Array of bipolar electrodes
First Claim
1. An array of bipolar electrodes comprising:
- a molded carrier member having a surface and a core, said member including at least one pair of electrodes molded therein, at least one electrode of said pair of electrodes comprising a length of contact material which is planar in a longitudinal direction of said carrier member and is formed in a semicircular shape having a convex contact surface constituting only a portion of said length of contact material and a locking portion defining an internal space, said contact material molded in said carrier member with said contact surface being the only portion of said contact material exposed at said member surface, the locking portion of said contact material being molded entirely into the core of said carrier member, said contact material connected to a lead wire molded in the core of said carrier member.

Abstract
The invention provides an array of electrodes suitable for use as an auditory prosthesis. The array comprises a carrier member formed from electrically insulating flexible material, having a surface and a core, the carrier member including at least a pair of electrodes molded therein, the electrodes comprising a length of contact material formed in a semi-circular shape, having a convex contact surface and a locking portion defining an internal space. The electrode is molded in the carriers so that the convex contact surface of the electrode is preferably flush with the carrier member surface. The locking portion of the electrode is molded into the core of the carrier member in the electrode connected to a lead wire which is molded in the core of the carrier member. The invention further provides a method for fabricating such an array of bipolar electrodes.
