Apparatus and methods for wireless communication via electrical pulses conducted by the interstitial tissues of the body for an active implantable medical device
First Claim
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 comprising:
- Means for providing digital information to be communicated;
at least one pair of electrodesMeans 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.

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.
