Voltran is INVAMED's intranasal phototherapy system, designed as a non-pharmacological option that healthcare professionals may discuss with patients managing allergic rhinitis. This article provides a technical overview of the device's design and mechanism of action, intended for clinicians evaluating phototherapy-based approaches for allergic rhinitis care.
What Is the Voltran System?
Voltran is a soft-laser intranasal phototherapy device developed specifically for application to the nasal mucosa in patients with seasonal or perennial allergic rhinitis. The system combines narrow-band UVB, visible light, and infrared wavelengths, with a visible-light component operating around 630 nm, delivered directly to the nasal mucosa through an intranasal applicator. Each session is designed to be brief, generally described as approximately five minutes, and is intended to be non-heat-generating at the tissue level, meaning it is not designed to produce a thermal or ablative effect during application.
How Does the Device's Mechanism of Action Work?
Voltran's intended mechanism involves localized phototherapy effects on immune cells present in the nasal mucosa, including mast cells, T lymphocytes, and eosinophils, which are all implicated in the allergic inflammatory cascade. The general concept described by INVAMED is that combined UVB, visible, and infrared wavelengths are intended to reduce histamine production and release at the mucosal level, with the goal of limiting the local allergic inflammatory response associated with rhinitis symptoms. This mechanism is described as non-invasive and is positioned as a drug-free option within the broader landscape of allergic rhinitis management strategies.
What Are the Device's Key Design Characteristics?
Based on INVAMED's product materials, Voltran's design is generally characterized by:
- Combined wavelength technology — narrow-band UVB, visible light (approximately 630 nm), and infrared delivered together
- Intranasal applicator — designed to target the nasal mucosa directly
- Short session duration — sessions described as approximately five minutes
- Non-thermal application — designed not to generate a heat sensation or tissue damage during treatment
- European market authorization — authorized for the European market under the applicable European medical device regulations, with availability and indications varying by country
What Is the Device's Intended Clinical Role?
Voltran is intended to be discussed as one option among several that physicians may consider for patients with allergic rhinitis, alongside pharmacological approaches such as antihistamines or intranasal corticosteroids, and alongside procedural options such as radiofrequency turbinate reduction. It is not positioned as a replacement for physician-directed allergy management but as an additional non-pharmacological option that can be discussed based on individual patient presentation, preferences, and treatment history. As with all procedures and devices, suitability is determined by a physician, and use is intended for trained healthcare professionals following the official Instructions for Use (IFU).
Frequently Asked Questions
Is Voltran intended to replace antihistamines or nasal steroids?
No. Voltran is generally described as an additional, drug-free option that physicians may discuss alongside — not necessarily instead of — pharmacological approaches, depending on the individual patient's presentation and treatment history.
What wavelength technology does Voltran use?
Voltran combines narrow-band UVB, visible light (around 630 nm), and infrared wavelengths delivered to the nasal mucosa through an intranasal applicator, according to INVAMED product materials.
How long does a typical Voltran session take?
Sessions are generally described as approximately five minutes, and the device is designed to avoid generating a heat sensation or tissue damage during application.
