Patent number: 12220515Abstract: 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.Type: GrantFiled: January 15, 2019Date of Patent: February 11, 2025Assignees: University of Pittsburgh—Of the Commonwealth System of Higher Education, Mississippi State UniversityInventors: William J. Federspiel, Shalv Madhani, Ryan A. Orizondo, Peter Drew Wearden, Brian Joseph Frankowski, Alexandra May, Gregory Burgreen

Publication number: 20240165313Abstract: An extracorporeal system for lung assist includes a housing having a blood flow inlet in fluid connection with a pressurizing stator compartment within the housing. A fiber bundle compartment within the housing is above and in fluid connection with the pressurizing stator compartment via a flow channel formed within the housing and extending from the pressurizing stator compartment to an inlet manifold of the fiber bundle compartment. A blood flow outlet in is fluid connection with an outlet man fold of the fiber bundle compartment. The blood flow inlet extends through the housing parallel to a plane of rotation of an impeller in the pressurizing stator compartment. The blood flow inlet turns to deliver blood into a central portion of the impeller. A has inlet is in fluid connection with the housing and in fluid connection with inlets of the plurality of hollow gas permeable fibers of a cylindrical fiber bundle positioned within the fiber bundle compartment.Type: ApplicationFiled: February 1, 2024Publication date: May 23, 2024Inventors: Shalv Madhani, Brian Joseph Frankowski, William J. Federspiel, Gregory Burgreen, James F. Antaki
