  • Publication number: 20220080095
    Abstract: A system for lung assist includes a plurality of fiber bundle sections. Each of the fiber bundle sections includes a fiber bundle housing defining a fiber bundle compartment therein and a fiber bundle positioned within the fiber bundle compartment. The fiber bundle includes a plurality of hollow gas permeable fibers configured to permit diffusion of gas between blood and an interior of the plurality of hollow gas permeable fibers. The plurality of hollow gas permeable fibers is positioned such that blood flows around the plurality of hollow gas permeable fibers when flowing through the fiber bundle compartment. Each fiber bundle is different in at least one property from each other fiber bundle.

  • Publication number: 20210283324
    Abstract: An extracorporeal system for lung assist includes a housing which includes a blood flow inlet in fluid connection with a pressurizing stator compartment, a fiber bundle compartment in fluid connection with the pressurizing stator compartment via a flow channel within the housing, and a blood flow outlet in fluid connection with the fiber bundle compartment. An impeller is rotatably positioned within the pressurizing compartment for pressurizing blood entering the pressurizing stator compartment from the blood flow inlet. The system further includes a fiber bundle positioned within the fiber bundle compartment. The fiber bundle includes a plurality of hollow gas permeable fibers. The plurality of hollow gas permeable fibers is adapted to permit diffusion of gas between blood and an interior of the hollow gas permeable fibers. The plurality of hollow gas permeable fibers is positioned such that blood flows around the plurality of hollow gas permeable fibers when flowing through the fiber bundle compartment.

  • Patent number: 10335530
    Abstract: An extracorporeal system for lung assist includes a system housing, which includes a blood flow inlet and a blood flow outlet and a fiber bundle housing movably positioned within the system housing. The fiber bundle housing includes a gas inlet and a gas outlet. A fiber bundle is in operative connection with the fiber bundle housing. The fiber bundle includes a plurality of hollow gas permeable fibers, wherein lumens of the plurality of hollow gas fibers are in fluid connection with the gas inlet at a first end thereof and in fluid connection with the gas outlet as a second end thereof. The system further includes an actuator to impart oscillatory motion to the fiber bundle housing and thereby to the fiber bundle.
