Cortigent reports six-year results for its Orion visual cortex implant
All six blind participants performed better on visual tasks with the device on, and fewer than 4% of electrodes failed over the study.
Cortigent, a Vivani Medical subsidiary, has presented final results from the six-year early feasibility study of Orion, a visual prosthesis that stimulates the visual cortex. The results were shown at the North American Neuromodulation Society meeting. All six participants, implanted in 2018–2019, did better on visual tasks with the device switched on. Fewer than 4% of electrodes stopped working over the study, and the one serious adverse event, an early seizure, was managed by adjusting stimulation.
Long-term durability data like this is rare for brain implants and supports the next generation of cortical vision devices.
