Vielight Awarded Patent for Photobiomodulation-Based Vagus Nerve Stimulation Device

Vielight Inc. has been issued a utility patent for Vielight Vagus, the first photobiomodulation (PBM)-based vagus nerve stimulation (VNS) system designed for trans-cervical application.

The Vielight Vagus represents a next-generation, non-invasive VNS modality that combines the safety and bioenergetic advantages of PBM with the benefits of cervical vagus nerve stimulation. Compared to auricular or electrical cervical methods, it offers a comfortable, gel-free, and sensation-free experience with promising potential for autonomic and systemic benefits, according to the company. Its bilateral, 100-Hz pulsed approach—grounded in emerging science—provides an innovative path for heart-rate variability (HRV) modulation and neurophysiological enhancement. The device’s usability supports integration into home-based clinical research. VNS applications will be a focus of Vielight’s future investigations.

The vagus nerve is essential in regulating critical bodily functions, including mood, inflammation control, and overall homeostasis. Current methods of vagus-nerve stimulation often involve invasive surgical procedures or electrical approaches that can present challenges related to safety and user comfort. The Vielight Vagus offers a non-invasive alternative by utilizing pulsed near-infrared light, specifically targeting the cervical branches of the vagus nerve, coupled with intranasal application supported by evidence of systemic effects.

“Our mission at Vielight is to harness the power of light to enhance human health and well-being. With the Vielight Vagus, we are introducing a more user-friendly and accessible approach for managing autonomic balance, reducing systemic inflammation, and potentially improving mental health,” Vielight CEO Dr. Lew Lim said. “This patent approval is a significant milestone not only for our company but for individuals seeking non-invasive wellness solutions.”

The Vielight Vagus device is designed for easy home use, featuring a hands-free, battery-powered collar that ensures consistent anatomical placement for optimal targeting. Preliminary experimental outcomes indicate a notable increase in vagal tone at specific pulse frequencies, aligning with findings from existing electrical VNS research.

As a low-risk, general-wellness device, Vielight is not making direct medical claims regarding the Vielight Vagus. Clinical efficacy claims will be made only following rigorous studies and the necessary regulatory approvals.

Vielight Inc. advances health and wellness through photobiomodulation technology. The Toronto-based firm aims to provide non-invasive solutions that enhance quality of life and foster autonomy in health management.
