Brain Interchange System

Developed with the community and for the community.

The Brain Interchange System enables interconnection of the nervous system to external information technologies. An interchange of information is realized to modulate the nervous system.

The Brain Interchange System is available for pre-clinical and clinical research. It can be used to develop novel therapies for neurological diseases.

Implantable System

As an investigational device, the fully implantable system is designed for both recording and stimulating on 32 channels. The Brain Interchange ONE is the first implantable version of the system technology that is available for clinical and pre-clinical research. It features fully wireless functionality for chronic open- and closed-loop interaction with the nervous system.

Bench-Top System

The Brain Interchange Evaluation Kit is a bench-top-version of the system, which is electrically identical to the implant. The Evaulation Kit is the ideal entrance to the clinical use of the Brain Interchange Implantable System.
