From Clinical Legacy to Everyday Wellness

EVANES is the modern evolution of the SaluStim G1 and Parasym™ — devices trusted in hundreds of clinical studies. Rooted in science, redesigned for life.

The Origin Story

Where It All Began

The foundation for EVANES began in 2011 with clinical research into non-invasive auricular vagus nerve stimulation. In 2014, our team developed the original SaluStim G1 device — a safe and effective taVNS solution — using modified TENS technology and a custom-designed ear electrode.

During early distribution, the same device was co-branded and marketed in the UK under the name Parasym™, helping to grow global awareness of taVNS therapies. While the paths eventually diverged, both devices share the same clinical roots.

Today, EVANES builds on that legacy — redesigned and refined by the original SaluStim team, with the knowledge and experience gained from over a decade of research and patient care.

Used in 50+ peer-reviewed clinical studies

Trusted by leading universities and hospitals

Developed with a focus on safety, accessibility, and precision

Parasym™, Nurosym™ & the Transition

What About Nurosym?

Nurosym™ appears to be an updated version of Parasym™, with a sleeker design and consumer-oriented branding. While the full technical specifications of Nurosym are not publicly disclosed, it is widely understood to be built on the same taVNS foundation co-developed by the SaluStim team.

Today, both Parasym and Nurosym continue to represent the first wave of consumer-accessible vagus nerve stimulation — but the world of wellness has evolved.

The Next Generation — EVANES

EVANES

Introducing EVANES

EVANES represents the next generation of wearable taVNS technology. Built by the same minds behind SaluStim and Parasym, EVANES is:

  • Scientifically grounded

  • Updated with BioSync technology for optimized stimulation

  • Lightweight and 100% wireless, all-in-one mobile device

  • Designed for everyday stress and anxiety relief, focus, and autonomous nervous system balance

EVANES is everything Parasym and Nurosym were — and more.
