Medtronic's RestoreSensor uses an accelerometer to direct a neurostimulator to neutralize pain signals in the brain.
Medtronic's RestoreSensor uses an accelerometer - a motion sensor used in iPhones and Nintendo Wii remotes - to direct a neurostimulator "to send an electric charge to neutralize pain signals in the brain." This video, featured on CBC News' website, highlights the technology in further detail.
According to an accompanying article, "Older neurostimulation technologies didn't respond well to movement, leaving patients prone to shocks or discomfort."
"In contrast, the new technology is programmed to adapt to the changing position of the patient and deliver a smooth current," said Dr. Krishna Kumar of Regina, one of the few Canadian doctors to use it.
