This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating varicose vein devices. 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
Varicose veins are enlarged, twisted superficial veins that develop when the one-way valves inside leg veins no longer close properly, allowing blood to pool — a process clinicians call venous reflux. 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. 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.
Regulatory Status and Manufacturing
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Portfolio and Sizing
Within this category, INVAMED lists devices such as VenaBLOCK Non-Thermal Treatment for Vein Disease & Varicose Veins, ThermoBLOCK Varicose Vein Radiofrequency Ablation System, ThermoBLOCK Thermal Coagulation RF Ablation Small Vein Needle, LaserBLOCK Varicose Vein Laser System, LaserBLOCK Endovenous Bare & Radial Fiber Optics, VeinOFF Varicose Vein Treatment Agent. Size ranges, materials, and configurations are detailed in product documentation and the applicable IFU.
Key Considerations
- Accurate duplex ultrasound mapping before treatment is central to identifying the source of reflux and planning device placement.
- Graduated compression is commonly used after ablation to support the treated limb, per clinician protocol.
- Device figures cited by INVAMED describe studied performance and should not be read as individual guarantees.
Frequently Asked Questions
Is endovenous ablation done as day surgery?
Endovenous ablation is typically an outpatient, minimally invasive procedure performed under local anesthesia, though the exact setting is determined by the clinician and facility.
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.
Clinical and Technical Context
All INVAMED venous devices are intended for use by trained clinicians under ultrasound guidance and per the IFU. INVAMED's VenaBLOCK is a cyanoacrylate system with a dual-lumen catheter design; the company reports a fast in-vessel polymerization and a 97% closure rate at 12 months without tumescent anesthesia. Graduated compression is commonly used after ablation to support the treated limb, per clinician protocol. 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. The absence of thermal energy means nerve-injury risk associated with heat is generally reduced, though suitability still depends on individual anatomy. INVAMED reports 95%+ efficacy for saphenous reflux with ThermoBLOCK; as with all such figures, real-world outcomes are determined by patient selection and technique. Sealing the refluxing axial vein is intended to reduce the venous hypertension that drives symptoms and visible tributaries. Modern management has shifted from open surgical stripping toward catheter-based endovenous techniques that are typically performed under local anesthesia in an outpatient setting.
