Abstract
An integrated blood pump/oxygenator having a rotating hollow fiber bundle assembly that both oxygenates and pumps blood is provided that includes a plurality of partitions disposed within or about the fiber bundle assembly to lengthen the flow path of blood passing through the fiber bundle. Alternatively, or in addition, blood flow paths may be lengthened and oxygenation improved by providing internal recirculation paths within the pump/oxygenator, which also advantageously may be used to reduce blood trauma caused by stagnation nearing moving parts and heat build-up.
