It is already being tested in the US. I saw this back in October when I was researching surgeons. At first I thought it would be great but then I read no not for sustained weight loss! However, what it will be used for is to help people who are too overweight for weight loss surgery to lose their weight safely in order to undergo the surgery that they need. Also, used for people who may only have 20 lbs to lose! Not everyone is a candidate for WLS...some people are still very overweight but don't fit the correct BMI! I had to hit 233 lbs before I was eligible for the band and for insurance to cover it! It does not have to be removed at the end of 3 months. It is what's based on what your dr tells you. Yes, I think it's a little bit stupid but surgery isnt for everyone.
