CONFIGURING ELECTRICAL STIMULATION TO TREAT A PATIENT
First Claim
1. A method of configuring electrical stimulation to treat a patient with a stimulation system, the stimulation system including an electrical stimulation generator, an implanted medical lead implanted in the patient and coupled to the electrical stimulation generator, and a programmer with a display screen, the method comprising:
- displaying an image of a tissue on the display screen of the programmer;
determining a position ofthe implanted medical lead with respect to the tissue,an initial stimulation field, andan initial target stimulation area within the initial stimulation field;
displaying the medical lead, the initial stimulation field, and the initial target stimulation area on the image of the tissue, wherein the initial stimulation field has an initial boundary depicted on the display screen and the initial target stimulation area has an initial target boundary depicted on the display screen;
receiving, by the programmer, graphical manipulations of the initial boundary and the initial target boundary to define an altered stimulation field and an altered target stimulation area, wherein the graphical manipulations at least one of move and alter the shape of the initial boundary and the initial target boundary;
determining stimulation parameters to drive the implanted medical lead to generate the altered stimulation field and the altered target stimulation area; and
driving, with the electrical stimulation generator, the implanted medical lead according to the determined stimulation parameters.

Abstract
A stimulation system, such as a spinal cord stimulation (SCS) system, having a programmer with a user interface. The programmer determines a position of an implanted medical lead with respect to a patient'"'"'s spinal column. The programmer overlays the medical lead, an initial stimulation field, and an initial target stimulation area within the initial stimulation field on an image of the spinal column. A user enters, via the user interface, graphical manipulations of displayed boundaries of the initial stimulation field and the initial target stimulation area. The graphical manipulations of the stimulation field and the target stimulation field are independent of each other and they may move and/or alter the shape of the boundaries. The programmer then determines stimulation parameters to drive the implanted medical lead to generate the displayed stimulation field and target stimulation field as manipulated by the user.
