This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating varicose vein devices. 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. 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. 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.
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
- Vein diameter, depth, and tortuosity influence whether a thermal or non-thermal device is more suitable.
- Because varicose disease reflects an ongoing tendency, follow-up and surveillance help detect new reflux early.
- Device figures cited by INVAMED describe studied performance and should not be read as individual guarantees.
Frequently Asked Questions
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.
Who decides which vein treatment is appropriate?
Only a qualified clinician can decide, based on ultrasound mapping and individual assessment; this article is educational and not a treatment recommendation.
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).
About INVAMED
INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development. INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005.
Clinical and Technical Context
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. 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. Both thermal and non-thermal INVAMED devices can be applied to saphenous targets, with the choice guided by vein diameter and clinician judgment. 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. Accurate duplex ultrasound mapping before treatment is central to identifying the source of reflux and planning device placement. A staged, anatomy-led approach is standard, and the sequence of treatment is planned by the treating physician. Device figures cited by INVAMED describe studied performance and should not be read as individual guarantees. Graduated compression is commonly used after ablation to support the treated limb, per clinician protocol.
