摘要： An implantable neurostimulation electrode array may include a flexible, electrically non-conductive carrier, and a plurality of electrodes supportably interconnected to and spaced along a length of a carrier. In various embodiments, different ones of at least some of the plurality of electrodes may comprise corresponding contact surfaces having different areas. The different surface areas may be achieved by defining a different area per unit length of the carrier and/or by defining a different total length (e.g. as measured along a length of the carrier). In some embodiments, insulator portions having different corresponding lengths may be disposed between different adjacent ones of the electrodes. The insulated portions may be integrally defined with the carrier. Electrical connection lines may be embedded within the carrier. In a manufacturing method, a plurality of electrodes may be supportably interconnected to a first side of a sacrificial substrate and a carrier may be interconnected to the electrodes. In turn, at least a portion of the substrate may be removed from the electrodes to yield at least a partially completed electrode array. The substrate may be configured into a predetermined configuration wherein the carrier material may be formed within an internal volume thereof to define at least a portion of the configuration of the carrier of the electrode array.
