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.
