1. A method of making an electrode array so that it assumes a curved shape after straightening, comprising:

  • forming a straight electrode/wire assembly having a plurality of electrode strips spaced apart a predetermined distance, each strip having at least one insulated wire electrically connected thereto;

    compressing a silastic tube onto an oversized straight mandrel such that the tube is compressed in length by approximately 10-40%;

    fusing the straight electrode/wire assembly to the compressed silastic tube on the straight mandrel to form an electrode array; and

    removing the mandrel;

    whereupon compression forces associated with the compressed silastic tube force the electrode array to assume a curved shape.
