The Wade-Dahl-Till (WDT) valve is a cerebral shunt developed in 1962 by hydraulic engineer Stanley Wade, author Roald Dahl, and neurosurgeon Kenneth Till. [1] [2] In 1960, Dahl's son Theo developed hydrocephalus after being struck by a taxicab. A standard Holter shunt was installed to drain excess fluid from his brain.
An analysis of 17 studies published over the past 30 years regarding children with CSF shunt infections revealed that treating with both shunt removal and antibiotics successfully treated 88% of 244 infections, while antibiotic therapy alone successfully treated the CSF shunt infection in only 33% of 230 infections.

Nearly all implants require open brain surgery, but, in 2019, a company called Synchron was able to successfully implant a brain–computer interface via the blood vessels. There have been a number of advances in technological spinal cord injury treatment, including the use of implants that provided a “digital bridge” between the brain and ...
For the most part, the surgeries would go well initially, but there was a general theme of subsequent deterioration and even death years after the surgery. As a result of the complication risk and the introduction of new anti-seizure medications, the popularity of the procedure began to decline in the 1950s. [ 4 ]
Lampert, who has performed over 100 implant-removal surgeries for women of all ages, believes another reason behind the surge in interest is that implants, first developed in the ’60s, have ...
Hydrocephalus is a condition in which cerebrospinal fluid (CSF) accumulates in the brain, potentially leading to brain damage and death. It is corrected by a shunt which drains excess CSF from the brain to the abdomen. Shunts fail, typically by obstruction – a life-threatening medical condition requiring the surgical replacement of the shunt.
