Embodiments of the implantable device include an electrode lead and a pelvic treatment apparatus. One embodiment of the electrode lead (104) comprises a lead body (110), an electrode (111) attached to a distal end (114) of the lead body and a tissue anchor (120). The electrode comprises a plurality of stimulation elements (112) formed of an electrically conductive material, and at least one insulative element (116) formed of an electrically non-conductive material. The stimulation elements and the at least one insulative element are joined together to form a stacked column (140) of alternating stimulation and insulative elements. The electrode lead also comprises a plurality of electrically conductive wires (118) each extending through the lead body and coupled to one of the stimulation elements. The tissue anchor is configured to facilitate anchoring the electrode to tissue (240) of the patient.
