NeuroXess Announces Breakthrough in Second Clinical Trial of Fully Implantable, Wireless, and Closed-Loop Brain-Computer Interface

NeuroXess announced today that following the completion of the first independently developed fully implanted, fully wireless, and fully functional ("three-all") brain-computer interface clinical implant by the end of 2025, a critical breakthrough has been achieved in the second clinical trial.Through the deep integration of 50-millisecond full-link ultra-low latency and Brain-Computer Interface-driven Functional Electrical Stimulation (BCI-FES) technology, a 29-year-old art teacher with high-level paralysis was able to achieve independent eating and painting creation.This marks the official entry of the technology into a new phase of clinical practical application and replicable promotion, laying a solid foundation for scaled application.

NeuroXess Completes Second "Three-All" Brain-Computer Interface Patient-Controlled Exoskeleton Drawing of Family Portrait

In product design, the system adopts flexible cortical electrodes, which are placed on the surface of the cortex under the dura mater, without invading brain tissue. It precisely collects signals while safeguarding the brain to the greatest extent.The surgery follows a mature paradigm of Deep Brain Stimulation (DBS) surgery, ensuring safety and reproducibility. The innovative split design places the battery module under the skin of the chest, keeping the heating unit away from the brain to avoid high-temperature risks, significantly enhancing safety.As the first brain-computer interface system in China and the second globally with a built-in battery, "Sanquan" achieves truly independent energy storage operation, free from cable constraints on the body surface, and stable support for daily use with short wireless charging.Compared with traditional devices that rely on external power supply, are restricted by cables, and become ineffective once disconnected, the "three-all" brain-computer interface makes it possible for patients to move freely, bringing them closer to real-life scenarios.

Technically, from signal acquisition, intent decoding, command transmission to terminal execution, the full-link latency is less than 50 milliseconds, truly achieving "thoughts at will."——The moment the patient's brain generates the intention to hold a pen, the hand has already started moving simultaneously. The thought instantly translates into action, delivering a natural and smooth brain-control experience. This indicator has reached an internationally leading level in the latency control of implantable brain-computer interfaces.

More groundbreaking is that this clinical trial, for the first time, adopted brain-computer interface-driven functional electrical stimulation technology (BCI-FES), deeply integrating the "Three-Whole" system with functional electrical stimulation (FES) technology to build a complete closed loop of "Thought-Decoding-Stimulation-Movement.": Precise acquisition and real-time interpretation of motor intentions through cortical electrodes, bypassing the damaged spinal cord, and precise stimulation of peripheral muscles to achieve natural and coordinated finger movements. Clinical validation shows that one month after surgery, patients have achieved precise active grasp of the affected hand through mind control, allowing them to independently complete high-precision tasks such as writing and drawing, truly returning control to the patient's own limbs.

NeuroXess's exploration always revolves around the core of "actual patient benefits."For this art teacher and new dad, the brain-computer interface has brought not only a restart of function but also a complete return to his professional and familial roles. With the help of mind control, he achieved self-feeding; relying on BCI-FES technology, he used his own hand to pick up a pen again, drawing family portraits and writing blessing cards.Those moments of companionship once lost to illness have now regained their warmth and color. With technology as a force for good, he has taken up the pen anew, transforming from someone who was cared for into a creator and protector.

Milestone Significance: China's Brain-Computer Solution Moves Towards Large-Scale Application

As the second case of the "three-all" brain-computer interface clinical trial in China, this trial successfully verified the stability and universality of the "three-all" system across different individuals.This has laid a technical foundation for subsequent multi-center large-scale clinical trials; at the same time, it has established the gold standard for clinical practical application of "full wireless, ultra-low delay, closed-loop control," paving the way for the global track of China's solutions in the field of neurorehabilitation.

NeuroXess Founder and Chief Scientist Tao Hu said: "The first clinical trial proved that it can be done, and the second clinical trial proved that it is effective and can be promoted.""From controlling external machinery to driving their own limbs, every step of our iteration closely meets clinical needs. Our goal is not only to enable patients to move again but also to help them return to life with quality and dignity."
