Abstract:
1. A method of manufacturing an insulated flexible electrical circuit suitable for implantation in living tissue comprising: providing a substrate; depositing by vapor deposition a first polyparaxylylene layer, 0.5 to 50 microns thick on the substrate; depositing an electrical conductor layer on the first polyparaxylylene layer; patterning the electrical conductor layer to form traces; depositing a second polyparaxylylene layer, 0.5 to 50 micros thick, on the first polyparaxylylene layer and on the traces, the second polyparaxylylene layer defining at least one aperture that exposes the traces suitable for electrical communication with living tissue, and removing the first polyparaxylylene layer, traces and second polyparaxylylene layer from the substrate; wherein the first and second polyparaxylylene layers support the traces.
