ClariVein Technique for Treating Varicose Veins

For 350 years, varicose veins have been treated with a surgical technique. In the past 10 years, laser and radiofrequency have taken over. Now there’s MOCA™ varicose vein treatment using the ClariVein catheter. This is the future of varicose vein treatment – ask your physician about it!

Benefits of ClariVein

MOCA™ varicose vein treatment using the ClariVein catheter has advantages over existing techniques including:

  • Effective and safe technique with no pain
  • Minimal discomfort & negligible bruising
  • No risk of thermal (heat) damage as there would be from techniques such as laser or radio frequency ablation
  • No risk of nerve or skin damage
  • No multiple needle stick injuries (no tumescent anesthetic is required)
  • No internal leg pressure
  • Rapid return to normal activities

Compared to other similar techniques (laser or radiofrequency), there are greatly reduced pain levels, discomfort and bruising during and post-procedure. This is due to the way that ClariVein works—it disrupts the lining of the vein (the endothelia), allowing the highly effective use of a drug, which is used to close the vein.

Thermal techniques such as laser or radiofrequency use heat to destroy the vein and, as a result, can cause trauma and, hence, much of the pain and bruising associated with these techniques.

During a ClariVein procedure, the patient should feel a “buzzing” in their leg, which is not painful. There is also a quick return to normal activities.

Zero Risk of Thermal Injury

ClariVein generates no heat, therefore there is no risk of thermal injury—a risk that can occur with other techniques. As a result, there is no risk of nerve injury with ClariVein.

No Need for Tumescent Anesthetic

The lack of heat during a ClariVein procedure means there is no need for the use of tumescent anesthetic. This is an uncomfortable and often painful part of the procedure due to multiple needle stick injuries and the internal pressure of the anesthetic on the leg (usually between 250ml and 400ml of fluid are pumped into the leg, causing it to swell).

With lasers and radiofrequency, tumescent anesthetic is an essential part of the procedure as it prevents heat entering the body and causing thermal injury. With ClariVein, this is not needed.

Clinical Results with ClariVein

While there currently are not any long term data on the effectiveness of the ClariVein technique, there is one year data available, which is at least as good as what was available for both laser and radiofrequency at the same point. All the indications are that ClariVein will provide a safe, effective and lasting technique for the treatment of varicose veins.

ClariVein is FDA approved and CE marked.
