What to Expect
The ClosureFast™ procedure eliminates the need for groin surgery and general anesthesia, and is generally performed using local anesthesia in a vein specialist’s office or an outpatient surgical facility. The procedure takes approximately 45-60 minutes and most patients typically spend two to three hours at the medical facility due to normal pre- and post-treatment procedures.
Clinical Outcomes – Recovery Study
Studies show that the ClosureFast™ procedure is associated with lower rates of pain, bruising and complications and a faster improvement in patients’ quality of life when compared to 980 nm laser ablation.¹ The average patient typically resumes normal activities within a few days following treatment, and most patients report a noticeable improvement in their symptoms within 1-2 weeks after the ClosureFast™ procedure.²∗
ClosureFast™ Long-term Study with 5-year Follow-up
Demonstrated Long-term Effectiveness
In a large, multi-center, prospective trial, the ClosureFast™ procedure, delivered by the ClosureFast™ catheter, demonstrated the following results at 5 years.3,4
- 91.9% occlusion rate
- 94.9% reflux-free rate
Demonstrated Long-term Effectiveness
In over 200 patients across 8 centers, the ClosureFast™ procedure demonstrated the following high and long-lasting success rates:4♦
- CEAP (classification system): 74.1% showed an improvement
- Venous Clinical Severity Score (VCSS): Reduction in mean score from 3.9 to 0.9 (p < 0.05)
- Pain: Increase in percentage of patients free of pain from 41.1% to 98%
Consistent and Controlled
The ClosureFast™ catheter’s segmental approach eliminates the need for continuous pull-back of the energy source, allowing for controlled and repeatable radiofrequency ablation.
Optimal Therapeutic Power
Radiofrequency ablation delivers a lower heat gradient of energy at around 120°C. In contrast, some laser treatments can reach temperatures of over 700°C during the procedure.
Improved Patient Comfort
In a head-to-head post-procedure study, patients who received the ClosureFast™ procedure experienced less pain, less bruising and a faster recovery period than patients treated with 980 nm and 1470 nm laser ablation.1
Unlike vein stripping surgery or laser ablation, the catheter delivers heat in 20 second bursts to each vein segment. The ClosureFast™ procedure is commonly performed in an office or an outpatient setting, has been used to treat over 900,000 patients in 100 countries, and is covered by most health insurance plans in the United States and in several countries in Europe.
Therapy Comparison – Why Compromise?
Radiofrequency Ablation vs. Laser Ablation
As with all medical procedures, there is a chance that complications may occur, including, but not limited to the following:
- Vessel perforation
- Pulmonary embolism
- Adjacent nerve injury
- Skin burn or discoloration

* The ClosureFast™ Procedure is performed when medically necessary as diagnosed by a trained vein specialist. It is not designed to address spider veins or cosmetic issues. However, the successful treatment of varicose veins and CVI using the ClosureFast™ Procedure can produce cosmetic improvements. As with any medical procedure, you should consult your vein specialist and review all safety information prior to receiving treatment.
