Google patents ultra-thin film leads for brain implants

Patent drawing from the official filing.

This filing describes a method for making very thin, flexible wires used in brain implants. The design uses a supporting structure with specific features to help it stick securely to a backing layer during manufacturing.

Why it mattersIt could lead to more durable and flexible devices for monitoring or stimulating the nervous system.

In the filing’s own words

The present disclosure relates to thin-film lead assemblies and neural interfaces, and methods of microfabricating thin-film lead assemblies and neural interfaces. Particularly, aspects of the present disclosure are directed to a thin-film neural interface that includes a proximal end, a distal end, a supporting structure that extends from the proximal end to the distal end, one or more of conductive traces formed on a portion of the supporting structure, one or more electrodes formed on the front side of the supporting structure in electrical connection with the one or more conductive traces, and a backing formed on the back side of the supporting structure. The supporting structure comprises one or more features to facilitate mechanical adhesion between the supporting structure and the backing.
