Devices and methods for stimulating nerves, such as peripheral nerves. Some devices can include small cross-section lead bodies having one or more electrodes in the distal portion, the electrodes having a substantially flat surface and being suitable for placement through a 12 gauge needle or smaller. Some lead electrodes are covered with a hydrophilic coating at least about 0.001 inch thick. The hydrophilic coating may include a steroid and/or a GABBA agonist which can elute or diffuse over time, away from the electrode.
