ABSTRACT OF THE DISCLOSURE A small diameter, rolled-up electrode array for implantation in the cochlea is provided herein. The array includes a flexible, biologically-inert, planar support member which has been rolled up to a cylindrical shape to have a proximal end and a distal end. A plurality of electrodes is located at predetermined, spaced distances along a portion of the length of the rolled-up, cylindrically-shaped support member, each of the electrodes comprising an open-ended ring almost encircling the support member and a conducting feedline monolithically associated with each electrode on the feedline, the feedline preferably being integral with each associated electrode. Each electrode lies on the curved outer surface of the rolled-up cylindrical support member, and extends from the proximal end of each associated electrode to the associated distal end. The support member is thus rolled-up to facilitate insertion of the electrode array into the cochlea while minimizing trauma during the insertion procedure.
