Abstract

Systems and methods for performing hemodialysis to remove metabolic waste from the blood of a patient are disclosed. The systems and methods preferably comprise at least one blood processing apparatus that receives whole blood from a patient. Cellular blood components are removed from the whole blood by hemofiltration, to provide filtered plasma comprising metabolic waste that is substantially reduced of blood cells. The cellular blood components may be returned to the patient. The filtered plasma comprising waste may be removed from the blood processing apparatus through a waste path for further processing in a separate apparatus, or in the same apparatus in a second stage processing procedure to remove metabolic waste components and excess water from the plasma by hemodialysis. At least one of the hemofiltration and hemodialysis processing apparatus comprises a Taylor vortex-enhanced separation apparatus.
