One year down, a lifetime to go. New results from Synchron’s first human study of its brain-computer interface system—a permanent, stent-like implant—found that one year after the device’s placement, none of the four participants had experienced any adverse events that led to disability or death.

The Stentrode system reaches the brain via the jugular vein through a minimally invasive, two-hour procedure that stands in stark contrast to most other operations under development, which typically require physicians to drill through the patient’s skull. Once in place, the Stentrode expands to fit flush against the blood vessel’s walls, where its sensors can pick up the brain’s neurological signals.
