Abstract

An external control device, a neurostimulation system, and a method for providing therapy to a patient are provided. A plurality of stimulation parameter sets are defined, electrical stimulation energy is serially conveyed to tissue of the patient in accordance with the plurality of stimulation parameter sets, a historical log file is stored, and the plurality of stimulation parameter sets are logged in the historical log file.

First claim

What is claimed is:

1. A system for use in evaluating stimulation parameter sets used by a neurostimulator to deliver neurostimulation, the system comprising:
a user interface including a display screen and one or more stimulation parameter controls configured for being actuated by a user to define or adjust any of the stimulation parameter sets for the neurostimulator to use to deliver the neurostimulation;
a memory; and
a controller configured to, when defining or adjusting one of the stimulation parameter sets, log a stimulation event in a historical log file stored in the memory including log stimulation parameter values for the stimulation parameter set corresponding to the stimulation event in the historical log file, wherein the historical log file stored in the memory is configured to include a plurality of stimulation events and corresponding parameter sets including stimulation parameter values associated with the corresponding parameter sets, wherein the system is configured to display information icons on the display screen, the information icons being associated with respective stimulation events in the historical log file of stimulation events, each information icon being selectable to display the stimulation parameter values associated with the stimulation parameter set corresponding to the respective stimulation event.

2. The system of claim 1 , wherein the stimulation parameter sets include at least one of a pulse amplitude, a pulse width, a pulse rate, and an electrode combination.

3. The system of claim 1 , wherein the stimulation parameter sets include fractionalized electrical current values respectively for a plurality of electrodes, and the user interface includes a display screen configured for displaying a graphical representation of the plurality of electrodes, and for displaying the fractionalized electrical current values in association with the graphical representation of the plurality of electrodes.

4. The system of claim 1 , wherein the controller is configured for logging temporal stamps in the historical log file respectively indicating when the stimulation parameter sets were defined.

5. The system of claim 4 , wherein the temporal stamps are absolute or are relative to a start of a therapeutic procedure.

6. The system of claim 4 , wherein each of the temporal stamps includes at least one of a time stamp or a date stamp.

7. The system of claim 1 , wherein the user interface includes an enable/disable control configured for being actuated by the user to selectively allow the controller to log the stimulation parameter set in the historical log file or prevent the controller from logging the stimulation parameter set in the historical log file.

8. The system of claim 1 , wherein the user interface includes a display screen configured for displaying the historical log file, wherein the displayed historical log file includes serial numbers respectively associated with the logged stimulation parameter sets, the serial numbers corresponding to the order in which the stimulation parameter sets were defined.

9. The system of claim 1 , wherein each information icon is selectable to allow the user to add additional information associated with the respective logged stimulation parameter set.

10. The system of claim 1 , wherein the user interface is configured for allowing the user to select one of the logged stimulation parameter sets, and the controller is further configured for, in response to the selected logged stimulation parameter set, automatically resetting the one or more stimulation parameter controls to define the selected logged stimulation parameter set.

11. The system of claim 10 , wherein the user interface includes a display screen configured for displaying the historical log file as a list, and the user interface is configured for allowing the user to select the logged stimulation parameter set from the displayed list with a pointing device.

12. The system of claim 10 , wherein the user interface includes an undo control, the actuation of which selects the logged stimulation parameter set immediately defined prior to a stimulation parameter set currently defined by the one or more stimulation parameter controls.

13. The system of claim 10 , wherein the user interface includes a redo control, the actuation of which selects the logged stimulation parameter set immediately defined subsequent to a stimulation parameter set currently defined by the one or more stimulation parameter controls.

14. The system of claim 10 , wherein the user interface includes a directional control device, the actuation of which defines predicted stimulation regions relative to the at least one electrode respectively corresponding to stimulation parameter sets, the user interface further includes a display screen configured for displaying the historical log file as a trace that spatially connects points respectively corresponding to the predicted stimulation regions, and the user interface is configured for allowing the user to select the logged stimulation parameter set from the displayed trace with a pointing device.

15. The system of claim 10 , further comprising an external control device including a housing containing the user interface, the memory, and the controller.

16. A method for use in evaluating stimulation parameter sets used by a neurostimulator to deliver neurostimulation, the method comprising:
programming the stimulation parameter set for use by the neurostimulator to deliver neurostimulation;
logging the stimulation parameter set in a historical log file, including automatically logging a stimulation event in the historical log file when the stimulation parameter set is programmed, wherein the historical log file is configured to store stimulation parameter sets for stimulation events;
displaying the stimulation events stored in the historical log file; and
displaying information icons associated with the displayed stimulation events respectively, wherein each information icon is selectable to display stimulation parameter values associated with the parameter set for the respective stimulation event.

17. The method of claim 16 , wherein the stimulation parameter sets include fractionalized electrical current values respectively for a plurality of electrodes, the method further comprising:
displaying a graphical representation of the plurality of electrodes; and
displaying the fractionalized electrical current values in association with the graphical representation of the plurality of electrodes.

18. The method of claim 16 , wherein the program instructions further cause the machine to allow the user to select each information icon to add additional information associated with the respective logged stimulation parameter set.

19. A non-transitory machine-readable medium including instructions, which when executed by a machine, cause the machine to implement a process for use in evaluating stimulation parameter sets used by a neurostimulator to deliver neurostimulation, including:
log a stimulation event in a historical log file when each one of the parameter sets is defined or adjusted by a user;
instruct a user interface to display the stimulation events logged in the historical log file; and
instruct the user interface to display information icons associated with the displayed stimulation events respectively, wherein each information icon is selectable to display stimulation parameter values associated with the parameter set for the respective stimulation event.
