Abstract
A system for communicating information between a first medical device and a second medical device. A first transducer is connected to the first medical device. A second transducer is connected to the second medical device. Each of the transducers includes a pair of electrically separated electrodes. A means is provided for imposing an electrical potential across one pair of electrodes of one of the transducers and modulating the electrical potential according to the information to be communicated, to generate a modulated electric field. The other of the transducers is disposed within influence of the modulated electric field. A means is provided having inputs connected to the pair of electrodes of the other of the transducers for amplifying an electrical potential sensed between the pair of electrodes of the other of the transducers.
