ABSTRACT:
An implantable, anti-reflux, fluid displacement peritoneovenous shunt system. The system includes a double chambered multi-micro-orifice ascites collection device, a magnetically driven pump, and an anti-reflux, anti-backdiffusion, non-thrombogenic catheter tip, all connected by flexible tubing. The shunt is used to transfer fluid from the peritoneum to the cardiovascular system to prevent accumulation of fluid within the peritoneal cavity. The magnetically operated pump may be of either the reciprocating diaphragm or piston type or it may be a rotary driven bellows displacement pump.
