Abstract
Official abstract text for this publication.
The present invention is a flexible circuit electrode array with a polymer base layer, metal traces deposited on the polymer base layer, including electrodes suitable to stimulate neural tissue, a polymer top layer deposited on the polymer base layer and the metal traces, and a soft polymer filling a void through both the polymer base layer and polymer top layer, the soft polymer forming drum stress relief around an attachment point.
First claim
Opening claim text (preview).
The invention claimed is: 1. A flexible circuit electrode array comprising: a polymer base layer, comprised of a first hard polymer, configured to support traces; metal traces deposited on said polymer base layer, including electrodes configured to stimulate neural tissue; a polymer top layer deposited on said polymer base layer and said metal traces, said polymer top layer defining electrode voids to expose the electrodes, wherein the polymer base layer, metal traces, and polymer top layer form a flexible circuit and include an attachment point void through both the polymer base layer and polymer top layer that is separate from said electrode voids; and a soft polymer membrane configured to be penetrated by a retinal tack, wherein the soft polymer membrane is adhered to the flexible circuit below a surface area configured to be closest to a retina and across the attachment point void, the soft polymer membrane being softer than the hard polymer. 2. The flexible circuit electrode array according to claim 1 , wherein said soft polymer membrane comprises at least one of the following polymers; polyimide, silicone, polyurethane, Parylene, polyethylene, polypropylene, polyamide, polyester, PEEK, or mixtures thereof. 3. The flexible circuit electrode array according to claim 1 , further comprising a hole in the soft polymer membrane configured to receive a retinal tack. 4. The flexible circuit electrode array according to claim 1 , wherein the hard polymer is polyimide and the soft polymer membrane is silicone.
