Covidien ClosureRFG™ Radiofrequency Generator

Radiofrequency Generator for Venefit™ Targeted Endovenous Therapy

Covidien ClosureFast™ Radiofrequency Catheter

The ClosureRFG™ generator delivers radiofrequency (RF) energy to the Covidien ClosureFast™ Endovenous Radiofrequency Ablation (RFA) Catheter, enabling controlled vein lumen contraction for a fast and effective treatment of Chronic Venous Insufficiency (CVI). Temperature and power are continuously monitored for optimal performance.

The generator can also be used with the Covidien ClosureFast™ 3cm Endovenous Radiofrequency Ablation (RFA) Catheter and the Covidien ClosureRFS™ Endovenous Radiofrequency Stylet, providing continuous procedural feedback during the treatment of short refluxing vein segments and refluxing perforator veins.

This device has been specifically engineered with the end user in mind. A simple and intuitive user interface, combined with a large color screen and optimized internal software, makes the Venefit™ procedure faster and easier to use.

What are Varicose Veins

Mission Surgical Varicose Veins

Varicose veins are enlarged veins that can be blue, red or flesh colored. They are often raised above the skin on legs and look like twisted bulging cords. Varicose veins occur when the valves in the veins that carry blood from the legs toward the heart no longer function, causing blood to pool in the legs.






What is Chronic Venus Insufficiency (CVI)

Varicose Veins

Chronic Venous Insufficiency (CVI) is a progressive medical condition that worsens over time and affects the veins and vessels in the leg that carry oxygen-poor blood back toward the heart. Varicose veins, which are enlarged veins in the leg that appear like twisted, bulging cords, can progress to CVI if left untreated.

There are a number of factors that contribute to varicose veins and CVI, including pregnancy and heredity. As varicose veins progress to become CVI, other painful and symptoms like leg swelling, skin damage and ulcers may occur.1,2


Minimally Invasive Treatments

Today, there are a number of minimally invasive treatment options for CVI sufferers. While treatments like compression stockings are often first prescribed to manage symptoms, there are a variety of treatments that can actually treat the diseased veins to eliminate varicose veins, improve your quality of life and halt the progression of CVI.3


Endovenous Ablation

Endovenous thermal ablation is a minimally invasive treatment that involves the insertion of a thin, flexible tube called a catheter into a diseased vein to seal it shut using heat. Blood that would normally return toward the heart through these veins will then travel through other veins instead. Over time the treated vein shrinks and is absorbed by the body. Compared with surgical options like ligation and vein stripping, endovenous ablation results in less pain and quicker recovery time.4


Venefit™ Targeted Endovenous Therapy

The Venefit™ procedure is the only minimally invasive segmental radiofrequency (RF) ablation treatment that utilizes radiofrequency energy to provide an even and uniform heat to contract the collagen in the vein walls, causing them to collapse and seal. Once a leg vein is closed, blood flow is redirected to healthy veins.

The Venefit procedure allows for a quick, comfortable recovery and a return to everyday activities, while also improving the appearance of varicose veins3,4.
