Claim Text:
1. A blood filtration apparatus comprising: a source blood conduit configured to fluidly connect a source blood inlet to an inlet of a cross-flow plasma filter; a recirculation conduit configured to recirculate plasma-separated blood from a retentate outlet of the cross-flow plasma filter to the inlet of the cross-flow plasma filter, forming a recirculation loop; a first pump fluidly disposed within the recirculation loop and configured to recirculate plasma-separated blood from the retentate outlet to the inlet of the cross-flow plasma filter, an outlet conduit from the recirculation loop fluidly connected to a first outlet of the blood filtration apparatus; a plasma permeate conduit fluidly connecting a plasma permeate outlet of the cross-flow plasma filter to an adsorption filter for adsorption filtering of plasma permeate; an outlet of the adsorption filter connected to the recirculation loop; and a second pump disposed within the plasma permeate conduit configured to pump plasma permeate between the plasma permeate outlet of the cross-flow plasma filter and the adsorption filter; wherein the second pump is configured to pump a quantity of the plasma permeate into the recirculation loop.
