A specially designed silicone medical device consisting of a pump chamber with two catheters, the Denver shunt transfers fluid from the peritoneal space to the circulatory system. This allows the patient to maintain the critical protein and nutrients in the peritoneal fluid, and normal flow through vital organs. Double-valved shunts meet the needs of most patients. They provide ample flow rates and a second valve. The second valve serves as a check valve that helps prevent the reflux of blood into the venous catheter when the shunt is manually pumped.
