1. A system for communicating information between a first medical device and a second medical device comprising:

  • a first transducer connected to said first medical device;

    a second transducer connected to said second medical device;

    each of said transducers including a pair of electrically separated electrodes;

    means for imposing an electrical potential across one said pair of electrodes of one of said transducers and modulating said electrical potential according to said information to be communicated, to generate a modulated electric field;

    said other of said transducers being disposed within influence of the modulated electric field; and

    means having inputs connected to said pair of electrodes of said other of said transducers for amplifying an electrical potential sensed between said pair of electrodes of said other of said transducers.
