Overview
Delta valves minimise overdrainage of cerebrospinal fluid (CSF). They’re part of a shunt system used to treat the symptoms of hydrocephalus. A shunt redirects excess CSF in the brain to another part of the body, allowing the brain’s enlarged ventricles to return to a more normal size.
Key Features
- Delta Chamber allows pressure in the brain to be maintained within a certain range, regardless of body position.
- Nonmetallic design won’t be affected by magnetic resonance imaging (MRI).
- Reservoir dome allows your doctor to sample cerebrospinal fluid and test shunt function.
- Contoured reservoir base mimics the curvature of the skull.
Placement
The valve is placed behind the ear or near the top of the head. It’s attached to a ventricular catheter on one side, which is placed in the ventricle of the brain and a distal catheter on the other, which goes to the peritoneal cavity or right atrium of the heart.
