Can some of this tech be used for hydro ?

I subscribe to FDA device approval list.  Interesting development for people with seizures.

"What is it?  The RNS System helps reduce the frequency of seizures in epilepsy patients who have frequent, disabling, partial-onset seizures and have not responded well to medications.  It consists of a stimulator implanted in the skull under the scalp and leads implanted in the brain."
