Abstract

A system intended for being at least partly implanted into a living body and comprising at least two modules or devices which are interconnected by a communication transmission channel, at least one of said modules being provided with transmitting and receiving means for a bidirectional exchange of information with at least one further module and at least one other module of which being provided at least with receiving means or transmitting means for receiving information from at least one further module or for transmitting information to at least one further module, respectively. Within the intracorporal region, said communication transmission channel is wireless. It includes the ion medium of the intra and extracellular body liquids and provides for an electrolytic-galvanic coupling between two or more implantable modules and/or between at least one implantable module and external skin electrodes intended for connection to an external module. The exchange of information is effected by modulated medium frequency signals in the frequency range from 10 to 100 kHz which signals are passed through said communication transmission channel.
