So you have a wireless interface for the non-able-to-kill-you stuff. But if you're having to change the code of something that's been implanted, you've already

  For example, I think pacemakers can set the range of acceptable heart rates by radio. So now, you have to have logic checking that it doesn't get set to 0. But what happens if there's a buffer overflow in that checking? Edit: here's a paper demonstrating similar attacks: http://www.secure-medicine.org/public/publications/icd-study.pdf http://www.secure-medicine.org/public/publications/icd-study...

    See, that's an example of something that I do not think should be settable via radio. Maybe inductive or sonic communication. Alternatively, you have the software check the set range, but the hardware (or a second non-connected processor) also checks it separately to make sure it's sane anyways.

  Pacemakers and defibrilators are configured to match an individual patient. Part of that configuration includes what parts of the heart to stimulate. This configuration may need to change as the patient's condition changes. You also need to be able to turn of the pacemaker entirely to monitor how the heart operates without stimulation. You may need to turn of the defibrilator during certain medical procedures...
