Title: Chronic peritoneal dialysis sac

Abstract: An internal peritoneal dialysis prosthesis and method employing an abdominal sac adapted to be retained in the abdominal region of a patient's body and including dialysate therein for permitting unconcentrated urine within the peritoneal region to pass through a semi-permeable membrane wall of the abdominal sac. The unconcentrated urine within the abdominal sac is directed for subsequent excretion from the patient's body via a reservoir in liquid communication with the abdominal sac. In a preferred embodiment, the abdominal sac includes a central region and lobes of semi-permeable membrane extending from the central region. The lobes are constructed to preferably extend between folds of bowel and mesentery to increase the interface area between the sac and abdomen, and maximize diffusion and ultrafiltration of urine from the mesenteric parentis and peritoneum.
