Jim, Glad to hear you are OK. I change my controller battery every 6 months - Jan/July BUT don't carry it with me unless I am traveling. Thanks for giving me a reason for popping it in my purse. Hope you wear a medic alert bracelet.

FYI
External defibrillation may damage a Neurostimulator. If external defibrillation is necessary and the situation permits, follow these precautions to minimize current flowing through the neurostimulator and lead-extension system:
Position defibrillation paddles as far from the neurostimulator as possible.
Position defibrillation paddles perpendicular to the implanted neurostimulator-lead system.
Use the lowest clinically appropriate energy output (watt seconds).
Confirm neurostimulation system function following any external defibrillation.
