Abstract:
1. A method for dialysis of blood, comprising: providing a dialyzer comprising: a plurality of semipermeable membrane sheets; and a plurality of flow separators, the semipermeable membrane sheets and flow separators arranged in alternating configuration and coupled into a laminae stack defining a plurality of parallel microchannels layers, each microchannel layer comprising a plurality of first microchannels and a plurality of second microchannels, each first microchannel and each second microchannel being defined by two of the plurality of semipermeable membrane sheets, the first microchannels and the second microchannels of each microchannel layer being in fluid communication with each other via one of the plurality of semipermeable membrane sheets therebetween, the blood-handling apparatus in fluid communication with the first microchannels, the dialysate-handling apparatus in fluid communication with the second microchannels; supplying the first microchannels with blood at a first end of the first microchannels; supplying the second microchannels with dialysate at a second end of the second microchannels; withdrawing blood from the first microchannels at a second end of the first microchannels; and withdrawing dialysate from the second microchannels at a first end of the second microchannels.
