Aaah, now I understand your band forum post better.
I don't have first hand knowledge of this but, in several posts than Nana B has written this week on the lap band forum, this issue has been raised, although the context was somewhat different. The primary issue was whether or not the old 4.0cc bands (the original bands) could be unbuckled and rebuckled. The newer bands (10.0cc and 14.0cc) most definitely can: they were specifically designed to allow that.
It will require a surgery but an unclasped buckle CAN be reset. Regardless of whether it is a old or new technology.
However, you are on the revision forum. Is there something else on your mind? Are you considering a revision to a different surgery? (It's fine that you are here if you are simply interested in getting your band fixed but enquiring minds want to know.)
