The LaserBLOCK Varicose Vein Laser System is an INVAMED endovenous laser platform engineered for endovenous laser ablation (EVLA) of incompetent superficial veins, including the great saphenous vein (GSV) and small saphenous vein (SSV). It is designed to deliver targeted thermal energy through a specialized fiber, giving physicians a minimally invasive tool for treating venous reflux.
What Is the LaserBLOCK System Designed to Do?
LaserBLOCK is intended to deliver laser energy through a fiber introduced percutaneously into an incompetent vein segment. As the fiber is withdrawn, controlled thermal energy is applied along the vein wall, which is intended to cause vein wall contraction and closure.
This approach is designed to reduce reliance on extensive incisions associated with traditional vein stripping, while giving the treating physician direct control over fiber placement and energy delivery under ultrasound guidance.
What Wavelength and Fiber Options Does LaserBLOCK Offer?
According to INVAMED's product documentation, the LaserBLOCK system is available in variants covering multiple wavelengths, including 810 nm, 940 nm, 980 nm, and 1470 nm, depending on the configuration selected. Fiber types include bare-tip, radial-tip, and jacketed single-use fibers, with fiber diameters generally ranging from approximately 400–600 µm for bare fibers up to roughly 600–800 µm for radial fibers.
The availability of multiple wavelength and fiber configurations is intended to give physicians flexibility when tailoring energy delivery to vein diameter and anatomical variation.
What Design Features Characterize LaserBLOCK?
Key design characteristics highlighted by INVAMED include:
- Optimized fiber technology — high-purity fiber construction in radial or bare-tipped configurations, intended to promote even energy distribution along the vein wall
- Minimally invasive delivery — percutaneous fiber introduction through a small access point rather than open incisions
- Ultrasound compatibility — designed for use alongside real-time ultrasound guidance so physicians can track fiber position and vein response
- Versatile clinical application — intended for GSV, SSV, and other superficial veins where reflux contributes to varicose vein formation
What Are the Noted Contraindications?
INVAMED's product documentation lists several situations physicians should consider before using LaserBLOCK, including veins that are too tortuous or large for effective fiber navigation, active infection in the target area, and patient comorbidities that preclude tumescent anesthesia or standard endovenous procedures. As with any endovenous device, patient selection and suitability are determined by the treating physician.
Frequently Asked Questions
What vein conditions is LaserBLOCK intended for?
LaserBLOCK is intended for endovenous laser ablation of incompetent superficial veins, such as the great saphenous vein and small saphenous vein, where venous reflux contributes to varicose vein formation.
What about regulatory status and availability?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Does LaserBLOCK require ultrasound guidance?
The system is typically used alongside ultrasound guidance so physicians can visualize the fiber position and monitor the vein's response throughout the procedure.
