Abstract

In one embodiment, an external programming device is operable to determine and graphically display power consumption of an implantable medical device (“IMD”). In accordance with this particular embodiment, the external programming device includes a graphical user interface display and a communication interface operable to receive information from an IMD. In this embodiment, the external programming device is operable to receive IMD parameter settings and/or battery parameter values from the IMD, calculate a power consumption rate for the IMD, and then display the power consumption on the graphical user interface display using a graphical visual indicator.

Claims

1. An external programming device operable to determine and graphically display power consumption of an implantable medical device (“

IMD”

), comprising;

a graphical user interface display; and

a communication interface operable to receive information from an IMD;

wherein the external programming device is further operable to;

receive IMD parameter setting values from the IMD;

calculate a power consumption of the IMD; and

display the power consumption on the graphical user interface display using a graphical visual indicator.

2. The device as recited in claim 1, wherein the IMD is a cardiac rhythm management device selected from the group consisting of a pacemaker, an implantable cardioverter defibrillator (“

ICD”

), a pacer/defibrillator, and a cardiac resynchronization (“

CRT”

) device.

3. The device as recited in claim 1, wherein the external programming device is further operable to use the power consumption to determine whether the IMD longevity is sub-optimal.

4. The device as recited in claim 1, wherein the external programming device calculates a power consumption for the IMD by calculating a power consumption based on one or more parameters selected from the group consisting of lead impedance, pace or sense rate, programmed pulse width, programmed pulse amplitude and sensor load.

5. The device as recited in claim 1, wherein the external programming device is further operable to:

determine whether the power consumption is sub-optimal; and

identify one or more parameters contributing to the sub-optimal power consumption.

6. The device as recited in claim 5, wherein the external programming device is further operable to:

receive commands to adjust at least one of one or more parameters contributing to the sub-optimal power consumption;

adjust the at least one parameter;

calculate an adjusted power consumption for the IMD using the at least one adjusted parameter; and

display the adjusted power consumption on the graphical visual indicator.

7. The device as recited in claim 1, wherein the graphical visual indicator is selected from the group consisting of a level indicator, a multi-colored display, a gray-scale display, a multi-size indicator, a radial indicator and a pie indicator.

8. The device as recited in claim 7, wherein the graphical visual indicator comprises a three-color display.

9. The device as recited in claim 8, wherein the first color on the display indicates a power consumption rate, the second color on the display indicates an elevated power consumption rate, and the third color on the display indicates a high power consumption rate.

10. The device as recited in claim 7, wherein the graphical visual indicator comprises a multi-level display.

11. The device as recited in claim 10, wherein the first level on the display indicates a power consumption rate, the second level on the display indicates an elevated power consumption rate, and the third level on the display indicates a high power consumption rate.

12. The device as recited in claim 10, wherein each level on the display comprises one or more level indicators within each level.

13. The device as recited in claim 8, wherein each level indicator is indicative of a power consumption rate.

14. A system for determining and graphically displaying power consumption of an implantable medical device (“

IMD”

), comprising;

an IMD comprising a battery and a first communication interface; and

an external programming device comprising;

a graphical 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 IMD parameter setting values from the IMD;

calculate a power consumption rate; and

display the power consumption on the graphical user interface display using a graphical visual indicator.

15. A system for determining and graphically displaying power consumption of an implantable medical device (“

IMD”

), comprising;

an IMD comprising a battery and a first communication interface, the IMD being operable to calculate a power consumption for the IMD; and

an external programming device, comprising

a graphical 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 the power consumption from the IMD; and

display the power consumption on the graphical user interface display using a graphical visual indicator.

16. The system as recited in claim 15, wherein the IMD is a cardiac rhythm management device selected from the group consisting of a pacemaker, an implantable cardioverter defibrillator (“

ICD”

), a pacer/defibrillator, and a cardiac resynchronization (“

CRT”

) device.

17. The system as recited in claim 15, wherein the external programming device is further operable to use the power consumption to determine whether the IMD longevity is sub-optimal.

18. The system as recited in claim 15, wherein the external programming device is operable to calculate a power consumption for the IMD by calculating a power consumption based on one or more parameters selected from the group consisting of lead impedance, pace or sense rate, programmed pulse width, programmed pulse amplitude and sensor load.

19. The system as recited in claim 15, wherein the external programming device is further operable to:

determine whether the power consumption is sub-optimal; and

identify one or more parameters contributing to the sub-optimal power consumption.

receive commands to adjust at least one of one or more parameters contributing to the sub-optimal power consumption;

adjust the at least one parameter;

calculate an adjusted power consumption for the IMD using the at least one adjusted parameter; and

display the adjusted power consumption on the graphical visual indicator.
