I am sorry you have to deal with a damaged pump, but Medtronic absolutely advises not to subject their pumps to x-ray machines (which includes not putting them on the conveyor belt / scanner for hand luggage, as well as not going though the full-body scanners). Only the standard metal detector gates are OK. It’s super annoying, but I learned (also from experience a long time ago) to always request the manual pat-down, regardless of how many TSA staff members roll their eyes at me.
