Venaseal Closure System

Healthy leg veins contain valves that open and close in a coordinated way to get blood back up to the heart, as part of a proper circulatory function. Damage or disease in these valves can lead to a variety of problems, like varicose veins, which affects 30 million Americans.

Varicose veins can be painful and may indicate a more serious condition: venous reflux disease, also known as chronic venous insufficiency (CVI). The chief characteristic of this condition is that the valves in the legs become damaged or diseased.

When venous reflux disease is left untreated, vein valves eventually do not close properly. This is what can cause varicose veins and a number of other problems:

• Leg pain, cramping
• Leg or ankle swelling
• Leg heaviness or fatigue
• Skin changes
• Ulcers, sores, open wounds

It is essential to diagnose and treat problems with leg blood valves quickly, as valves that stop working cannot be repaired. Treatment generally involves closing or removing damaged veins and redirecting blood flow to healthy veins.

Traditional Versus Modern Treatment

Traditionally, varicose vein treatment involves heat to seal veins or surgical stripping of the damaged vein.

VenaSeal, a new procedure for varicose veins, uses an advanced medical adhesive to close diseased vein segments. It is the first and only treatment approved for use in the US that uses an adhesive of this nature.

The specially formulated adhesive is applied to the diseased vein using a catheter. The vein then becomes closed, and the blood is rerouted to nearby veins.

Heat-based treatments generally require anesthetics and carry with them the risk of burning or nerve injury. The nature of the VenaSeal system allows patients to more quickly resume normal activities and is a more comfortable procedure.

How It Works

How Successful Is It?

Clinical studies of VenaSeal show that it does, in fact, work well, with closure rates above 92 percent, even after a year.
