and through which blood from the core can move radially outward; and an oxygenator that is arranged about the heat exchanger and through which blood from the heat exchanger can move radially outward before exiting the apparatus through the outlet.

  • Publication number: 20100272606
    Abstract: Described is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit comprising: an inlet mandrel that is configured such that the blood moves radially outward from the inlet mandrel through the openings in a radial direction; a heat exchanger arranged around the inlet mandrel, wherein blood can move radially outward with the transfer of heat to or from the blood; an oxygenator arranged around the heat exchanger, wherein blood can move from the heat exchanger radially outward with the transfer of oxygen into the blood; and a housing that houses the inlet mandrel, the heat exchanger and the oxygenator, and that comprises a blood inlet in communication with the inlet mandrel in order to allow blood to enter the apparatus from the patient, and a blood outlet in communication with the oxygenator in order for blood to exit the apparatus, wherein the blood outlet is located in the housing radially outward from the inlet.
