Title:

FLEXIBLE ELECTRODE ARRAY FOR ARTIFICIAL VISION

Document Type and Number:

WIPO Patent Application WO2003043529

Kind Code:

B1

Abstract:

An image is captured or otherwise converted into a signal in an artificial vision system. The signal is transmitted to the retina utilizing an implant. The implant consists of a polymer substrate made of a compliant material such as poly(dimethylsiloxane) or PDMS. The polymer substrate is conformable to the shape of the retina. Electrodes and conductive leads are embedded in the polymer substrate. The conductive leads and the electrodes transmit the signal representing the image to the cells in the retina. The signal representing the image stimulates cells in the retina.
