CALGARY -- A Calgary man is calling out Apple after his new iPhone 12 caused interference with his medical implant which included a shock. “It was like getting tasered. I fell down, it was it was excruciating and shocking, literally shocking pain,” said Matthew Harckham. His implant, called the Prodigy MRI Implantable Pulse Generator, is manufactured by U.S.-based company Abbott. It provides 'neuromodulation' — the device stimulates his spine with a gentle current to ease chronic pain after he was struck by a bus in 2003. The device is controlled externally with a device that he waves over a 'pocket' in his lower abdomen, while the pulse is sent to his spine.
