VenaBlock offers a unique treatment for venous insufficiency. Treatment is simply delivering cyanoacrylate inside of disfunctioning vein segment.(VSM, VSP or perforator veins) continuously while applying pressure over target vein segments
A UNIQUE TREATMENT FOR VENOUS INSUFFICIENCY
CAN BE PERFORMED IN MINUTES
Physician only needs USG guidance to perform the procedure in outpatient conditions within several minutes. VenaBlock brings advantages such as eliminating tumescent anesthesia, ease of use, shortening of the procedure time and prevention from complications such as burn marks, bruising, hematoma, numbness and pigmentation in thermal ablation methods.
The VenaBLOCK closure system delivers immediate and lasting vein closure with its proprietary medical adhesive formula, with a demonstrated 94.6% closure rate at 3 years.
Total Amounts of VenaBlock Embolization Liquid Expected for Use in Vein Treatments
The amount of adhesive delivered is related to length of the target GSV. The VenaBlock Instructions for Use describe the application of 0.03 cc of the VenaBlock embolization liquid every cm in the target vein. The table below shows a calculation of the total expected amount of adhesive delivered as a function of target treatment length. Additional injections could be administered at sites of dilatation and junctions with tributaries. The exact application procedure and dosage is to be determined by the physician.

FEATURES
The VenaBLOCK closure system is indicated for use in closure of saphenous vein (vena saphena magna, valve saphenous parva) or perforator veins in endovenous treatment of incompetent varicose veins.VenaBlock is a n-BCA-polymer structure of which was changed by adding a monomer synthesized by the producing company. It is a ready for use, blue colored, transparent liquid. Product show polymerization effect with embolization. When contacted with living tissue and in humid environments, it very fast becomes polymerized by forming a thin, flexible membrane with high tension resistance that ensure sticking firmly to the tissues. The subject matter membrane ensures natural fit with the structure of the tissues, it is watertight, does not effects the structures of the blood and organic liquids. This formed membrane, since the polymerization of the product does not cause occurrence of glassy components, it can easily be perforated with surgical needle after it is hardened. The polymerization time changes according to the type of tissue polymer contacted, characteristics of the liquid found, and amount of the product used. When it is applied in the right conditions, VenaBlock starts polymerization after 1-2 seconds and finish the polymerization process in about 5 seconds.
POTENTIAL ADVERSE EFFECTS
Below is a list of the potential adverse effects (e.g., complications) associated with the use of the VenaBlock system. The adverse events associated with the device are similar to those with traditional endovenous thermal ablation procedures.
