Abstract

The disclosure describes a method and system that allows a user to configure electrical stimulation therapy by defining a three-dimensional (3D) stimulation field. After a stimulation lead is implanted in a patient, a clinician manipulates the 3D stimulation field in a 3D environment to encompass desired anatomical regions of the patient. In this manner, the clinician determines which anatomical regions to stimulate, and the system generates the necessary stimulation parameters. In some cases, a lead icon representing the implanted lead is displayed to show the clinician where the lead is relative to the 3D anatomical regions of the patient.

Claims

presenting, by a user interface, a graphical representation of an anatomical region of a patient;

presenting, by the user interface, a graphical representation of an electrical stimulation lead with respect to the graphical representation of the anatomical region;

presenting, by the user interface, a graphical representation of a stimulation field with respect to the graphical representation of the electrical stimulation lead; and

presenting, by the user interface and simultaneously with the graphical presentations of the anatomical region, the electrical stimulation lead, and the stimulation field, an adjustment mechanism configured to receive user input that adjusts a value of a parameter that at least partially defines electrical stimulation deliverable by the electrical stimulation lead to the patient.

2. The method of claim 1, wherein:

the graphical representation of the anatomical region is a three-dimensional (3D) anatomical region in a 3D environment, and

the graphical representation of the stimulation field is a 3D stimulation field within the 3D environment.

3. The method of claim 1, wherein the graphical representation of the electrical stimulation lead comprises a graphical representation of at least one electrode of the electrical stimulation lead.

4. The method of claim 3, wherein the at least one electrode comprises a complex electrode array geometry comprising a plurality of non-contiguous electrode segments located at different angular positions about a circumference of the electrical stimulation lead.

5. The method of claim 1, wherein the parameter is a voltage, and wherein the value is an amplitude of the voltage.

6. The method of claim 1, wherein the adjustment mechanism comprises one of a slider or a knob.

7. The method of claim 1, wherein the parameter is one parameter of a plurality of parameters that define the electrical stimulation.

8. The method of claim 1, wherein the value of the parameter is a first value of the parameter, and wherein the method further comprises:

receiving user input via the adjustment mechanism that adjusts the first value of the parameter to a second value of the parameter; and

responsive to receiving the user input that adjusts the first value of the parameter to the second value of the parameter, modifying, based on the second value of the parameter, at least one of a size, a shape, or a location of the graphical representation of the stimulation field.

9. The method of claim 1, further comprising:

receiving stimulation field input from a user that defines the stimulation field with respect to the graphical representation of the electrical stimulation lead; and

generating, by a processor and based on the stimulation field input, the graphical representation of the stimulation field.

10. The method of claim 1, wherein the anatomical region comprises at least one of a cerebrum, a cerebellum, and a brain stem.
