The proGAV is a pressure differential valve that can have its opening pressure adjusted. The proSA is a gravity activated valve whose resistance varies iwht its orientation to the earth’s gravitational field. Ventriculoperitoneal (VP) shunts are a device used to shunt cerebrospinal fluid in the treatment of hydrocephalus. As the name suggests, a catheter is placed with its tip in the ventricle.

Presented as a 2019-06-07 The programmable CSF shunt valve has become an important tool in hydrocephalus treatment, particularly in the NPH population and in pediatric patients with complex hydrocephalus. The purpose of this study is to provide a single reference for the identification of programmable shunt valves and the interpretation of programmable shunt valve settings.

A lower pressure setting means more CSF is being drained. Strata ® adjustable pressure valves are part of a shunt system used to treat the symptoms of hydrocephalus. A shunt redirects excess cerebrospinal fluid in the brain to another part of the body, allowing the brain’s enlarged ventricles to return to a more normal size.

With regard to MRI, the product insert for the CODMAN HAKIM Programmable Valve states: "Note: Remember to verify valve pressure setting after an MRI." DELTA SHUNT ASSEMBLY The Delta Shunt Assembly (Medtronic Neurosurgery, Goleta, CA) combines the Delta valve with an integral, open-end, radiopaque peritoneal catheter.
