Abstract: A method for stimulating vagal neurons as demonstrated by generation of action potentials on these same neurons, wherein electrical pulse trains are periodically applied to electrodes implanted on the anterior and posterior vagus nerve at an entrance of a diaphragm, wherein each electrical pulse train is formed by a plurality of monophasic pulses having a frequency of at least 13.0 kHz.

Abstract: The present invention relates to a device (2) for reducing weight in an individual, the device (2) comprising: a generator (42, 43) adapted to produce an electrical signal; at least a first set of electrodes (6) comprising two electrodes (10, 12) able to be connected to the generator (42, 43) and being intended to be fixed to a first vagus nerve (18) of the individual at a predefined distance one from another to apply the electrical signal to a portion (19) of the first vagus nerve (18) located between the electrodes (10, 12); characterized in that it comprises a short-circuiting switch (52) being adapted to short-circuit the electrodes (10, 12).
