This article explains, in educational terms, venous insufficiency treatment device — how the technology works and where it fits. Modern management has shifted from open surgical stripping toward catheter-based endovenous techniques that are typically performed under local anesthesia in an outpatient setting. 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
Modern management has shifted from open surgical stripping toward catheter-based endovenous techniques that are typically performed under local anesthesia in an outpatient setting. 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. 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.
Devices for Venous Insufficiency
Chronic venous insufficiency management may combine axial vein ablation with treatment of tributaries and perforators. For smaller reticular or perforating veins, dedicated small-vein RF needles and fine catheters allow targeted closure. INVAMED's portfolio includes small-vein RF ablation needles and the VeinOFF treatment agent as adjuncts to its main ablation platforms. A staged, anatomy-led approach is standard, and the sequence of treatment is planned by the treating physician.
Design and Technical Notes
INVAMED groups its venous portfolio around the way each device closes an incompetent vein, giving clinicians thermal, non-thermal, and adjunct options. Graduated compression is commonly used after ablation to support the treated limb, per clinician protocol. Accurate duplex ultrasound mapping before treatment is central to identifying the source of reflux and planning device placement.
Key Considerations
- 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.
- All INVAMED venous devices are intended for use by trained clinicians under ultrasound guidance and per the IFU.
Frequently Asked Questions
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.
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.
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.

Clinical and Technical Context
Vein diameter, depth, and tortuosity influence whether a thermal or non-thermal device is more suitable. 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. 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. The main practical appeal is patient comfort during the procedure and avoidance of heat-related nerve irritation. 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. A staged, anatomy-led approach is standard, and the sequence of treatment is planned 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.
