  • Two stage hemofiltration that generates replacement fluid
    Patent number: 7531094
    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.

  • Vortex-enhanced reverse osmosis filtration device and methods
    Patent number: 7425265
    Abstract: Preferred aspects of the present invention relate to advances in rotating, vortex-enhanced reverse osmosis filtration. More particularly, the filtration device and methods incorporate a rotational drive mechanism adapted to use the flow of pressurized process fluid to cause rotation of a rotor within a housing, thereby creating shear and Taylor vortices in the gap between the rotor and housing. The improvements disclosed herein facilitate continuous use of vortex-enhanced filtration for prolonged periods of time.
