Apparatus and methods for wireless communication via electrical pulses conducted by the interstitial tissues of the body for an active implantable medical device

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 comprising:

• Means for providing digital information to be communicated;
• at least one pair of electrodes
• Means for generating a pulse train containing a succession of electrical pulses, said generator means comprising a regulated current source, wherein said pulse train comprises a train of biphasic current pulse 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;
• wherein the modulation means further comprises means for modulating a temporal interval between the pairs of consecutive biphasic current pulses of the biphasic pulse train.
