First Claim
1. A system comprising:
- 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; and
a wireless signal detector including a near-field inductive second telemetry circuit coupled to the power connection module, to control the conductivity state of the power connection module according to information detected in a wireless near-field inductive signal.

Abstract
An implantable medical device includes a radio-frequency (RF) telemetry circuit connected to an energy source through a power connection module to obtain power when a user initiates an RF telemetry session. After the session is completed, the power connection module shuts off the at least one portion of the RF telemetry circuit. Power-on examples include a wireless telemetry activation signal received by a low power radio receiver in the implantable device, a physical motion detected by an activity sensor therein, an activation of an inductive telemetry circuit therein, a magnetic field detected by a magnetic field detector therein, and/or a telemetry activation signal detected by a sensing circuit included therein. Power-off examples include a wireless termination signal received by the implantable device, a delay timeout after the session, and/or a signal received by an inductive telemetry circuit in the implantable device.
