Wade-Dahl-Till valve

The Wade-Dahl-Till valve (pronounced: wade-dahl-til valve) is a type of cerebrospinal fluid (CSF) shunt developed for the treatment of hydrocephalus, a condition characterized by an abnormal accumulation of CSF within the brain.

Etymology

The Wade-Dahl-Till valve is named after its inventors: British actor Roald Dahl, hydraulic engineer Stanley Wade, and neurosurgeon Kenneth Till. Dahl's involvement in the creation of the valve was inspired by his own son's experience with hydrocephalus.

Function

The Wade-Dahl-Till valve functions by diverting excess cerebrospinal fluid from the brain to other parts of the body, thereby preventing the harmful effects of fluid buildup in the brain. Unlike other shunt systems available at the time of its invention, the Wade-Dahl-Till valve was designed to be non-obstructive and to prevent over-drainage of CSF.
