A Medical Device Application (MDA) is disclosed for an external device (e.g., a cell phone) that can communicate with an Implantable Medical Device (IMD). The MDA receives data logged in the IMD, processes that data in manners reviewable by an IMD patient, and that can control the IMD based on such processed data. The MDA can use the logged data to adjust IMD therapy based on patient activity or posture, and allows a patient to learn optimal therapy settings for particular activities. The MDA can also use the logged data to allow a patient to review details about IMD battery performance, whether such battery is primary or rechargeable, and to control stimulation parameters based on that performance. The MDA also allows a patient to enter medicine dose information, to review the relationship between medicinal therapy and IMD therapy, and to adjust IMD therapy based on the dosing information.

1. A non-transitory machine-readable medium storing instructions for a medical device application that when executed on an external device will: receive data logged in an implantable medical device (IMD), wherein the logged data comprises at least one therapy parameter previously provided by the IMD
1. A non-transitory machine-readable medium storing instructions for a medical device application that when executed on an external device will: receive data logged in an implantable medical device (IMD), wherein the logged data comprises at least one therapy parameter previously provided by the IMD to the patient and a voltage of a primary battery in the IMD;assess the received data to estimate a first end of life of the primary battery;provide a Graphical User Interface (GUI) on the external device, wherein the GUI displays the estimated first end of life of the primary battery;provide an option on the GUI to allow input to set a second end of life for the primary battery;automatically adjust at least one therapy parameter to extend an end of life of the primary battery from the first end of life to the second end of life; andtransmit the adjusted at least one therapy parameter from the external device to the IMD to control the therapy the IMD provides to the patient. 2. The medium of claim 1, wherein the GUI further allows input to adjust at least one therapy parameter to control the therapy the IMD provides to the patient. 3. The medium of claim 1, wherein assessing the received data to estimate a first end of life of the primary battery comprises determining a correlation between the voltage of the primary battery and time. 4. The medium of claim 1, wherein assessing the received data to estimate a first end of life of the primary battery comprises determining a time at which a remaining charge in the primary battery will be exhausted in light of the at least one therapy parameter received from the IMD. 5. The medium of claim 1, wherein the medical device application when executed on the external device will further: determine a scalar between a time to the first end of life and a time to the second end of life; andadjust at least one therapy parameter in accordance with the scalar. 6. The medium of claim 1, wherein the adjusted at least one therapy parameter comprises an intensity of a therapeutic current. 7. The medium of claim 1, wherein assessing the received data to estimate a first end of life of the primary battery comprises extrapolating a relationship between the voltage of the battery and time to estimate when the voltage of the battery will be equal to a minimum operational voltage required by the IMD. 8. The medium of claim 1, wherein assessing the received data to estimate a first end of life of the primary battery comprises calculating a total charge expended by the battery based, at least in part, on the received at least one therapy parameter. 9. The medium of claim 8, wherein calculating the total charge expended by the battery comprises: determining a per-pulse charge delivered to the patient within each of one or more time periods based on the received at least one therapy parameter;determining a number of pulses within each of the one or more time periods based on the received at least one therapy parameter;determining a charge expenditure within each of the one or more time periods based on the per-pulse charge and the number of pulses within each of the one or more time periods; andcalculating the total charge expended by summing the charge expenditures for each of the one or more time periods. 10. The medium of claim 8, wherein assessing the received data to estimate a first end of life of the primary battery further comprises extrapolating a relationship between total charge expended and time to estimate when the total charge expended will equal the charge capacity of the battery. 11. The medium of claim 1, wherein the external device is a mobile, multipurpose consumer electronic device. 12. An external device, comprising: a memory; anda processor having access to the memory and configured to execute program code stored in the memory to cause the processor to: receive data logged in a medical device that is implanted in a patient, wherein the logged data comprises at least one therapy parameter previously provided by the implanted medical device (IMD) to the patient and a voltage of a primary battery in the IMD;assess the received data to estimate a first end of life of the primary battery;provide a Graphical User Interface (GUI) on the external device, wherein the GUI displays the estimated first end of life of the primary battery;provide an option on the GUI to allow input to set a second end of life for the primary battery;automatically adjust at least one therapy parameter to extend an end of life of the primary battery from the first end of life to the second end of life; andtransmit the adjusted at least one therapy parameter from the external device to the IMD to control the therapy the IMD provides to the patient. 13. The external device of claim 12, wherein the program code to cause the processor to assess the received data to estimate a first end of life of the primary battery comprises program code to cause the processor to determine a correlation between the voltage of the primary battery and time. 14. The external device of claim 12, wherein the program code to cause the processor to assess the received data to estimate a first end of life of the primary battery comprises program code to cause the processor to determine a time at which a remaining charge in the primary battery will be exhausted in light of the at least one therapy parameter received from the IMD. 15. The external device of claim 12, wherein the adjusted at least one therapy parameter comprises an intensity of a therapeutic current. 16. The external device of claim 12, wherein the adjusted at least one therapy parameter comprises a frequency and pulse width of therapeutic pulses. 17. The external device of claim 12, wherein the program code to cause the processor to assess the received data to estimate a first end of life of the primary battery comprises program code to cause the processor to extrapolate a relationship between the voltage of the battery and time to estimate when the voltage of the battery will be equal to a minimum operational voltage required by the IMD. 18. The external device of claim 12, wherein the program code to cause the processor to assess the received data to estimate a first end of life of the primary battery comprises program code to cause the processor to: calculate a total charge expended by the battery based, at least in part, on the received at least one therapy parameter; andextrapolate a relationship between total charge expended and time to estimate when the total charge expended will equal the charge capacity of the battery.
