Non-Thermal Ablation

There are several treatment options that do not use heat for ablation. Each treatment method is uniquely designed for specific vein situations. And like thermal ablation treatments, patients can immediately return to normal activity with little or no pain.


Varithena® (polidocanol injectable foam) is an FDA approved prescription medicine injected into abnormal veins under ultrasound guidance to seal them shut. Some patients receiving Varithena® only need a single treatment. Additional treatment may be needed, depending on the number and size of veins to be treated.

Mechanochemical Ablation (MOCA)

ClariVein® is a treatment of venous insufficiency and like other endovenous procedures is aimed at closing down problematic veins. MOCA vein treatment uses the patented ClariVein® catheter and combines two methods of action: Mechanical agitation of the vessel by a rotating catheter tip with a sclerosant drug (chemical) sprayed from the tip of the catheter as it is pulled back. The agitation to the vein coupled with the medicine delivered to it, closes it down quickly.


The VenaSeal™ system is a form of ablation that improves blood flow by closing diseased veins with a medical adhesive (glue). A special catheter system delivers a small amount of a specially formulated adhesive to the diseased vein. The adhesive seals the vein and blood is rerouted through nearby healthy veins.

Currently this procedure is covered by some insurance providers.
