LVAD Controller Exchange Demonstration

In this video, providers from the Mass General Hospital Corrigan Minehan Heart Center demonstrate step-by-step instructions for how to change a HeartMate 3 left ventricular assist device (VAD) controller to the backup system controller.

I carry an LVAD and needed to change the percutaneous cable because I have worn the thing for so long that I had holes all along of it.
7 holes with the webbing and inside cables clearly visible....
I covered them up each time with eletrician's tape but they kept on coming back.
I would be interested to know how many other LVAD patients this has happened to ?
My hospital told me 1) NEVER to touch/fiddle with the controller 2) NEVER to undo the cable.
The finally changed both the controller AND the percutaneous cable after 2 years...
Is this video suggesting that patients are expected to do this manipulation if needed ?
I would also be interested to know how many patients have had to change the controller and WHY ?
Anybody's answer would be well appreciated as the medical team where I live are useless. They do NOT communicate and the cardiologists are worse. They hide and simply don't answer any of my questions.
Many thanks

So what you’re telling me is that we’re doing Indiana jones with this stuff.
