Abstract:
A power source longevity monitor is configured for an implantable medical device. An energy counter counts the amount of energy used by the implantable medical device. A voltage monitor monitors the voltage of the power source. A calculator predicts the power source longevity using the energy longevity estimate and the voltage longevity estimate.
Abstract:
This disclosure describes techniques for generating an elective replacement indication (ERI) for an implantable medical device having a non-rechargeable power source. A signal may be sampled that is indicative of a characteristic of the power source. Measurement logic may be configured to obtain samples of a signal indicative of a characteristic of the power source. A control circuit may be configured to determine when a first sample of the signal having a first predetermined relationship to a first threshold is received, and to initiate issuance of an elective replacement indication if a predetermined period of time elapses between receipt of the first sample and receipt of a second sample of the signal having a second predetermined relationship to a second threshold.
