ABSTRACT:
An implantable valve for allowing the passage of cerebrospinal fluid (CSF) from a ventricle of the brain to a suitable drainage location in the body includes a movable diaphragm, one side of which is in pressure communication with the drainage location of the body and the other side of which is in pressure communication with the epidural spaces. A valve assembly, actuated by movement of the diaphragm in response to increased epidural pressure controls passage of CSF from the ventricles to the drainage area.
