Battery longevity monitoring
First Claim
1. A non-transitory computer-readable storage medium comprising instructions for causing a programmable processor to:
- receive a plurality of parameters from a data mart, the plurality of parameters including at least some parameters having been provided by a medical device implanted in a patient to the data mart on an actual transmission date, the parameters including an actual battery voltage value as of the actual transmission date;
generate a curve indicating how a battery of the medical device implanted in the patient will deplete over time by at least applying a battery longevity model to the plurality of parameters, the curve including a model battery voltage versus a model medical device implant duration;
determine a model transmission date by finding the actual battery voltage value on the curve;
compare the model transmission date with the actual transmission date;
adjust the curve until the model transmission date accords with the actual transmission date to a threshold degree; and
determine a model replacement date by finding a replacement battery voltage value on the curve.

Abstract
Systems and methods are provided that estimate when to replace a medical device that is implanted in a patient due to battery depletion. These systems and methods significantly reduce the need for service calls made to medical device manufacturers that relate to battery longevity. In some examples, these systems and methods estimate a battery end of life based, at least in part, on an actual battery voltage received on an actual transmission date and a model transmission date determined based on the actual battery voltage. The estimated battery end of life is further based on a comparison of the model transmission date with the actual transmission date.
