  • Publication number: 20080138792
    Abstract: The present invention is directed to medical devices in which flow is channeled of blood and blood products for the purpose of effecting a chemical exchange to remove desired chemicals from the blood or blood products, and to impart nitric oxide, other smooth muscle relaxant compounds, or other desired chemicals to the blood or blood products to achieve vascular dilatation, reduce adverse reactions, reduce thrombosis, reduce red blood cell injuries, and improve blood handling capabilities. In the present invention, such chemical exchanges occur over semipermeable membranes associated with channeled flow of blood and blood products.
