The first shunts were developed in the mid 1950's by a man whose sone died from hydro. They have advanced a great deal sinc that point and as suecr says the programmables have been around since the 1990's. There are currently at lease 26 different types of shunt in se around the world for many different types of problems. Many of us are alive today as the result of them.

I wish you all the best in your adventures with hydro and any of the other problems that sometimes come along with it. It is hard sometimes but we just keep plugging along and deal with what we have to when we have to.

Sue you made me smile when you remembered that I was a patient at BWH. We haven't talked in months. It was nice to see that you remembered.

Be talking in here later no doubt

Regards for now to all
