ELECTIVE REPLACEMENT INDICATION GENERATION
First Claim
1. A method for monitoring a power source of an implantable medical device, comprising:
- sampling a signal indicative of a characteristic of the power source;
determining, by a control circuit, when a first sample of the signal having a first predetermined relationship to a first threshold is received; and
issuing, by the control circuit, an elective replacement indication if at least a predetermined amount of time elapses after receipt of the first sample and before receipt of a second sample of the signal having a second predetermined relationship to a second threshold.

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.

13. A system, comprising:
-
a power source configured to be implantable within a patient; measurement logic configured to obtain samples of a signal indicative of a characteristic of the power source; and a control circuit 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 amount of time elapses following receipt of the first sample and before receipt of a second sample of the signal having a second predetermined relationship to a second threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

30. A non-transitory storage medium storing instructions to cause a control circuit to:
-
receive samples of a signal indicative of a characteristic of the power source; determine when a first sample of the received samples has a first predetermined relationship to a first threshold; and issue an elective replacement indication if a predetermined period of time elapses after receipt of the first sample and before receipt of a second sample of the signal having a second predetermined relationship to a second threshold.
