I would give Medtronics corporate (the main phone #) a call. I am familiar with them and they are very nice. I'm sure they have a development dept. that deals with something like this and would be interested, especially in today's electronic era, and I think it's a good idea.
Do you have a rep. that you see? If so, perhaps contacting him/her could also refer you to a person to contact as well.
Let us know what you hear. You caught my curiosity now. :-)
Hi, Viva Medtronic - "Keeping me well since 2010!"
Be interested to know how your enquiry turns out. I have a CRT-D and am on home monitoring but only downloads via the telephone line once a week onto a Server at my local Heart Hospital. I too would prefer a smartphone link and ditch the landline if technology was available.
I would not be surprised if Medtronic modified the existing rfid chip to communicate with some phones via WiFi.
