Electrotherapeutic systems, devices, and methods are described. In one embodiment, a portion of a hepatic branch of a vagus nerve in a liver is stimulated with a lead implanted in the liver. In another embodiment, a stimulation member is delivered to a location in the gastrointestinal tract and implanted in a target area endoscopically and under ultrasound visualization. In another embodiment, a stimulation device is magnetically coupled to a stimulation member in order to electrically couple stimulation generation circuitry with a lead implanted in a target area.
