METHOD AND APPARATUS FOR DETERMINING LONGEVITY

摘要

A method and apparatus for determining estimated remaining longevity for an implantable stimulator. The device employs pre-calculated numbers of days for various combinations conditions of device usage parameters to determine remaining device longevity based upon identified actual conditions of device usage and employs the determined longevity to change longevity indicator states in the device. While between longevity state changes, the device the identified conditions of device usage and adjusts the determined longevity if the conditions of use change significantly. The indicator states may correspond to one or more of Recommended Replacement Time (RRT), Elective Replacement Indicator (ERI) or End of Service (EOS).

1. A method of determining estimated remaining longevity for an implantable stimulator, comprising:
employing pre-calculated numbers of days for various combinations of device usage parameters to determine remaining device longevity based upon identified actual conditions of device usage; employing the determined longevity to change longevity indicator states in the device; and while between longevity state changes, monitoring to verify that the device continues to operate according to the identified conditions of device usage and adjusting the determined longevity if conditions of use change significantly.
