Abstract
A fluid management system for moving bodily fluid accumulated due to ascites, pleural effusion or pericardial effusion is provided including an implantable pump coupled to an inflow catheter, an outflow catheter, and optionally an anti-clog catheter. The fluid management system facilitates removal of fluid from a body region, such as the peritoneum, pleural cavity or pericardial sac, where drainage is desired to another body region, such as the urinary bladder or the peritoneal cavity. The system includes clog resistant mechanisms such as clog resistant catheters and/or programmed routines for cycling fluid through inlet catheters in predetermined time intervals and/or responsive to sensed conditions to minimize the risk that inlet catheters become clogged due to, for example, tissue ingrowth and/or solid objects within accumulated fluid.
