Brain implant for epilepsy tested in 20-minute surgery

The device was both placed and removed in just about 20 minutes, a quick turnaround for such a complex technology. This achievement is a big deal for Paradromics, which has been working on this brain implant technology for nearly 10 years. 

The device is still in the research phase and hasn't been approved by regulators. But the recent implant is a big step forward. 

"We've already shown in animals that our device is top tier for data quality and durability," said the company's founder and CEO, Matt Angle. "Now, we've shown it works in humans, too, which really builds momentum for our upcoming clinical trial."

The Connexus BCI stands out because it's engineered for durability and packed with cutting-edge features. One of its most notable innovations is the inclusion of 421 microelectrodes, each one thinner than a human hair, which allows the device to capture signals from individual brain cells with impressive precision. These electrodes are housed in a body made from titanium and platinum-iridium, materials that are widely trusted in medical implants for their safety and compatibility with the human body, ensuring the device is suitable for long-term use. 

The Connexus BCI transforms brain activity into digital action through a simple yet sophisticated series of steps, each designed to make communication seamless for people with severe motor impairments.

Implant the device: A surgeon places the Connexus BCI under the skin, using techniques that are already well established in medicine.

Capture brain signals: The device's tiny electrodes pick up signals from individual neurons in the motor cortex.

Send data to the chest: These signals travel along a thin wire to a small device in the chest.

Wireless transmission: The chest device sends the data wirelessly to a computer or smartphone.

Turn thoughts into words: Advanced software figures out what the user wants to say or do and translates it into speech, text or digital commands.

For people who can't speak or move because of conditions like ALS or stroke, Paradromics' technology could be life-changing. It could let them communicate at natural speeds and even control computers with their thoughts.

The procedure was led by Dr. Oren Sagher, a professor of neurosurgery, and Dr. Matthew Willsey, an assistant professor of neurosurgery and biomedical engineering, both at the University of Michigan. Their team includes both doctors and engineers, making sure the implant was done safely and effectively. Dr. Willsey shared that the Paradromics device has over four times the number of sensors compared to other devices they've used, which means it can capture much more detailed brain activity.

Paradromics has raised almost $100 million so far and recently teamed up with Saudi Arabia's NEOM. The company is also part of a special FDA program that helps speed up the development of breakthrough medical devices. Later this year, Paradromics plans to start a clinical trial for people with severe movement problems from conditions like ALS, spinal cord injury or stroke. The goal is to help them communicate independently using digital devices.

Paradromics' first human implant is a big moment for the field of neurotechnology. While the device is still in the research phase, this successful test shows that it's possible to safely and effectively use advanced brain-computer interfaces in people. As Paradromics and other companies keep pushing forward, the future looks promising for people with severe motor impairments. The ability to communicate and interact with the world in new ways is closer than ever, and that's something worth talking about.
