US 11,951,301 B2 · Nerve cuff electrodes fabricated using over-molded LCP substrates

Abstract

An electrode lead may comprise a flexible circuit that includes a planar dielectric substrate including an elongated lead substrate portion having opposing ends, an electrode carrying substrate portion disposed on one end of the lead substrate portion, and a connector substrate portion disposed on the other end of the lead substrate portion, wherein the lead substrate portion is pre-shaped into a three-dimensional structure. The flexible circuit may further include an electrically conductive trace extending from the connector substrate portion to the electrode carrying substrate portion, a first window formed in the connector substrate portion to expose the electrically conductive trace to form a connector pad, and a second window formed in the electrode carrying substrate portion to expose the electrically conductive trace to form an electrode pad. The electrode lead may further comprise a lead connector that incorporates the connector substrate portion.
