I had the essure procedure in Salt Lake City 3 months ago and just had the followup test to see if it worked (whether the insertion of the little springs were placed accurately). It did not work. Only one of the tubes had closed. It was a lot of trouble and did produce significant cramping post-surgury. I also was under the impression that the surgury would barely require anesthesia and that I would be awake the whole time. I'm not a chicken, but I got so scared they had to use a more serious sedative. I guess I'd be happy overall if it had worked but since one tube closed doesn't cut it, I'm pretty upset about having chosen this method.
I was concerned that I would somehow feel the inserts, but that was not the case. I have not had any children at all, and maybe if I had it would have been easier to place the inserts. Anyway, carefully consider the failure rate of insertion. Good luck.
