  • Membrane oxygenator with gas exchange fiber lumen access based on fiber effective length
    Patent number: 11541157
    Abstract: Membrane oxygenators useful in a variety of medical situations, including various short-term procedures and relatively longer-term life support, and components of membrane-based oxygenators, such as conditioning modules for exchanging oxygen for carbon dioxide during extracorporeal conditioning of blood, are described. A conditioning module includes a plurality of mats of hollow fibers and a potting material disposed throughout the peripheral edges of the mats to create a circumferential seal that defines a passageway through the plurality of fiber mats having a substantially circular cross-sectional shape. The circumferential seal defines an effective fiber length for each of the hollow fibers. A resisting member is disposed across the proximal ends of at least some of the hollow fibers and is adapted to resist fluid flow into each of the hollow fibers based on the effective fiber length of the particular hollow fiber.
