Metabolic waste products from the blood of a patient are removed by pumping dialysis solution into the peritoneal cavity of the patient, and then (a) removing a portion of the dialysis solution from the peritoneal cavity which portion may vary from 1 percent to 90 percent of the total amount of dialysis solution administered to the peritoneal cavity and, (b) "cleaning" (removing metabolic waste products) this solution either through a dialyzer or by means of sorbent modules and then returning this same (cleansed) fluid into the peritoneal cavity. This cycle is repeated again and again until the desired amount of metabolic waste products are removed.

Another subcutaneous peritoneal catheter is shown in the U.S. patent application Ser. No. 594,374 filed July 9, 1975, since abandoned in favor of Continuation-in-part Application Ser. No. 768,520 filed Feb. 14, 1977. This application discloses a dual catheter, two needle system devoted to cross-flow peritoneal dialysis, whereas the present invention is directed to single catheter and single needle system operating on a push-pull principle.
