Denver Ascites Shunt
The Denver Ascites Shunts are provided in two configurations.
-
All of the Denver Ascites Shunts are constructed from medicalgrade silicone.
-
Each shunt consists of a fenestrated peritoneal catheter, a venous catheter, and a flexible pump chamber containing either one or two miter valves.
-
The heart of the shunt is the flexible pump chamber. The miter valve(s) contained within the pump chamber permit flow in only one direction.
-
When the pressure in the peritoneal cavity is approximately 3 cm water higher than the central venous pressure, the valves open and permit flow through the shunt.
-
In a double-valved shunt, the second valve serves as a check valve that helps prevent reflux of blood into the distal end of the venous catheter when the shunt is manually pumped. In a single-valved shunt, reflux is prevented by manual occlusion of the venous catheter.
-
The valves are made deliberately asymmetrical, causing them to be self-cleaning.

Indications
Peritoneo-venous shunting is indicated for patients with:
• chronic liver disease whose ascites has not responded to surgical correction of their portal hypertension nor to standard medical management.
• persistent ascites who are not considered candidates for portal-venous shunting.
• persistent ascites that is non-responsive to standard medical management.
• primary or metastatic intra-abdominal neoplasms with massive ascites to help relieve intraabdominal pressure.
Contraindications
• peritonitis
• possible non-sterile ascitic fluid or intra-abdominal infection
• acute tubular necrosis or primary renal failure
• extremely high bilirubin and/or creatinine levels

Pleural Effusion Shunt
Denver Pleural Effusion Shunt
-
The entire shunt is constructed from medical-grade silicone rubber.
-
The Denver Pleural Effusion Shunt consists of a fenestrated pleural catheter, a flexible pump chamber containing two miter valves, and a fenestrated peritoneal catheter.
-
The heart of the system is the valved pump chamber. This pump chamber is used by the patient or care giver to transfer the pleural fluid into the peritoneal cavity.
-
The valves are made deliberately asymmetrical, causing them to be self-cleaning as the system is pumped.
-
The second valve serves as a check that helps prevent reflux of liquid into the peritoneal catheter when the shunt is manually pumped.

Indications
The Denver Pleural Effusion shunt is indicated for use in patients with:
• chylothorax
• intractable aseptic pleural effusion
Contraindications
The Denver Pleural Effusion Shunt is not designed for pleurovenous application.
Pleuro-peritoneal shunting is contraindicated in patients with infected pleural fluid and in patients suspected of having intra-abdominal infections such as diverticulitis.
