Devices and systems for electrical stimulation and methods of use

The present disclosure provides devices, systems, and methods for spinal cord stimulation. In some exemplary embodiments, a lead is provided. In one exemplary embodiment, the lead includes a paddle and an electrode array distributed in the paddle. The electrode array includes a first column of electrodes and a second column of electrodes. The first column of electrodes and the second column of electrodes are symmetric about the midline of the paddle. The first column of electrodes includes a first electrode, a second electrode, and a third electrode. The second column of electrodes includes a fourth electrode corresponding to the first electrode, a fifth electrode corresponding to the second electrode, and a sixth electrode corresponding to the third electrode. A vertical inter-electrode distance between the first electrode and the second electrode is larger than that between the second electrode and the third electrode.
