1. A peritoneal dialysis system comprising:
- a reservoir containing dialysate comprising an osmotic agent for infusion into a peritoneal cavity;
an implantable pump having an internal battery that is inductively chargeable, the implantable pump adapted for fluidic communication with the peritoneal cavity and a bladder;
a drainage conduit adapted for coupling between the peritoneal cavity and the implantable pump;
an exit conduit adapted for coupling between the bladder and the implantable pump, wherein the implantable pump is configured to pump the dialysate comprising the osmotic agent from the peritoneal cavity through the drainage conduit into the bladder through the exit conduit; and
an implantable controller associated with the implantable pump, the implantable controller including a clock and configured to actuate the implantable pump to meter movement of the dialysate between the peritoneal cavity and the bladder based on an output of the clock.

Abstract
A device and methods for treating renal failure are disclosed. One embodiment of the device is an implantable peritoneal dialysis device. When in use, the device can have a semi-permeable reservoir implanted in the peritoneal cavity. The reservoir can receive blood waste and drain through one or more conduits, via a pump, to the biological bladder. Solids and/or a solution benefiting dialysis can be pumped to the reservoir and/or implanted in the peritoneal cavity.

11. A method of performing peritoneal dialysis on a subject having a peritoneal cavity and a bladder, the method comprising:
-
implanting a battery powered, inductively rechargeable pump within the subject; introducing a dialysate comprising an osmotic agent into the peritoneal cavity from a reservoir; pumping the dialysate from the peritoneal cavity into the bladder using the pump; monitoring an output of a clock using an implantable controller associated with the pump; and adjusting a rate at which the dialysate is pumped between the peritoneal cavity and the bladder responsive to the output of the clock. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
