This article explains, in educational terms, saphenous vein ablation — 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
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. 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. 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.
Saphenous Vein Ablation
The great and small saphenous veins are the most common sources of reflux, so ablation strategies frequently target these axial veins. Accurate ultrasound mapping of the sapheno-femoral or sapheno-popliteal junction guides where the catheter tip is positioned before energy or adhesive is delivered. Both thermal and non-thermal INVAMED devices can be applied to saphenous targets, with the choice guided by vein diameter and clinician judgment. Sealing the refluxing axial vein is intended to reduce the venous hypertension that drives symptoms and visible tributaries.
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. Because varicose disease reflects an ongoing tendency, follow-up and surveillance help detect new reflux early. Vein diameter, depth, and tortuosity influence whether a thermal or non-thermal device is more suitable.
Key Considerations
- Device figures cited by INVAMED describe studied performance and should not be read as individual guarantees.
- 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
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.
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.

Clinical and Technical Context
Fiber design matters: radial-emitting fibers distribute energy circumferentially around the vein wall, which is often associated with more uniform heating than older bare-tip fibers. 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. As with all venous treatments, the agent, concentration, and volume are selected by the clinician for the specific vein being treated. INVAMED's portfolio includes small-vein RF ablation needles and the VeinOFF treatment agent as adjuncts to its main ablation platforms. 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. The absence of thermal energy means nerve-injury risk associated with heat is generally reduced, though suitability still depends on individual anatomy. The main practical appeal is patient comfort during the procedure and avoidance of heat-related nerve irritation.
