  • Oxygenator with improved blood mixing
    Patent number: 12752044
    Abstract: An oxygenator may include a housing extending from a first end to a second end along a central longitudinal axis, a first end cap, a second end cap, and a bundle of hollow gas exchange fibers extending between the first end and the second end. The first end cap and the second end cap may each be rotatable about the central longitudinal axis. An oxygenator may include a bundle of hollow gas exchange fibers extending from the first end cap to the second end cap. An oxygenator may include a housing including a first axially expandable portion, a second axially expandable portion, and a rigid tubular portion disposed between and fixedly attached to the first and second axially expandable portions. An oxygenator may include a bundle of hollow gas exchange fibers may be axially movable relative to the housing.

  • OXYGENATOR WITH CIRCUMFERENTIALLY CONSTRICTING HOUSING
    Publication number: 20240399039
    Abstract: An oxygenator may include a housing extending from a first end to a second end, and a bundle of hollow gas exchange fibers extending between the first end and the second end. At least a portion of the housing may be configured to selectively move radially with respect to the bundle of hollow gas exchange fibers. An oxygenator may include a rigid housing extending from a first end to a second end, a flexible housing disposed within the rigid housing, and a bundle of hollow gas exchange fibers extending between the first end and the second end within the flexible housing. At least a portion of the flexible housing may be configured to selectively move radially with respect to the bundle of hollow gas exchange fibers.
