The brief

Analyst view

• Beinao-1 is a semi-invasive system placed on the brain's outer membrane, reducing surgical risk compared to invasive intracranial implants.
• 16 patients implanted by June 2026, with the longest implantation exceeding one year and over 55,000 hours of cumulative safe operation.
• Aims to complete enrollment for registered clinical trials in 2026 and seek medical device registration in 2027.

Technical approach

As reported

Electrode Array

128-channel epidural array

Flexible, ultra-thin electrode matrix with 128 channels positioned on the dura mater, outside brain tissue, reducing surgical risk.

Signal Decoding

Motor and speech decoding

System enables fine motor control for paralyzed patients and speech decoding for those unable to speak, with vocabulary of approximately 100 Chinese words.

Safety

Semi-invasive design

Placement outside brain tissue avoids penetrating the brain itself, reducing risk of tissue damage and long-term complications.
