Active implantable medical device including a means for wireless communication via electric pulses conducted by the interstitial tissue of the body

摘要

The device has a wireless human body communication unit communicating with another medical device through signals formed of electric pulses to be driven through interstitial tissues of body. Switches (44, 48) generate a train of pulses formed of a series of electric pulses. Modulating unit modulates the train of pulses through digital information produced by the device, where the pulses are biphasic pulses comprising positive and negative alterations. An injection unit injects biphasic current pulses produced by constant current source (42) in the switches between electrodes (22, 24).
