A flexible circuit electrode array 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; and a central opening in
the area of the metal traces. A flexible circuit electrode array
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; and a soft polymer filling an attachment point. A flexible
circuit electrode array 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; and a hump to avoid a touching of the
flexible electrode array and the optic nerve.
