Patent ID: 8792983

Claim:
A system including: an implantable medical device, the implantable medical device including: a far-field radio-frequency (RF) first telemetry circuit; a power connection module, coupled to the first telemetry circuit, the power connection module including a first conductivity state to connect power to at least a portion of the first telemetry circuit and a second conductivity state to disconnect the power; a wireless signal detector, configured to change the connectivity state of the power connection module to connect power to at least a portion of the first telemetry circuit according to information detected in a wireless signal; and a timer, coupled to the power connection module, to change a conductivity state of the power connection module to disconnect power to at least a portion of the first telemetry circuit after waiting a predetermined period of time after the first telemetry circuit enters a predetermined state that includes at least one of a data transmission idle state and a telemetry establishment failure state.
