A microlead includes a conductive cable formed by a strand of microcables, each microcable being formed of a strand of individual metallic wires. The microlead also includes an insulation layer sheathing the cable. The microlead further includes at least one exposed area formed in the insulation layer so as to form a corresponding electrode of the microlead. The microlead further includes a pharmacologically active agent (e.g., an anti-inflammatory agent) configured to gradually be released into the environment of the microlead after implantation of the microlead. The pharmacologically active agent may be a soluble material. An interstitial space, delimited by the inner wall of the insulation layer and existing in the remainder between the wires of each microcable, is filled with the pharmacologically active agent.
