The TSA has some information for screening of medical devices on their website. In general, items go thru the X Ray machine.

You can also TSA qiestions. There are contact points for resources here:

I would contact the company that makes your devices to see what information they have regarding travel and whether the devices can go thru the metal detector or not.
Your airline should have AEDs actually on the plane (there was a 2001 rule that required them to be on aircraft within 2 years of that date). I would notify your specific airline that you are traveling with them and will be carrying them on. Medical devices fo not count toward your baggage/carry on allowance.
Regarding WDW resorts or the cruise, I can’t think of anything to check or inform.
You would go thru security for the cruise similar to air travel.
For WDW parks, you will go thru security, but they are mostly looking for weapons, glass bottles and alcohol. You will need to remove anthing underneath a stroller for screening. You might need to explain what it/they are - just general, medical devices. Don’t need to get into detail.
If you have stroller/strollers, go to Guest Relations to get a stroller as wheelchair tag. That will allow you to bring the stroller(s) in lines/attractions where strollers are not allowed. Wheelchairs do not require any tag or permission to use in lines.
You can also ask about Disability Access Service (
DAS) at Guest Relations. This is basic info from Disney about DAS and there is a thread about DAS stuck near the top of this board.
