CorTec Brain Interchange

CorTec (Freiburg, Germany) describes Brain Interchange as a fully implantable, wireless, closed-loop system for pre-clinical and clinical research toward therapies for neurological diseases. It holds two FDA Breakthrough Device Designations (second announced Aug 31, 2026) and is described by the company as the first European implantable BCI with an FDA-approved (IDE) US trial, lead indication stroke rehabilitation.

Human use so far

  • A University of Washington lab reported cursor control by its first participant (Apr 2026) [5].
  • In an Oct 2026 Badische Zeitung interview, Schuttler said stroke patients steered the computer game Pong by thought alone and that targeted stimulation supported relearning of movements; regional-press interview, not peer reviewed [4].
