Assignee: PACESETTER, INC.
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 0:
1. An implantable medical device (IMD), comprising:
memory configured to store program instructions;
a processor configured to execute the program instructions;
circuitry electrically coupled to the processor, the circuitry and processor configured to perform one or more tasks in connection with at least one of i) collecting signals indicative of physiologic activity, ii) analyzing the signals collected, iii) delivering a therapy, or iv) communicating with an external device;
a battery configured to supply energy to the circuitry and the processor in connection with performing the one or more tasks; and
a monitoring circuit coupled to the battery, the monitoring circuit configured to measure an actual energy usage from the battery, the actual energy usage representing at least one of a current draw from the battery during the corresponding tasks or a voltage measurement across the battery;
wherein the circuitry and processor are further configured to:
calculate a projected energy usage from the battery in connection with the corresponding tasks; and
determine when an early battery depletion (EBD) condition exists based on the projected energy usage and the actual energy usage.
