Abstract
A stealthy conductor that may be placed inside a fascicle in the peripheral nervous system (PNS) is described. The conductor is placed using a targeted-fascicle or targeted-axon approach to improve specificity and signal to noise ratio (SNR). The conductor is part of a targeted fascicular interface device and is placed using an insertion tool in a manner that reduces nerve damage as compared to conventional systems. The conductor is so small (e.g., <10 μm diameter) and so flexible (e.g., approximates flexibility of surrounding neuronal material) that biological reactions (e.g., recruitment of macrophages, edema) to the presence of the conductor may be reduced. The targeted fascicular interface device has an insulated portion and a non-insulated portion that may act as an electrode. The insulated portion may include materials that promote healing at the entry/exit site and that adhere to the perineurium.
