........I wish there were a bigger 'Heart' I could post to show how much I care
I see that you are certainly going thru a bit of stress and I'm so sorry for this!
Like Mark said, think of the heart pacemaker patients.....
What I've been told is that our SCS units are technically considered "DME" (durable medical equipment).....that is how most insurance companies recognize them.....at least that's the 'category' they have been placed under. Seems a bit odd I know, but there should be guidelines and protocol and I'm sure this will all fall into place and make sense to everyone involved.
SCS's (in general) have been around since the 1960's, so they are nothing 'new'.....of course yours falls in to a category of it's own and you are breaking some new ground per se.......
There should be a manual of sorts that comes with these units which describe exactly what types of frequency and technicalities our units put out. Even our cell phone booklets have fine print in the manuals explaining these issues which seem to be in another 'language' to most of us.

Also, you should have the appropriate identification (via ID card or papers from doctor and/or manufacturer) stating what this medical device is that you have installed in you.

I feel certain that the airlines will handle this (as the others here have stated) as they see aLOT of medical doo dads that alot of folks live with.
I hope you can rest easy on this and just trust it will be ok.
I know airports are intimidating, but once you get seated this first time around, this will alleviate the uneasiness and 'fear of the unknown' that you are facing.
I only wish you have better support from the team that is supposed to be backing you up and help you achieve the goal it is meant to do.......to gain a quality of life! Just try to do your best to keep the communication smooth and be honest about your feelings and I would like to assume that your consultants and Reps would want to do whatever it takes to put this in a good light.........Good Lord, if not for the sake of YOU (which is certainly priority!!)....but for the namesake of this product and who they represent!

I'm certainly lifting this up in prayer for things to be handled smoothly and that all parties involved will feel at ease and everyone fulfill their duty in making this a success.......
I believe this can happen, despite there has been some rocky ground along the way.
Just try to play it cool ok.....don't sweat it.
I'm sittin on the edge of my seat here.....I want this to work out so much!
We're here for you always!

Caring and Caring somemore!
