ClosureFast Procedure

About

The ClosureFast procedure uses radiofrequency energy or heat to close the diseased vein, which redirects blood flow to healthy veins, relieving symptoms.

Step 1: Thermal catheter is placed

Using an ultrasound, your physician will position the catheter into the diseased vein through a small access site.

Step 2: Local anesthetic is applied

A series of injections numbs the area around the vein.

Step 3: Heat is delivered to vein wall

The vein wall is heated and the catheter is withdrawn from the vein.

Step 4: Vein is closed

The vein is “heat sealed” as the catheter is removed. A multilayer compression wrap is applied from foot to groin.

Before the procedure

You will have an ultrasound imaging exam of the leg being treated. This exam is important for assessing the diseased superficial vein and planning the procedure.

During the procedure

Your doctor will discuss the procedure with you. Here is a brief summary of what to expect:

The ClosureFast procedure is performed on an outpatient basis. Your doctor will perform the ClosureFast procedure. Using an ultrasound, your doctor will position a catheter in the diseased vein through a small opening in the skin.
The small catheter delivers heat to the vein wall, causing it to shrink and seal the vein. Once the diseased vein is closed, blood will reroute itself to other healthy veins.

After the procedure

You will be taken to the recovery area to rest.
Following the procedure, your doctor will apply a simple bandage over the insertion site and will give you compression stockings to aid in the healing process. Your doctor may encourage you to walk and to refrain from extended standing and strenuous activities for a period of time. The average patient typically resumes normal activities within a few days.^1,2
Your doctor will recommend follow-up care as needed.

Benefits of the ClosureFast procedure

Relief of symptoms after two days, with a noticeable improvement in one to two weeks³
Minimally invasive outpatient procedure
Less pain and bruising than laser treatment³
Faster recovery than laser treatment³
³Proven results with positive patient experience^1,3,4

Rapid recovery — on average, patients resume normal activities within a few days²
Lasting results — the only radiofrequency energy procedure with published long-term clinical data demonstrating safety and efficacy, with a 91.9% closure rate at five years.⁴
