It is possible to break free from varicose veins and the leg pain that comes with it. Treating vein disease with Medtronic procedures is easier than you may think. As always, your doctor will help you understand the care journey that’s best for you.

Medtronic offers two vein disease treatments.

Talk with your doctor about finding lasting relief for leg vein disease and varicose veins with both of our minimally invasive therapies, performed on a same-day outpatient basis.

VenaSeal closure system components on white background

VenaSeal procedure

The VenaSeal procedure delivers a small amount of a specially formulated medical adhesive to seal — or close — the diseased vein, rerouting blood to nearby healthy veins, which provides symptom relief.

Treatment method
VenaSeal treatment is a simple procedure performed by your doctor that is designed to close diseased veins with a medical adhesive delivered through a small catheter.

Procedure experience
This is a 30- to 60-minute outpatient procedure that can be performed on both legs with minimal pain and requires no tumescent anesthesia.

Recovery expectations
Typically, patients return to normal activity on the same day as their procedure.

ClosureFast radiofrequency ablation system on white background

ClosureFast procedure

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

Treatment method
ClosureFast treatment is a minimally invasive procedure performed by your doctor using thermal energy delivered through a small catheter to shrink and cut off blood to the diseased vein.

Procedure experience
This is a 30- to 60-minute outpatient procedure performed on one leg per appointment, with local anesthesia along the leg and minimal pain.

Recovery expectations
On average, patients resume normal activities within a few days.1

Quick relief and recovery

Everyone recovers differently depending on their particular condition and treatment type, but typical recovery from leg vein treatment is quick.

What to expect with the VenaSeal procedure

Symptoms are caused by the diseased vein. That means symptoms may improve as soon as the diseased vein is closed. The nonthermal VenaSeal procedure is designed to reduce recovery time compared to thermal treatments. Many patients return to normal activity immediately after the procedure. Your doctor can help you determine when you can return to normal activity.

Possible complications of the VenaSeal procedure may include allergic reaction, inflammation, phlebitis, deep vein thrombosis, and/or pulmonary embolism. Talk to your doctor about the risks and benefits.

What to expect with the ClosureFast procedure

Most patients report relief of symptoms after two days, with a noticeable improvement in one to two weeks. Patients treated with the ClosureFast procedure may resume normal activities more quickly than patients who undergo surgical vein stripping or laser ablation. With the ClosureFast procedure, the average patient typically resumes normal activities within a few days.1 For a few weeks following the treatment, your vein specialist may recommend a regular walking regimen and suggest you refrain from strenuous activities (heavy lifting, for example) or prolonged periods of standing.

Possible complications of the ClosureFast procedure may include nerve injury, hematoma, phlebitis, thrombosis, and/or pulmonary embolism. Talk to your doctor about the risks and benefits.
