Abstract
An active implantable medical device including bidirectional communications between a generator and sensors or actuators located at the distal extremity of a lead. A lead (14) is connected at its proximal end to a generator (10) and has at the distal end electrodes (38, 42) able to come in contact with surrounding tissues. A two-wire connection (34, 36) connects these electrodes to the generator. The lead incorporates transducers (24, 26) of sensor or actuator type. The generator includes circuits for sending and receiving digital data (46,48,50,54,56) capable of producing instructions to one of the transducers and to receive and decode information from one of the transducers in response to a specific instruction produced by the generator. The transducer is able to receive, decode and carry out the aforementioned controls, as well as send data in response.
