Abstract
A system and method for communication between an IMD and an external reader includes bringing a portion of a patient's body into contact with a device-body contact surface of an external reader. The reader transmits a first transdermal carrier wave from the contact surface into the patient's body, where the first carrier wave includes a request for communication with the IMD. The transdermal carrier waves are electrical conductive waves, optical waves, or acoustic waves. Upon detection of the first carrier wave, the IMD transmits a second transdermal carrier wave including a request for an access key from the reader and the reader replies by transmitting a third transdermal carrier wave including the access key back to the IMD. If the access key is valid, the IMD transmits information by radio frequency (RF) in an RF communication mode or a fourth transdermal carrier wave including data from the IMD.
