title: Cylindrical cochlear electrode array for use in humans.
abstract: This report describes the fabrication of a flexible multichannel electrode array suitable for use in humans. The conductors, pads, and stimulating tips are made of platinum on a polyimide substrate. Photolithographic techniques are employed in the fabrication of the electrode on a planar surface in the form of a film. The film is rolled subsequently into a cylinder of diameter 0.50 mm and the cylinder is filled with medical grade silicone rubber. The stimulation pads then form rings around the cylinder. In vitro and in vivo tests are ongoing with good results so far.
