VNS is made by Cyberonics, I'm not srue if that is what you mean
though. If you put that name in the search, it will bring up there
website. If you call their 800 number, they will send you information
about the Vagal Nerve Stimulator, and that is a start.

THere are also websites about the Stimulator that you can read other
peoples experiences.
