ABSTRACT:
The present invention relates to a system for two-stage blood dialysis of a patient. In one embodiment, the system comprises a first filtration device for receiving the blood from the patient and for producing a first filtrate and processed blood. The system further comprises a second filtration device for receiving the first filtrate and producing replacement fluid and waste product. At least one of the first and second filtration devices preferably comprises a Taylor vortex-enhanced blood filtration device.
