摘要：
The present invention relates to an intervention device (20) for surgically intervening a target tissue of a human or animal body, comprising a penetrating body (100) arranged to be advanced into the target tissue along an advancing axis (Z+). The penetrating body (100) has an outer surface with a plurality of electrodes (e1, e2, e3, e4,..., eN) insulated from each other. More particularly, the penetrating body comprises a substrate base (5), a number N>；1 of electrically conducting coatings (cce1, cce2, cce3, cce4,..., cceN) and a number M=N-1 electrically insulating coatings (ici1, ici2, ici3,..., iciM). A 1st electrically conducting coating (cce1) at least partially covers the substrate base (5), whereas each mth electrically insulating coating of the M electrically insulating coatings (ici1, ici2, ici3, ici4,..., iciM) partially covers the mth electrically conducting coating of the N electrically conducting coatings (cce1, cce2, cce3, cce4,...) and each nth electrically conducting coating of the N electrically conducting coatings (cce2, cce3, cce4) partially covers the (n-1)th electrically insulating coating (ici1, ici2, ici3). Thus, the outer surface of the penetrating body (100) comprises at least L=N+M sections (e1, i1, e2, i2, e3, i3, e4) alternatingly formed by the N electrically conducting coatings (cce1, cce2, cce3, cce4,..., cceN) and the M electrically insulating coatings (ici1, ici2, ici3,..., iciM). The present invention also relates to a an intervention system comprising a power supply unit and an intervention device (20； 200) as above described, wherein at least one (cce1) of the N electrically conducting coatings (cce1, cce2, cce3, cce4,..., cceN) of the intervention device (20； 200) is connected to the power supply unit such that it forms a cathode and at least another one (cce2, cce3, cce4) of the N electrically conducting coatings is an anode.La présente invention concerne un dispositif d'intervention (20) pour intervenir chirurgicalement un t
