Circumferential Neural Interface

Overview

Circumferential neural interfaces are thin, malleable, low-impedance devices that wrap completely around nerves or spinal cord structures to achieve high-resolution recording and stimulation without penetrating nerve tissue.

Circumferential peripheral nerve implants

We have developed a circumferential interface for recording sensory signals and delivering motor stimulation at sub-nerve fascicle resolution.

Circumferential spinal cord implants

Our i-360 technology is the first interface for simultaneous recording and stimulation across all anatomical surfaces of the spinal cord.
