NEUROSTIMULATION ELECTRODE ARRAY AND METHOD OF MANUFACTURE

Title:

NEUROSTIMULATION ELECTRODE ARRAY AND METHOD OF MANUFACTURE

Document Type and Number:

WIPO Patent Application WO/2010/121240

Kind Code:

A3

Abstract:

An implantable neurostimulation electrode array may include a flexible, electrically nonconductive carrier, and a plurality of electrodes supportably interconnected to and spaced along a length of a carrier In vaπous 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). 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.
