Varicose Veins Treatment


The Canasi Medical Institute uses the Venefit™ procedure (formerly called VNUS Closure™), or endogenous radio frequency ablation, to treat vein disease. We have chosen this procedure because it is clinically proven to be an effective means of treating varicose veins and their underlying cause, venous reflux. It is a minimally invasive procedure with less pain and less bruising compared to traditional vein stripping surgery and laser treatment. Using the Venefit™ system, physicians close the diseased or damaged vein. This is done by inserting a catheter into a vein and heating the vein wall using temperature-controlled radio-frequency energy. Heating the vein wall causes collagen in the wall to shrink and the vein to close. After the vein is sealed shut, blood naturally reroutes to healthy veins and the body dissolves the closed vein over time. The procedure is done in the office, takes about 15 minutes, and patients walk away from the procedure and typically return to their normal activities within a day. Venefit™ uses two types of instruments to close the vein, the ClosureFAST™ Catheter and the ClosureRFS™ Stylet. The Canasi Medical Center will determine which is right for each patient based on the type of vein disease you have. 

Venefit™ using the ClosureFAST Catheter

The Venefit™ procedure is the newest procedure for treating superficial veins with venous reflux disease. Venefit™ uses The ClosureFAST™ catheter with either a 6.5 cm or 3 cm electrode to generate radiofrequency waves to heat and collapse the vein wall. The catheter is used to close the greater saphenous vein, lesser saphenous vein or the shorter access branches off these veins.

Venefit™ using the CLOSURE RFS Stylet Perforator veins are those that connect the deep venous system with the superficial venous system. When the perforator veins need to be treated, the ClosureRFS™ Stylet is used to close the vein. This is the only intravascular ablation device specifically cleared by the FDA for the treatment of incompetent perforator veins. This minimally invasive outpatient treatment can be either the primary procedure or in addition to saphenous vein ablation with ClosureFAST™ catheter.

Perforating Veins

Step 1

Catheter tip positioned 2cm distal to the saphenofemoral junction. Tumescent
fluid is administered.

Step 2

Catheter shaft allows fast and accurate
catheter re-positioning between treatment
cycles. No energy is delivered
during the re-positioning.

Step 3

7cm vein segment treated all at once
during 20-second treatment cycle.
Additional vein segment treated serially.

Step 4

This treatment of 45cm vein
takes three to five minutes
(seven treatment segments).

Frequently Asked Questions

What is superficial venous reflux?

Superficial venous reflux is a condition that develops when the valves that usually keep blood flowing out of your legs become damaged or diseased. This causes blood to pool in your legs. Common symptoms of superficial venous reflux include pain, swelling, leg heaviness and fatigue, as well as varicose veins in your legs

Is the Closure procedure painful?

Patients report feeling little, if any pain during and after the procedure.

How soon will my symptoms improve?

Many patients notice an immediate relief of symptoms like pain, leg heaviness and fatigue. The full benefits of the proceeder make take 1-2 weeks.

How is the Closure procedure different from vein stripping?

During a stripping procedure, incisions are made in your groin and ties off the vein, after which a stripper tool is threaded through the saphenous vein and used to pull the vein out of your leg through a second incision just above your calf. In the Closure procedure, there is no need for groin surgery. Instead, the vein remains in place and is closed using a special (Closure) catheter inserted through a small puncture. This may eliminate the bruising and pain often associated with vein stripping.

How quickly after treatment can I return to normal activities?

Many patients typically return to normal activities within a day. For a few weeks following the treatment, Dr. Canasi may recommend a regular walking regimen and suggest you refrain from very strenuous activities.

How soon after treatment will my symptoms improve?

Most patients report a noticeable improvement in their symptoms within one to two weeks following the procedure.

Is there any scarring, bruising, or swelling after the Closure procedure?

Patients report minimal to no scarring, bruising or swelling following the Closure procedure.

Is the Closure treatment covered by my insurance?

Many insurance companies are paying for the Closure procedure in part or in full. Most insurance companies determine coverage for all treatments, including the Closure procedure, based on medical necessity. Your physician can discuss your insurance coverage further at the time of consultation.
