It was the launch of the Endobarrier over here that prompted me to have my surgery. However, there was only one place doing it and I couldn't afford it. I volunteered for clinical trials but never heard anything. My gp referred me to my surgical team to see if they were going to do them, as he had never heard of it. They weren't going to do it, but recommended me for a bypass.
I recall it's not designed to stay in for good, so you need to ask about this to see what the instance of regain is once it's removed. It's certainly not invasive and is an outpatient procedure.
Good luck-and do keep us posted. I think more and moe people will have it as it becomes more widely available.
