1. An active implantable medical device, comprising means for wireless intracorporeal communication with at least one other active implantable medical device via electrical signals conducted by the interstitial tissues of a patient'"'"'s body (12, 14) comprising:

  • Means for providing digital information to be communicated;

    at least one pair of electrodes (22, 24);

    Means for generating a pulse train containing a succession of electrical pulses, said generator means comprising a regulated current source (42), wherein said pulse train comprises a train of biphasic current pulses produced by said regulated current source, each biphasic pulse comprising a positive and a negative alteration;

    Means for modulating the pulse train by said digital information; and

    Means for injecting the modulated pulse train between said at least one pair of electrodes (22, 24).
