A patient with an implanted defibrillator experiences a sudden shocked in the shower event; hospital records show an EKG distortion yet clinicians cannot change the device timing because manufacturers lock the firmware and send salespeople instead of engineers. The device is regulated as a Class III device in Germany but certification still allows non‑updatable Bluetooth stacks. A free‑software solution exists — OpenAPS artificial pancreas — and changing a single timing variable would likely remove the malfunction.
