INTERVENTION DEVICE WITH ELECTRODES

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 thetarget 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 electrica
