Regenerative microchannel electrode implant.
(A) Concept drawing of the microchannel implant. The sciatic nerve is sectioned with each stump sutured into the implant, separated by an array of parallel microchannels. (B) Exploded, schematic view of the implant 14 elastomeric layers. The implant consists of 2 × 4 bonded rows of PDMS, each containing 10 microchannels. The microchannels are 110 μm × 120 μm, with a wall thickness of 50 μm. (C) Picture of the middle row of microchannels with integrated electrodes. (D) Picture of the complete elastomer-based microchannel electrode implant. The gold traces connecting to the electrodes extend out of the device and are interfaced to highly flexible wires with conductive paste.
