Regenerative peripheral nerve interface
First Claim
1. A regenerative peripheral nerve interface (RPNI) for a subject comprising:
- an insulating substrate and at least one metallic electrode disposed on or in the insulating substrate, so that the insulating substrate and the at least one metallic electrode define a thin-film array;
a layer of decellularized biotic material comprising decellularized small intestinal submucosa (SIS); and
at least one conductive polymer.

Abstract
The present disclosure provides a regenerative peripheral nerve interface (RPNI) for a subject comprising an insulating substrate, at least one metallic electrode deposited onto the insulating substrate forming a thin-film array; a portion of the at least one metallic electrode surface having a layer of a first conductive polymer and a layer of decellularized small intestinal submucosa (SIS) coating a portion of the electrode, wherein a second conductive polymer is electrochemically polymerized through the SIS to form the regenerative peripheral nerve interface. The present disclosure also provides that a layer of muscle tissue contacts the regenerative peripheral nerve interface.
