A cerebral shunt is a device permanently implanted inside the head and body to drain excess fluid away from the brain. They are commonly used to treat hydrocephalus , the swelling of the brain due to excess buildup of cerebrospinal fluid (CSF).
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.
Each of the types of shunts listed above can be composed of a tube or catheter and various types of valves, although they can just be composed of the tubing or catheter. Below is a list of valves that are used in lumbar–peritoneal shunts (LP shunts) and Cerebral shunts (for a more detailed list of the types of valves see type of valves): Delta
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the medical specialty that focuses on the surgical treatment or rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nervous system, and cerebrovascular system.

The current version of ShuntCheck was developed in 2011-2012 funded by grants from the National Institute of Health [17] [18] [19] and was cleared by the US FDA in 2013. [1] ...
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 ...
Here, pulses are emitted to the brain tissue in a fixed frequency (often 130 Hz) without sensing brain signals or other forms of a steering signal.It took until the 2010s, after a demonstration of efficacy of aDBS in the macaque by the team of Hagai Bergman in 2011, [10] the first in-human application of aDBS was carried out by the team of ...
Shunt surgery was introduced in 1949; initially, ventriculoperitoneal shunts were used. In 1971, good results were reported with lumboperitoneal shunting. Negative reports on shunting in the 1980s led to a brief period (1988–1993) during which optic nerve fenestration (which had initially been described in an unrelated condition in 1871) was ...
