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. An external control device for use with a neurostimulator coupled to one or more electrodes implanted within tissue, comprising:
a user interface including a display screen and one or more stimulation parameter controls configured for being actuated by a user to define stimulation parameter sets;
memory configured for storing a historical log file of stimulation events including stimulation parameter sets for the stimulation events, the historical log file including stimulation parameter values associated with respective stimulation parameters sets, the display screen configured for displaying the historical log file of stimulation events including the stimulation parameter values for the stimulation parameter sets; and
a controller configured for, in response to an input from the user, instructing the neurostimulator to serially convey electrical stimulation energy to the one or more electrodes in accordance with the stimulation parameter sets, wherein the controller is configured to log a new stimulation event in the historical log file when the user input defines or makes adjustments to the parameter sets, including logging stimulation parameter values for the new stimulation event in the historical log file,
wherein the controller is configured for togging temporal stamps in the historical log file respectively indicating when the plurality of stimulation parameter sets were defined and for displaying on the display screen the temporal stamps with their respective stimulation parameter set in the displayed historical log file of stimulation events,
wherein the device is configured to display on the display screen serial identifiers respectively associated with the stimulation parameter sets in the historical log file, the serial identifiers being different than the temporal stamps and providing a serial representation of the order in which the stimulation parameter sets were defined, and
wherein the device is configured to display information icons associated with respective stimulation events in the displayed historical log file of stimulation events, wherein each information icon is selectable to display the stimulation parameter values associated with the respective stimulation event.

2. The external control device of claim 1 , wherein each information icon is selectable to display values selected from a group of values consisting of: a pulse amplitude value, a pulse width value, and a pulse rate value associated with the respective stimulation events.

3. The external control device of claim 1 , wherein the one or more electrodes comprises a plurality of electrodes, each of the plurality of stimulation parameter sets includes fractionalized electrical current values respectively for the electrodes, and each information icon is selectable to display a graphical representation of the plurality of electrodes, and display the fractionalized electrical current values with the graphical representation of the plurality of electrodes.

4. The external control device of claim 1 , wherein the temporal stamps are absolute.

5. The external control device of claim 1 , wherein the temporal stamps are relative to a start of a therapeutic procedure.

6. The external control device of claim 1 , wherein each of the temporal stamps is at least one of a time stamp and a date stamp.

7. The external control device 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 plurality of stimulation parameter sets in the historical log file or prevent the controller from logging the plurality of stimulation parameter sets in the historical log file.

8. The external control device of claim 1 , wherein each information icon is selectable to display a dialog box to access additional information including comments respectively associated with the respective logged stimulation parameter set, the dial box includes stimulation parameter values respectively associated with respective stimulation events.

9. The external control device of claim 8 , wherein each information icon is selectable to allow the user to add additional information associated with the respective logged stimulation parameter set.

10. The external control device of claim 1 , wherein the user interface is further 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 external control device 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 external control device 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 external control device 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 external control device of claim 10 , wherein the user interface includes a directional control device, the actuation of which defines a plurality of predicted stimulation regions relative to the at least one electrode respectively corresponding to the plurality of 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 external control device of claim 1 , further comprising output circuitry configured for transmitting instructions to the neurostimulator.

16. An external control device for use with a neurostimulator coupled to a plurality of electrodes implanted within tissue, comprising:
a user interface including a display screen and one or more stimulation parameter controls configured for being actuated by a user to define stimulation parameter sets for testing during one or more stimulation programming sessions;
memory configured for storing a historical log of stimulation events including stimulation parameter sets for the stimulation events, the historical log including stimulation parameter values associated with respective stimulation parameter sets, the display screen configured for displaying the historical log of stimulation events including the stimulation parameter values for the stimulation parameter sets; and
a controller configured for, in response to an input from the user to test a newly defined or adjusted parameter set to be tested, logging the newly defined or adjusted parameter set as a new stimulation event in the historical log along with a temporal stamp indicating when the parameter set was defined or adjusted,
wherein the device is configured to display with the historical log on the display screen:
the stimulation parameter sets tested during one or more
