Implantable electrode array assembly including a carrier, superstrates mounted to the carrier and electrodes disposed on the superstrates

An electrode array, said electrode array comprising:

• a flexible carrier having a surface;
• electrical conductors disposed within or on said carrier;
• a plurality of rigid superstrates formed from electrically insulating material that are disposed on the surface of said carrier, said superstrates being arranged on said carrier so that said carrier is able to flex wherein said superstrates have exposed surfaces;
• a plurality of spaced apart electrodes are disposed on the exposed surfaces of said superstrates and
• wherein, plural conductive vias extend through said superstrates on which said plural electrodes are disposed, each said via extending from a separate one of said electrodes so as to electrically connect each said electrode to a different electrical conductor disposed within or on said carrier so that different currents can be simultaneously sourced from/sunk to each electrode on the said superstrate.

An electrode array, said electrode array comprising:

• a flexible carrier having a surface;
• electrical conductors disposed within or on said carrier;
• a plurality of rigid superstrates formed from electrically insulating material that are disposed on the surface of said carrier, said superstrates being arranged on said carrier so that said carrier is able to flex wherein each said superstrate has an exposed surface;
• at least one electrode disposed on the exposed surface of said superstrates wherein, conductive vias extend through said superstrates on which said electrodes are disposed so as to electrically connect said electrodes on said superstrates to at least one of said conductors disposed within or on said carrier;
• and
• at least one post extends from at least one said superstrate on which a said electrode is disposed, said post extending at least partially through said carrier so as to hold said superstrate to said carrier.
