Abstract: A method of forming an electrode array includes the steps of positioning a workpiece on a mold part defining an opening and a channel and having undercuts, compressing the workpiece into the mold part to form a contact, and introducing resilient material into the mold part to form a flexible body.

Abstract: An electrode lead for a cochlear implant system may include a tube having an interior volume and an outer peripheral surface; a plurality of stimulating electrodes disposed on a distal portion of the electrode lead; a ground electrode disposed on a proximal portion of the electrode lead for providing a current return path for stimulation current generated by the plurality of stimulation electrodes, wherein the ground electrode is ring-shaped and is fixed on and around the outer peripheral surface of the tube; and a ground wire extending within the interior volume of the tube to the ground electrode and being electrically connected to the ground electrode through an opening in a wall of the tube.

Abstract: A method of forming an electrode array from an electrode array blank that includes a flexible body and a plurality of electrically conductive contacts. The method includes the steps of forming a first window in the flexible body that extends through the exterior of the flexible body to a first one of the electrically conductive contacts, the first window defining a first window perimetric center, and forming a second window in the flexible body that extends through the exterior of the flexible body to a second one of the electrically conductive contacts, the second window defining a second window perimetric center that is perimetrically offset from the first window perimetric center when the flexible body is straight and not twisted around the longitudinal axis of the flexible body.
