ABSTRACT:
Blood filtration devices and methods of filtering are disclosed. In part, a blood filtration device is provided comprising a housing defining an interior periphery. The device includes a rotating structure mounted within the interior periphery and defining with the housing an annular gap within the interior periphery, an inlet fluid path for allowing a blood product to flow into the annular gap, and the rotating structure including an exterior surface that includes a filter membrane. The filter membrane has a coating thereon comprising an insitu condensation product of a first electrophilically active, high molecular weight polyalkylene oxide and a second high molecular weight bifunctional diamino-polyoxyalkylene oxide derivative.
