Methods and apparatuses for implantable medical device telemetry power management

摘要

A method comprises connecting at least one portion of a far-field radio-frequency (RF) first telemetry circuit in an implantable medical device to an energy source through a power connection module, detecting information included in a first predetermined wireless signal, changing a conductivity state of the power connection module when the information in the first predetermined wireless signal is detected to couple power to the at least one portion of the first telemetry circuit, detecting a second predetermined wireless signal, and changing a conductivity state of the power connection module to decouple power to the at least one portion of the first telemetry circuit when the second predetermined wireless signal is detected and the first telemetry circuit enters an idle state.

1. 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; anda 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.
