IMPLANTABALE NEUROSTIMULATOR-INITIATED STATUS NOTIFICATION
First Claim
1. An implantable medical device, comprising:
- a power source configured for storing energy;
monitoring circuitry configured for monitoring a quantity of the stored energy in the power source; and
control circuitry configured for generating a battery status signal based on the monitored quantity of stored energy;
telemetry circuitry configured for transcutaneously sending a communication initiation signal to an external device to initiate communication with the external device, and sending the battery status signal to the external device; and
a housing containing the power source, the monitoring circuitry, the control circuitry, and the telemetry circuitry.

Abstract
A medical system comprises an implantable medical device having a power source, the implantable medical device configured for monitoring a quantity of the stored energy in the power source, generating a battery status signal based on the monitored quantity of stored energy, and for transcutaneously transmitting a communication initiation signal and the battery status signal. The medical system further comprises an external device configured for transcutaneously receiving the communication initial signal and the battery status signal from the rechargeable implantable medical device, changing from a relatively low energy consumption state to a relatively high energy consumption state in response to the received communication initiation signal, and for generating a user-discernible signal in response to the received status signal.
