The VenaSeal closure system is the only non-thermal, non-tumescent, non-sclerosant procedure approved for use in the U.S. that uses a specially formulated medical adhesive that closes the diseased vein. The VenaSealclosure system treats symptomatic venous reflux disease in the lower extremity superficial veins, often the underlying cause of painful varicose veins. During the procedure, the medical adhesive is inserted into the VenaSeal closure system’s dispensing gun that is attached to a catheter. The catheter is advanced into the diseased vein under ultrasound guidance and the medical adhesive delivered precisely to the treatment area which is then briefly compressed. This closure system procedure is designed to minimize patient discomfort and reduce recovery time. After the procedure, a small bandage will be placed at the access site. Patients are able to rapidly return to normal activities.
