Abstract
An active implantable medical device having wireless communication of data via electrical pulses conducted by the interstitial tissues of the body. This device (12, 14) includes a pair of electrodes (22, 24) and generates pulse trains consisting of a series of electrical pulses applied to the electrodes. The pulse train is modulated by digital information (data) that is produced by the device. A regulated current or voltage source (42) is used to generate (44, 48) current or voltage pulses to form the pulse train. Each current or voltage pulse is a biphasic pulse comprising a positive and negative alternation. The biphasic current or voltage modulated by the digital information, is injected between the electrodes (22, 24) and wirelessly communicated.
