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 neurostimulation system for use with a neurostimulator to deliver electrical stimulation to one or more electrodes, the neurostimulation 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 a plurality of stimulation parameter sets;
a memory configured for storing a historical log file of stimulation events including stimulation parameter sets for the stimulation events; 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 plurality of 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 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 respective stimulation event.

2. The neurostimulation system of claim 1 , wherein each of the plurality of stimulation parameter sets includes at least one of a pulse amplitude, a pulse wid pulse rate, and an electrode combination.

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

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

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

7. The neurostimulation 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 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 neurostimulation 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 neurostimulation 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 neurostimulation 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 neurostimulation 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 neurostimulation 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 neurostimulation 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 neurostimulation system 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 neurostimulation 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 providing therapy to a patient, comprising:
defining a plurality of stimulation parameter sets;
serially conveying electrical stimulation energy to tissue of the patient in accordance with the plurality of stimulation parameter sets;
storing a historical log file of stimulation events including stimulation parameter sets for the stimulation events; and
logging the plurality of stimulation parameter sets in the historical log file, including automatically logging a new stimulation event in the historical log file when receiving a user input that defines or makes adjustments to the parameter sets; displaying the historical log file including stimulation events; displaying 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.

17. The method of claim 16 , wherein each of the plurality of stimulation parameter sets includes 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. A non-transient machine readable medium containing program instructions for causing a machine to perform the method of:
serially conveying electrical stimulation energy to tissue of the patient in accordance with a plurality of stimulation parameter sets;
storing a historical log file of stimulation events including stimulation parameter sets for the stimulation events; and
logging the plurality of stimulation parameter sets in the historical log file, including:
automatically logging a new stimulation event in
