  • Antithrombogenic hollow fiber membranes and filters
    Patent number: 8877062
    Abstract: The invention relates to extracorporeal blood circuits, and components thereof (e.g., hollow fiber membranes, potted bundles, and blood tubing), including 0.005% to 10% (w/w) surface modifying macromolecule. The extracorporeal blood circuits have an antithrombogenic surface and can be used in hemofiltration, hemodialysis, hemodiafiltration, hemoconcentration, blood oxygenation, and related uses.
