1. A method, comprising the steps of:
- inducing a pressure difference across the peritoneum of a patient to increase a total volume of peritoneal fluid in an implanted medical device,performing one or more steps selected from the group consisting of;
1) dialyzing the blood across the peritoneal membrane, wherein peritoneal fluid is conveyed to a space inside of the implanted medical device and then conveyed to a dialysis chamber having a dialysate to reduce the concentration of waste components in the peritoneal fluid conveyed to the implanted medical device;
2) dialyzing the blood across the peritoneal membrane, wherein peritoneal fluid is conveyed to an inside of the implanted medical device and then contacted with a dialysis chamber having dialysate to reduce the concentration of waste components in the peritoneal fluid conveyed to the implanted medical device and using an electrical potential to regenerate the dialysate; and
3) removing excess fluid from the patient by removing at least part of the fluid from the implanted medical device from the patient, andinducing a pressure difference across the peritoneum to decrease the total volume of fluid in the implanted medical device and return fluid from inside the medical device to the patient.

Abstract
The invention relates to a method and device for dialysis and or bulk fluid removal by generating a fibrosis chamber within a body cavity and performing dialysis or bulk fluid removal. An implantable medical device is described having a fibrosis chamber and a pump. A dialysis chamber and an optional electrodialysis unit can further be provided. An additional controller uses sensory feedback to regulate the fluid levels by altering the extracellular fluid retention within the fibrosis chamber. This device can be used for the treatment of patients with chronic kidney disease who may also be suffering from cardiorenal syndrome and hypertension.
