The brief

Analyst view

• Orion uses 60 micro-electrodes implanted on the visual cortex to generate phosphenes (points of light) perceived by blind patients.
• Six-year feasibility study (2018-2025) showed all six subjects improved with the system on versus off in visual function tests.
• Devices remained operational with fewer than 4% electrode loss; next step is planning pivotal trial for FDA marketing approval.

Technical approach

As reported

Implant

Micro-electrode array on visual cortex

60-electrode array placed on visual cortex. Each electrode stimulates a small neuron population.

Processing

Wireless belt-worn unit

A small processor worn on the belt captures video from a camera in glasses and converts it to wireless stimulation commands sent to the implant.

Vision

Phosphene pattern recognition

Each electrode creates a phosphene—perceived as a spot of light. 60 electrodes together create a pattern the brain interprets as real-time video.
