Abstract:
1. A system for treating pain comprising: at least one implantable device that is configured to generate a plurality of electrical signals; a spinal lead having a first end connected to the implantable device and a second end connected to a first set of electrodes, the first set of electrodes in communication with the implantable device and implantable within an epidural space proximate to a spinal cord; a first subcutaneous lead having a third end connected to the implantable device and a fourth end connected to a second set of electrodes, the second set of electrodes in communication with the implantable device and implantable at least partially within subcutaneous tissue and positioned on a first side of the spinal cord; a second subcutaneous lead having a fifth end connected to the implantable device and a sixth end connected to a third set of electrodes, the third set of electrodes in communication with the implantable device and implantable at least partially within subcutaneous tissue and positioned on a second side of the spinal cord; and wherein the second and third sets of electrodes are spaced apart from each other on opposite sides of a spinal cord axis and the first set of electrodes are spaced along the spinal cord axis longitudinally apart from the second and third sets of electrodes to form a triangular shape, the implantable device programmed with a stimulation program that causes the electrical signals to be transmitted between the second and third sets of electrodes in the subcutaneous tissue and the first set of electrodes in the epidural space providing a field of electrical stimulation about the triangular shape.
