Not that I know of, but if someone has please share! I think it's relatively new for use with Barrett's. I am more familiar with Radiofrequency's use to treat nerve pain.
These studies look rather promising, especially because there's really been no other option other than surgery, and/or "watchful waiting". I'd prefer not to wait for things to get worse if I can help it!
Griff - do you have Barrett's?
BTW I called one of the GI specialist groups in my area today and they are doing the procedure, but they said before insurance would pay you had to have tried two different ppi's, and have some level of dysplasia.
