Systems and methods for treating chronic liver failure based on peritoneal dialysis
First Claim
1. An artificial liver system for use with a patient having a peritoneal cavity and a bladder, the system comprising:
- a reservoir containing a peritoneal dialysis fluid comprising albumin and configured to provide the peritoneal dialysis fluid to the patient'"'"'s peritoneum;
a peritoneal catheter configured for implantation in the patient'"'"'s peritoneum;
a bladder catheter configured for implantation in the patient'"'"'s bladder;
an implantable device comprising a housing containing a positive displacement gear pump coupled to an electric motor and a first controller coupled to a first battery, a first transceiver, and a first inductive charging circuit, the implantable device being configured to pump the peritoneal dialysis fluid in the peritoneum to the patient'"'"'s bladder via the peritoneal catheter and the bladder catheter;
a charging and communication system comprising a second controller coupled to a second transceiver and a second inductive charging circuit, the charging and communication system configured to wirelessly communicate with the implantable device via the first and second transceivers, and to wirelessly transfer energy from the second inductive circuit to the first inductive circuit to charge the first battery;
monitoring and control software configured to run on a computer, the monitoring and control software configured to communicate operational parameters to the implantable device via the charging and communication system to control operation of the motor and gear pump.

Abstract
An artificial liver system for treating liver failure includes a reservoir to provide albumin-containing dialysis fluid to the patient'"'"'s peritoneum, an implantable device including a pump to pump the fluid from the peritoneum to the bladder via respective catheters, control circuitry, battery and transceiver; a charging and communication system configured to periodically charge the battery and communicate with the implantable device to retrieve data reflective of the patient'"'"'s health; and monitoring and control software, suitable for use with conventional personal computers, for configuring and controlling operation of the implantable device and charging and communication system. The monitoring and control software allows a treating physician to remotely adjust the volume, time, and frequency with which fluid is pumped from the peritoneal cavity to the bladder based on the data reflective of the patient'"'"'s health.
