After watching www.ted.com/talks/tal_golesworthy_how_i_repaired_my_own_heart.html
and thinking for a bit, it does feel like a valve (Like LES) should be a straightforward concept.
May be it is because I am an engineer, but am I alone in wondering why in 2012 we can't make a valve ? No disrespect, but Fundo feels like an OVERKILL for a simple valve, doesn't it ?
WHAT IS YOUR IDEA OF AN IDEAL EXTERNAL VALVE (realistic of course) ?
My idea is a post-implant pressure adjustable device operated by a remote control:
open it when you need to eat/burp, close otherwise. In time, it can be improved so that close/
open are triggered based on esophageal contractions.
