Zusammenfassung:Improvements to integrated blood pump/oxygenator (120) having a rotating hollow fiber bundle (127) assembly that both oxygenates, and pumps blood, are provided. An inner member arranged along a central axis of the device accelerates blood entering the fiber bundle (127) to reduce micro-bubble generation, and blood trauma. Shearing loads imposed on the fiber elements of the fiber bundle (127) are reduced by the addition of a reinforcement structure, while the gas flow path is configured to reduce flooding, and loss of oxygenation efficiency due to occasional rupture of fiber elements.
