APPARATUS AND METHODS FOR TREATING INTRACORPOREAL FLUID ACCUMULATION
First Claim
1. A fluid management system comprising:
- 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;
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
A fluid management system for the treatment of ascites, pleural effusion or pericardial effusion is provided including an implantable device including a pump, control circuitry, battery and transceiver; a charging and communication system configured to periodically charge the battery and communicate with the implantable device to retrieve performance data; 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 implantable device includes a number of features that provide automated movement of fluid to the bladder with reduced risk of clogging, with no patient involvement other than occasional recharging of the battery of the implantable device. The monitoring and control software is available only to the treating physician, such that the physician interacts with the implantable device via the charging and communication system.
