We're bringing the nervous system back to calm.
Elfoyo builds Nuvora — a medical device that reaches the vagus nerve exactly where it runs closest to the surface: the upper neck. Calmer days, deeper sleep, energy back.
Four years, logged.
The problem, the mission, the vision.
Your body is stuck in alarm.
Chronic stress keeps millions in fight-or-flight — a racing heart, shallow sleep, no energy, a mood that won't lift. Most solutions work on the mind. Almost none reach the nerve that tells your body it's safe.
Our goal: 1 million calmer nervous systems.
43,200+ people have already started. We won't stop until one million have their vagal tone back — measurably, one session at a time.
Nervous-system care, as normal as brushing your teeth.
15–20 minutes a day, in the evening, on the couch. We want caring for your vagus nerve to feel as ordinary as caring for your teeth.
We're not in the quick-fix business. We're switching the body's brake back on.
Quick fixes numb the alarm for a few hours. We think that's the wrong model entirely. Your vagus nerve is the body's built-in brake — and like a muscle, it responds to training.
Nuvora reaches it at the upper neck (C0–C2) with three methods at once: TENS signals "you're safe", EMS releases the muscles pressing on the nerve, and 108°F deep heat activates the rest system.

One nerve. Eight ways you feel it.
The vagus nerve connects your brain to your heart, gut and lungs. When it's back online, the whole body notices.
The heavy, flat feeling starts to lift.
Less inner alarm, fewer racing thoughts.
From "on guard" to rest — fall asleep and stay asleep.
The energy that sleep alone never gave back.
A calmer system thinks clearer.
Your heart's built-in brake, back online.
"Rest and digest" isn't a metaphor.
The measurable marker of a stronger nervous system.

Built in the USA. One mission.
Neuroscientists, clinicians, engineers and patient-care specialists — all working on one thing: getting your nervous system out of alarm, safely and measurably.
One team. One nerve.
The principles we build by — not a poster on the wall, just what it takes to make a medical device people trust with their nervous system.
We follow the evidence
If the data doesn't support it, we don't say it — and we don't build it.
We listen to patients
Every feature starts with someone's real 3 a.m. struggle, not a marketing idea.
We build safely
Medical-grade from day one: ISO 13485 quality and IEC 60601 electrical safety.
We improve fast
Test, learn, refine. Better beats perfect — but never at the cost of safety.
We keep it simple
15–20 minutes on the couch in the evening. No complicated routines, no learning curve.
We own it
From the first prototype to your doorstep — and every question after — we see it through.
