Abstract: The invention relates to a device (10) for supporting a treatment using pulsed electric fields in order to heal wounds and/or for the inactivation of microorganisms. The device comprises an electric energy storage device (16), a pulse generator (17) for providing electric excitation pulses, a transformer (26) for providing high-frequency electric pulses (200) on an output side (28), a first connection of the input side (27) of the transformer (26) being connected to the pulse generator (17), and a treatment instrument (100) which comprises a closed body (102) made of an electrically insulating material and an electrode (110) arranged in the interior of the body (102). A gas or a gas mixture is received in the interior of the body (102), and the treatment instrument (100) is designed to discharge gas in the event of an electric excitation. A first end (103) of the treatment instrument (100) is designed to couple to a first connection of the output side (28) of the transformer (26).
