  • Modular extracorporeal ambulatory lung assist device
    Patent number: 12220515
    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.

  • MODULAR EXTRACORPOREAL AMBULATORY LUNG ASSIST DEVICE
    Publication number: 20210077706
    Abstract: A system for lung assist includes a plurality of fiber bundle sections which includes a fiber bundle housing defining a fiber bundle compartment with a fiber bundle positioned within. The fiber bundle includes a plurality of hollow gas permeable fibers. The fiber bundle housing further includes a gas inlet in fluid connection with the fiber bundle housing and in fluid connection with inlets of the plurality of hollow gas permeable fibers, a gas outlet in fluid connection with the housing and in fluid connection with outlets of the plurality of hollow gas permeable fibers, and a blood outlet in fluid connection with a first end of the fiber bundle. The system further includes a base section including a housing including a pressurizing compartment, a pressurizing mechanism within the pressurizing compartment, a blood inlet in fluid connection with the pressurizing compartment and a conduit.
