Abstract

An implantable cardiac function management device including a programmable controller can be used to include a user-specifiable therapy control parameter set. The therapy control parameter set may then be configured to include at least one therapy control parameter that is user-configurable to automatically switch from a first parameter value to a second parameter value at a time that occurs between separate user programming sessions of the device. Various attributes of physiological measures may allow for refinement of the parameter sets to adapt to changed conditions of the subject. Methods of use are also presented.

Claims

1. An apparatus comprising:

an implantable cardiac function management device including a programmable controller, the programmable controller configured to include a user-specifiable therapy control parameter set, wherein the therapy control parameter set is configured to include at least one therapy control parameter that is user-configurable to automatically switch from a first parameter value to a second parameter value at a time that occurs between separate user programming sessions of the device.

2. The apparatus of claim 1, wherein the controller is configured to obtain at least one physiological measure for each combination of parameter values of the therapy control parameter set.

3. The apparatus of claim 2, wherein the at least one physiological measure includes information from a separate and unattached physiological sensor.

4. The apparatus of claim 2, wherein the controller is configured to determine which combination of parameter values contributed to a particular outcome as evidenced by at least one physiological measure.

5. The apparatus of claim 4, wherein the controller is configured to determine which of the first and second parameter value contributed more to the at least one physiological measure.

6. The apparatus of claim 4, wherein the controller is configured to suggest at least one combination of parameter values as a function of past physiological measures.

7. The apparatus of claim 1, wherein the device includes multiple therapy control parameter sets, and wherein the device is configured to sequence through two or more of the therapy control parameter sets.

8. The apparatus of claim 7, wherein at least one therapy control parameter set includes at least one of a user-configurable range and a user-configurable duration.

9. The apparatus of claim 7, wherein the sequence is configured to occur symmetrically from an initial parameter set to a final parameter set.

10. The apparatus of claim 9, wherein the duration is user-specifiable as a period of time.

11. The apparatus of claim 9, wherein the duration is user-specifiable as expiring upon reaching a threshold of detected events.

12. A method comprising:

receiving user input to program a cardiac function management device; and

using the user input to automatically alter, at a time that occurs between separate user-programming sessions, a parameter value of at least one therapy control parameter.

13. The method of claim 12, comprising obtaining at least one physiological measure for each combination of parameter values of the therapy control parameter set.

14. The method of claim 12, comprising determining which of the combination of parameter values contributed to a particular outcome as evidenced by at least one physiological measure.

15. The method of claim 12, comprising using the user input for automatically sequencing through multiple therapy control parameter sets at times occurring between separate user-programming sessions.

16. The method of claim 15, comprising using at least one of a user-specified range and a user-specified duration for performing the sequencing.

17. The method of claim 16, comprising using a user-specified duration that is user-specified as a time.

18. The method of claim 16, comprising using a user-specified duration that is user-specified as a threshold number of detected events.

19. The method of claim 15, wherein the sequencing is configured to occur sequentially from the initial parameter set to the final parameter set.

20. An apparatus comprising:

means for receiving user input to program a cardiac function management device; and

means for using the user input to automatically alter, at a time that occurs between separate user-programming sessions, a parameter value of at least one therapy control parameter.

21. The apparatus of claim 20, comprising means for obtaining at least one physiological measure for each combination of parameter values of the therapy control parameter set.

22. The apparatus of claim 20, comprising means for automatically sequencing, using the user input, through multiple therapy control parameter sets at times occurring between separate user-programming sessions.

23. The apparatus of claim 20, comprising means for using at least one of a user-specified range and a user-specified duration for performing the sequencing.
