Vein disease treatments
Minimally invasive thermal treatment for vein disease and varicose veins.
The ClosureFast procedure uses radiofrequency energy or heat to close the diseased vein, which redirects blood flow to healthy veins, relieving symptoms.
Using an ultrasound, your physician will position the catheter into the diseased vein through a small access site.
A series of injections numbs the area around the vein.
The vein wall is heated and the catheter is withdrawn from the vein.
The vein is “heat sealed” as the catheter is removed. A multilayer compression wrap is applied from foot to groin.
Having this procedure made such a difference in my life and my general wellbeing. Thank you for not only making lifesaving therapies, but also focusing on procedures that better people’s lives and help them live the most normal, comfortable life they can.

Individual results may vary, talk to your doctor for more information.
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.
Your doctor will discuss the procedure with you. Here is a brief summary of what to expect:

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.
Type of therapy
Thermal shrinkage of the vein wall with radiofrequency energy or heat
Inpatient or outpatient procedure
Outpatient procedure
One- versus two-leg treatment
Typically, each leg will be treated in separate appointments
Needle sticks required
One needle stick for vein access. Typically, 5 to 10 needle sticks for anesthesia.
Typical post-treatment recovery
Healing of vein access site, anesthetic needle stick sites, and also healing of ablated vein section
Compression hose
Required for approximately one week
Procedure success rate
91.9% after five years4
Most patients report feeling little, if any, pain during the ClosureFast procedure.3 Your doctor will give you a local or regional anesthetic to numb the treatment area.
