Abstract
Systems, methods, and devices for activating an implantable medical device from a low-power sleep state are provided. One method includes receiving a wake-up signal at a receiver device from a transmitter device. The wake-up signal includes a series of pulses having a pulse pattern encoding a predetermined wake-up code. The wake-up signal is transmitted via intracorporeal communication of electrical pulses conducted by interstitial tissues of a patient'"'"'s body. The method further includes extracting the wake-up code from the wake-up signal and determining whether the wake-up code corresponds to a stored wake-up value. The method further includes, in response to determining that the predetermined wake-up code corresponds to the stored wake-up value, switching at least one active circuit element of the receiver device from a lower-power sleep state into a higher-power operational state.
