    an insulation layer of an electrically insulating material, sheathing the cable;

    a plurality of exposed areas formed in the insulation layer so as to form corresponding electrodes of the microlead;

    an interstitial space defined between the microcables and an internal wall of the insulation layer between the plurality of exposed areas; and
