Abstract
The present invention relates to an intervention device () for surgically intervening a target tissue of a human or animal body, comprising a penetrating body () arranged to be advanced into the target tissue along an advancing axis (Z+). The penetrating body () 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 (), a number N>1 of electrically conducting coatings (cc, cc, cc, cc, . . . , cc) and a number M=N−1 electrically insulating coatings (ic, ic, ic, . . . , ic). A 1electrically conducting coating (cc) at least partially covers the substrate base (), whereas each melectrically insulating coating of the M electrically insulating coatings ic, ic, ic, ic, . . . , ic) partially covers the melectrically conducting coating of the N electrically conducting coatings (cc, cc, cc, cc, . . . ) and each nelectrically conducting coating of the N electrically conducting coatings (cc, cc, cc) partially covers the (n−1)electrically insulating coating (ic, ic, ic). Thus, the outer surface of the penetrating body () comprises at least L=N+M sections (e1, i1, e2, i2, e3, i3, e4) alternatingly formed by the N electrically conducting coatings (cc, cc, cc, cc, . . . , cc) and the M electrically insulating coatings (ic, ic, ic, . . . , ic). The present invention also relates to a an intervention system comprising a power supply unit and an intervention device () as above described, wherein at least one (cc) of the N electrically conducting coatings (cc, cc, cc, cc, . . . , cc) of the intervention device () is connected to the power supply unit such that it forms a cathode and at least another one (cc, cc, cc) of the N electrically conducting coatings is an anode.
