ABSTRACT:
A portable artificial kidney designed for continuous use includes a catheter with filter properties. The body portion of the catheter has an infusion duct which opens into the surface of the catheter and is provided with surface channels which are covered by a semi-permeable membrane. Ducts are provided which communicate with the channels. One duct is operatively coupled to a suction pump to remove the filtrate. Another duct serves to supply a rinsing solution and the infusion duct serves to replace the liquid which has been filtered off.
