CorTec (Germany) is developing the Brain Interchange System, a platform positioned for implantable, wireless, closed-loop neurotechnology research and (eventually) therapies.

What they’re building

CorTec describes Brain Interchange as a system for pre-clinical and clinical research to develop therapies for neurological diseases.

First-in-human milestone (reported)

BioWorld reported that CorTec implanted its Brain Interchange BCI system into a stroke patient in late July 2025.

Why it matters

A lot of BCI discourse is dominated by “assistive” use cases (cursor control, typing). CorTec sits closer to the therapeutic / closed-loop lane, where the key engineering questions are:

stable long-term recording
safe stimulation
telemetry / power
clinical reliability and workflow

What to watch

Indications and trial design What is the first target (stroke rehab, epilepsy, movement disorders, etc.) and what are the endpoints?
Closed-loop performance How are biomarkers defined, detected, and used to control stimulation in real time?
Device practicality Implant size, longevity, recharge strategy, reliability, and surgical burden.

Notes on sourcing

Draft. Current sources are a short BioWorld report and CorTec’s public-facing site. We should add primary clinical-trial registry entries and peer-reviewed publications as we collect them.
