Leadless neurostimulation (NS) device including a device body and electrodes positioned along an active side of the device body. The electrodes form a multi-electrode array that is configured to interface with nervous tissue of a patient and supply electrical pulses to the nervous tissue. The NS device also includes an electronic sub-system that is coupled to the device body. The electronic sub-system includes switching circuitry, a power source, and an inductive coil that is operably coupled to the power source. The inductive coil is configured to receive electrical power through inductive coupling with an external coil. The device body, including the inductive coil coupled thereto, is sized and shaped to be disposed within an epidural space of a patient.
