VenaBLOCK® offers a distinct approach to managing venous insufficiency by delivering cyanoacrylate adhesive directly into the diseased vein segment (e.g., great saphenous vein, small saphenous vein, or perforator veins). Through a continuous application of the adhesive under controlled pressure over the target vessel segment, VenaBLOCK® aims to close the dysfunctional vein with minimal invasiveness and rapid procedure times.
Cyanoacrylate Closure Mechanism
Permanent Vein Closure: Injecting cyanoacrylate into the incompetent vein produces a stable polymer seal, reducing reliance on thermal ablation or surgical ligation.
Targeted Delivery: Provides immediate and durable adhesion, with typically minimal post-procedure discomfort.
Dual-Lumen Catheter System
0.5 mm internal diameter (ID) for cyanoacrylate injection.
0.9 mm ID for laser or other adjunct therapy, if required.
Versatile Applications: Catheter design accommodates both adhesive infusion and laser guidance (or other device) in a single session, facilitating multi-modal intervention.
Laser-Guided Catheter Shaft
Braided Reinforcement: Incorporates a PTFE-lined interior with an outer braided 4F–6F-diameter shaft for structural stability.
Marked Every 2 cm: The 100 cm catheter includes 2 cm markings, aiding consistent depth control and precise adhesive placement.
Minimally Invasive Delivery
Advanced Tip & Pressure: By coordinating continuous cyanoacrylate delivery and external vein compression, the solution spreads evenly along the vein’s interior, ensuring uniform closure.
Reduced Thermal or Surgical Stress: Minimizes patient discomfort and accelerates post-procedure recovery compared to conventional stripping or thermal ablation methods.
