VenaBLOCK Non-Thermal Treatment for Vein Disease & Varicose Veins

A cyanoacrylate-based vein closure system for superficial venous incompetence, delivering non-thermal occlusion with minimal local anesthesia and fast post-procedure recovery.

VenaBlock™—often referred to internationally as “Turkish Glue”—is an innovative, minimally invasive solution for varicose vein management. By leveraging a unique cyanoacrylate-modified polymer that rapidly polymerizes in under one second, VenaBlock seals the insufficient vein segment with remarkable efficiency and negligible risk of embolic complications. Clinical publications report a success rate of around 96%, making VenaBlock a breakthrough in modern venous ablation therapy.

Ultra-Fast Polymerization

The cyanoacrylate-based polymer reaches full set in <1 second, enabling precise vein closure with minimal risk of distal embolization.

A red laser (630 nm) is integrated into the catheter shaft to improve visibility and tracking under procedural imaging. This feature dramatically streamlines catheter navigation through tortuous venous segments.

Thanks to superior kink resistance and radial-tip design, VenaBlock can be advanced through curved varicose veins without a dedicated guidewire, reducing procedural complexity.

The procedure typically completes within a short timeframe. In many cases, applying 1-second compressions every ~10 cm along the target vein is sufficient to achieve rapid sealing.

Constructed with a PTFE Teflon-braided catheter shaft (6F, 5F, or 4F options), it remains flexible yet strong, navigating tortuous veins without risk of collapse or excessive friction.

The catheter can safely ablate varicose veins within 0.5 cm of the saphenofemoral junction (SFJ). By controlling venous closure so close to the SFJ, VenaBlock effectively reduces the risk of incomplete occlusion or recurrences.

With under-one-second polymerization near the SFJ, any significant risk of embolization is significantly minimized—a cornerstone for patient safety.

Minimally Invasive

Allows outpatient procedures with local anesthesia, minimal post-procedural pain, and quick return to daily activities.

The radial-tip design and kink-resistant shaft help traverse tortuous veins without a guidewire.

Ultra-fast polymerization means reliable occlusion from the SFJ downward, minimizing recanalization.

Rapid set time (<1 second) near SFJ drastically limits potential embolic events.

Eliminates the thermal pain associated with lasers or radiofrequency devices, while still ensuring high efficacy.
