Hi Michaelms,
Welcome to LBT! I'm coming up on three years banded and am settling in for the long haul. The band is designed to be permanent, but like any implanted medical device things may happen that require maintenance or removal/replacement. It's only been in use for 15 years worldwide so there's not a large body of information on the very-long-term, but I'm hoping to find out!
As far as what happens when you reach ideal weight, you can always have the band adjusted if you're having any trouble getting in enough calories. (That's the beauty of it!) In my experience, as I lose weight I lose a bit of restriction along with it, so I don't expect to have any problems at all getting in enough calories.
When and if the band is removed, there is unlikely to be any long-term complications. The shape of the stomach may have been permanently altered, but it will still work the same way as before banding since no systems have been altered. There are several people on this board who have had their bands removed, and as far as I know none of them are dealing with any resulting complications.
Keep asking questions! :biggrin1:
