Connexus - Brain-Computer Interface (BCI) for Motor-Impacted Communication

FromParadromics

SHARE

The Connexus Brain-Computer Interface (BCI) is designed to assist individuals with motor impairments, such as those resulting from ALS, spinal cord injuries, or strokes, in re-establishing communication through advanced technology. By decoding neural signals into synthesized speech, text, and cursor control, Connexus provides a significant leap in BCI technology. It is built to endure long-term medical use with high data-rate capabilities, ensuring performance optimization during natural communication speeds and complex interactions with digital devices. The device integrates a miniaturized cortical module with an array of 421 microelectrodes designed to capture extensive neural data. These electrodes, made from medically proven materials like a titanium alloy body and platinum-iridium electrodes, are biocompatible and thinner than human hair, ensuring a non-invasive and effective interface. The system comprises an internal transceiver and extension lead for signal transmission and power supply, leveraging wireless technologies akin to smartphone charging. Connexus is currently undergoing clinical trials and is not yet for sale in the United States.

Communication is a fundamental human need. The inability to express yourself with family and friends or request basic needs makes living difficult. For people with motor conditions caused by ALS, spinal cord injury, or stroke, speaking or using the computer may be impossible.

Connexus enables motor-impaired people to communicate again and to independently use a computer by translating neural signals into synthesized speech, text, and cursor control.

Paradromics combined advanced neuroscience with medical device expertise to create Connexus, leaping beyond 30 years of brain-computer interface (BCI) research.

Built for long-term medical use, Connexus is the first high-data rate BCI designed to deliver high performance for the user.

A neurosurgeon places the Connexus BCI system under the skin: cortical module, internal transceiver, and extension lead. The surgery uses well-developed techniques common in other healthcare applications.
The microelectrodes of the cortical module extend just below the brain’s surface to gather rich signals from individual neurons in the motor cortex.
This data is sent along a thin, flexible lead to a transceiver in the chest. This disk-shaped transceiver wirelessly transmits data by a secure optical link to a second transceiver worn by the user. The second transceiver powers the system through inductive charging, similar to wireless charging for smartphones.
The data is then sent to a small computer loaded with advanced language models and AI. The software analyzes the user’s brain data to figure out what they intend to say or do and translates into words (text on a screen or synthesized speech) or enables control of digital devices.
