A fluid management system (10) for the treatment of ascites, pleural effusion or pericardial effusion is provided including an implantable device (20) including a pump (95), control circuitry (70), battery (74) and transceiver (76); a charging and communication system (30) configured to periodically charge the battery and communicate with the implantable device to retrieve performance data; and monitoring and control (40) 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.
