Abstract: A device which includes a generator of electric current pulses and a neurostimulation probe with M sectoral electrodes forming stimulation poles for passing a current between at least one anode and at least one cathode in a predetermined stimulation configuration. The generator includes N current sources and N current sinks, the N sources and the N sinks being defined independently of the M electrodes. A first distribution circuit can indiscriminately and dynamically switch any of the N sources to any of the M electrodes, and a second distribution circuit can indiscriminately and dynamically switch any of the N sinks to any of the M electrodes. The device can thus define a plurality of commutation combinations between sources and/or sinks, providing a single average current in the organ to be stimulated for different respective predetermined pole configurations.
