Patent ID: 7620452

Claim:
A system for managing battery longevity of an implantable medical device (“IMD”) battery, comprising: an IMD comprising a battery and a first communication interface; and an external programming device, comprising: a user interface display; and a second communication interface operable to communicate at least with the first communication interface of the IMD; wherein the external programming device is operable to: receive battery parameters values from the IMD; calculate an elapsed battery longevity value for the IMD battery; calculate a remaining battery longevity value for the IMD battery; calculate a total IMD battery longevity value from the elapsed battery longevity value and the remaining battery longevity value; determine from the total IMD battery longevity value whether the IMD battery longevity is sub-optimal; display IMD parameters that cause sub-optimal IMD battery longevity on the user interface display; and receive commands to adjust the IMD parameters to improve the IMD battery longevity.
