CorTec's Brain Interchange™ BCI System Enables Stroke Patient to Control Computer with his Mind
CorTec’s Brain Interchange™ enabled a stroke patient to control a computer through thought alone – including a game of Pong – using the exact same fully implanted, wireless device already supporting his motor recovery. No additional surgery. No separate hardware.
To our knowledge, the first fully implanted, wireless BCI system worldwide to demonstrate this dual capability in a single patient.
CorTec’s Brain Interchange™ Accepted into FDA Total Product Life Cycle Advisory Program (TAP)
In April 2026, CorTec’s Brain Interchange received acceptance into the FDA Total Product Life Cycle Advisory Program (TAP), following the FDA Breakthrough Device Designation granted earlier the same month. A third participant has been successfully implanted at Harborview Medical Center in Seattle as part of the ongoing NIH-funded, FDA-approved clinical trial.
CorTec Receives FDA Breakthrough Device Designation for Its Brain Interchange System in Stroke Rehabilitation — the First BCI Worldwide Designated for Stroke Motor Rehabilitation
The U.S. Food and Drug Administration (FDA) has granted Breakthrough Device Designation for CorTec’s Brain Interchange™ system. The designation covers the use of direct cortical electrical stimulation to support motor recovery in people living with chronic stroke-related impairments.
CorTec Announces Successful Second Human Implantation of Its Brain-Computer Interface (BCI) System
In February 2026, a second patient at Harborview Medical Center in Seattle successfully received the Brain Interchange™ implant as part of an NIH-funded, FDA-approved trial led by researchers from the University of Washington and UCLA. Building on encouraging results from the first participant, the study continues to advance CorTec’s clinical program for stroke recovery.
„This therapy literally brought me back from the dead"
In December 2025, the University of Washington shared the story of Matt Kidd, a stroke patient who regained motor function as part of a clinical trial using a brain implant developed in collaboration with CorTec. After years of therapy with little progress, targeted electrical stimulation helped his nerve cells reconnect and within weeks he was able to perform everyday movements again.
CorTec Announces Neurotech Milestone: First Human Implantation of a Brain-Computer Interface made in Germany
In July 2025, CorTec achieved a historic milestone with the first-ever human implantation of a fully implantable, German-developed Brain-Computer Interface system, performed at Harborview Medical Center in Seattle. As part of an FDA-approved trial led by researchers from the University of Washington and UCLA, the study targets motor recovery in stroke patients and marks a major step forward in neurorehabilitation.
CorTec Receives FDA Approval for First-in-Human Implantation of the Brain Interchange™ System
In October 2024, CorTec received both FDA Investigational Device Exemption and IRB approval from the University of Washington, clearing the path for the first-ever human implantation of a fully implantable, German-developed Brain-Computer Interface system. The study, conducted in collaboration with researchers from the University of Washington and UCLA, targets motor recovery in stroke patients with arm paralysis.
