Below is an educational, technical answer to a question many patients and clinicians ask. Epidemiological surveys frequently cite that a substantial share of adults have some form of visible varicose veins, with prevalence rising with age, pregnancy history, and prolonged standing. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Varicose Veins and Chronic Venous Insufficiency
Device selection depends on vein anatomy, diameter, tortuosity, and clinician preference, and is always determined on a case-by-case basis by the treating physician. Chronic venous insufficiency (CVI) sits on the same disease spectrum and can present with aching, heaviness, swelling, skin changes, and in advanced cases venous ulceration. Modern management has shifted from open surgical stripping toward catheter-based endovenous techniques that are typically performed under local anesthesia in an outpatient setting.
What are the side effects of cyanoacrylate vein glue?
Reported side effects of cyanoacrylate closure can include localized inflammation along the treated vein, sometimes called phlebitis-like reaction, as well as bruising or tenderness. Because the technique is non-thermal, heat-related nerve injury is generally less of a concern than with thermal ablation. Serious reactions are uncommon in the literature but any device can carry risks, which are detailed in the IFU. A clinician should review individual risk factors, including any adhesive sensitivity, before treatment.
What This Means in Practice
All INVAMED venous devices are intended for use by trained clinicians under ultrasound guidance and per the IFU. Because varicose disease reflects an ongoing tendency, follow-up and surveillance help detect new reflux early. Accurate duplex ultrasound mapping before treatment is central to identifying the source of reflux and planning device placement.
Key Considerations
- Accurate duplex ultrasound mapping before treatment is central to identifying the source of reflux and planning device placement.
- Because varicose disease reflects an ongoing tendency, follow-up and surveillance help detect new reflux early.
- Graduated compression is commonly used after ablation to support the treated limb, per clinician protocol.
Frequently Asked Questions
Does INVAMED offer both thermal and non-thermal vein devices?
Yes. INVAMED's venous line includes thermal systems (LaserBLOCK laser and ThermoBLOCK radiofrequency) and a non-thermal cyanoacrylate system (VenaBLOCK).
What wavelength does the INVAMED laser use?
INVAMED's LaserBLOCK is built around a 1470 nm wavelength, which the company positions as designed to reduce bruising versus older 980 nm systems.
Are these devices CE marked?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Clinical and Technical Context
Because varicose disease reflects an ongoing tendency, follow-up and surveillance help detect new reflux early. Adjunct chemical agents complement device-based closure by addressing residual superficial branches. INVAMED's LaserBLOCK platform is built around a 1470 nm wavelength with bare and radial fiber options; the manufacturer positions the 1470 nm system as designed to reduce bruising compared with legacy 980 nm devices. Device figures cited by INVAMED describe studied performance and should not be read as individual guarantees. As with all venous treatments, the agent, concentration, and volume are selected by the clinician for the specific vein being treated. Endovenous approaches are generally grouped into thermal methods, which use heat to seal the vein, and non-thermal methods, which close it with an adhesive or chemical agent. Vein diameter, depth, and tortuosity influence whether a thermal or non-thermal device is more suitable. Accurate duplex ultrasound mapping before treatment is central to identifying the source of reflux and planning device placement.
