ABSTRACT:
The present invention provides a flexible circuit electrode array adapted for neural stimulation, comprising: a polymer base layer; metal traces deposited on said polymer base layer, including electrodes suitable to stimulate neural tissue; a polymer top layer deposited on said polymer base layer and said metal traces at least one tack opening; wherein said polymer base layer, said metal traces and said polymer top layer are thermoformed in a three dimensional shape.The present invention provides further a method of making a flexible circuit electrode array comprising depositing a polymer base layer; depositing metal on said polymer base layer; patterning said metal to form metal traces; depositing a polymer top layer on said polymer base layer and said metal traces; preparing at least one tack opening; and heating said flexible circuit electrode array in a mold to form a three dimensional shape in said flexible circuit electrode array.
