Segmental edema is treated by inserting a plasma extraction filter device in a major vein of a body segment or servicing the body segment containing the edemic tissues, and inserting a return catheter in a major artery of the body segment affected or feeding the body segment from which plasma is extracted. Blood plasma and plasma proteins extracted from the edemic body segment through the plasma extraction filter fluids are directed to an ultrafiltration apparatus where plasma water is separated from the plasma proteins. Plasma proteins are returned to the body segment from which the plasma was extracted via the return catheter in the major artery of the subject body segment.

Apparatus and method for selective reduction of segmental intracellular and extracellular edema

An apparatus for treatment of acute and chronic renal disease by continuous passive plasma ultrafiltration includes a plasmapheresis element comprising a catheter and a plasmapheresis filter element secured to the end of the catheter for being implanted in a patient's vena cava or jugular vein, a tube secured to the catheter for receiving and directing blood plasma, a one-way valve for preventing fluid flow from the tube to the catheter, and a container for receiving and collecting the blood plasma. The treatment of the patient is performed by implanting the catheter and plasmapheresis filter element in a patient's vena cava, passing of blood plasma containing the toxins to be removed from the patient's blood supply through the filter element and along the catheter, and collecting and discarding the collected blood plasma.
