APPARATUS AND METHODS FOR TREATING INTRACORPOREAL FLUID ACCUMULATION
First Claim
1. A fluid management system comprising:
- an inflow catheter comprising an inlet end and an outlet end;
an outflow catheter comprising an inlet end and an outlet end adapted to be positioned in a sink cavity;
an implantable pump coupled to the outlet end of the inflow catheter and the inlet end of the outflow catheter, the implantable pump comprising a housing containing a positive displacement gear pump coupled to an electric motor and a controller coupled to a battery, the controller programmed to automatically activate the motor and gear pump to move fluid from the inlet end of the inflow catheter to the sink cavity responsive to operational parameters stored at the controller; and
a non-transitory computer readable medium programmed with instructions that, when run on a computer, cause a graphical user interface of the computer to visually display information indicative of status of the implantable pump wirelessly transmitted from the implantable pump, the computer readable medium further configured to store adjusted operational parameters responsive to user input.

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.

17. A method for treating intracorporeal fluid accumulation, the method comprising:
-
storing operational parameters at a controller of an implantable pump; pumping fluid from an inflow catheter coupled to the implantable pump to an outflow catheter coupled to the implantable pump responsive to the stored operation parameters; wirelessly transmitting status information data from the implantable pump to a computer; displaying information indicative of status of the implantable pump based on the status information data; wirelessly transmitting adjusted operation parameters from the computer to the implantable pump; storing the adjusted operational parameters at the controller of the implantable pump; and pumping fluid from the inflow catheter to the outflow catheter responsive to the stored adjusted operation parameters. - View Dependent Claims (18, 19, 20, 21)
