Abstract

A device that programs a medical device includes a display and a user input device. The device displays a graphical representation of a plurality of electrodes on a medical lead implanted in the patient, and displays an active electrode template at a first position relative to the graphical representation of the electrodes. A processor of the device receives input dragging the active electrode template. In response to the input dragging the active electrode template, the processor adjusts at least one parameter of electrical stimulation delivered to the patient via the lead based on the position of the active electrode template relative to the graphical representation of the electrodes on the medical lead.

Claims

1. A method for programming a single channel pulse generator of an implantable medical device, the method comprising:

displaying a graphical representation of a plurality of electrodes implanted within a patient on at least one medical lead;

displaying an active electrode template at a first position relative to the graphical representation of the electrodes, the active electrode template including one or more anodes and one or more cathodes and defining a spatial relationship of the one or more anodes and one or more cathodes;

receiving input from a user moving the active electrode template to a second position relative to the graphical representation of the electrodes; and

in response to the input moving the active electrode template, adjusting at least one parameter of electrical stimulation delivered from the single channel pulse generator to the patient via at least a subset of the implanted electrodes based on the second position of the active electrode template relative to the graphical representation of the electrodes on the stimulation lead,

wherein at least one of the one or more anodes and one or more cathodes of the active electrode template is displaced from the electrodes of the graphical representation when the active electrode template is located at the second position.

2. The method of claim 1, wherein each of the one or more anodes and one or more cathodes of the active electrode template is displaced from the electrodes of the graphical representation when the active electrode template is located at the second position.

3. The method of claim 1, wherein adjusting the parameter of electrical stimulation delivered by the single channel pulse generator comprises adjusting at least one of which of the implanted electrodes are active or polarities of active ones of the implanted electrodes based on the second position of the active electrode template relative to the graphical representation of the electrodes.

4. The method of claim 3, wherein a number of active implanted electrodes subsequent to the adjustment based on the second position of the active electrode template is different than a number of electrodes in the active electrode template.

5. The method of claim 3, wherein the polarities of active implanted electrodes subsequent to the adjustment based on the second position of the active electrode template are different than polarities of the active electrode template.

6. The method of claim 3, wherein a spatial relationship of active implanted electrodes subsequent to the adjustment based on the second position of the active electrode template is different than the spatial relationship of electrodes in the active electrode template.

7. The method of claim 3, wherein each active implanted electrode is fully on, and each inactive implanted electrode is fully off.

8. The method of claim 1, wherein adjusting the parameter of electrical stimulation delivered by the single channel pulse generator comprises adjusting the potentials of implanted electrodes based on the second position of the active electrode template relative to the graphical representation of the electrodes.

9. The method of claim 1, wherein receiving input from a user positioning the active electrode template at a second position comprises receiving input rotating the active electrode template about an axis point.

10. A system for programming a single channel pulse generator of an implantable medical device, the system for programming comprising:

a display that displays a graphical representation of a plurality of electrodes implanted within a patient on, and coupled to the pulse generator by, at least one medical lead, and displays an active electrode template at a first position relative to the graphical representation of the electrodes, the active electrode template including one or more anodes and at one or more cathodes and defining a spatial relationship of the one or more anodes and one or more cathodes;

a user input device; and

a processor that;

receives input from a user moving the active electrode template to a second position relative to the graphical representation of the electrodes via the user input device, and

in response to the input moving the active electrode template, adjusts at least one parameter of electrical stimulation delivered from the single channel pulse generator to the patient via at least a subset of the implanted electrodes based on the second position of the active electrode template relative to the graphical representation of the electrodes,

wherein at least one of the one or more anodes and one or more cathodes of the active electrode template is displaced from the electrodes of the graphical representation when the active electrode template is located at the second position.

11. The system of claim 10, wherein each of the one or more anodes and one or more cathodes of the active electrode template is displaced from the electrodes of the graphical representation when the active electrode template is located at the second position.

12. The system of claim 10, wherein the processor adjusts at least one of which of the implanted electrodes are active, or polarities of active ones of the implanted electrodes, based on the second position of the active electrode template relative to the graphical representation of the electrodes.

13. The system of claim 12, wherein a number of active implanted electrodes subsequent to the adjustment based on the second position of the active electrode template is different than a number of electrodes in the active electrode template.
