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.
