They can do a tubal ligation on the one tube. The Adiana is so new they've only been doing them a few months in the states. I read the clinical trials & the FDA notes on Adiana. Adiana does not seem to have the risks of perforations, metal coil migration & allergic reactions. I don't like that the FDA made Adiana postpone launching the product. The FDA made the company delay product marketing for a year because they had too many pregnancys in the clinical trials.
Your chances of getting pregnant are greatly reduced by the Novasure but it could happen. I don't know how old you are but I had a bad experience with essure metal coils & after some research, I discovered that at my age there was only about a 1% chance of my becoming pregnant due to my age. Seems dr needed some money or needed to fill his quota for all the free incentives they get if they will perform so many procedures.
Hope you get things worked out
