The VenaSeal™ closure system is the only non-tumescent, non-thermal, non-sclerosant procedure that uses a proprietary medical adhesive delivered endovenous method to close the vein. Thus eliminating the risk of injury to nerves while treating small veins, which is a risk occasionally associated with certain procedures. Clinical trials demonstrate that the procedure is not only safe but effective. The procedure is performed without the use of anesthesia, helping to avoid patient discomfort associated with multiple needles or injections.
