Find relief from venous reflux disease with the ClosureFast™ Procedure.

ClosureFast Procedure

ClosureFast System

The ClosureFast procedure uses controlled and consistent heat to close the diseased vein to provide:

  • Consistent and controlled treatment
  • Proven outcomes with rapid recovery1
  • A positive patient experience1


The ClosureFast procedure is performed on an outpatient basis.

  • Using ultrasound, your physician will position the catheter into the diseased vein through a small opening in the skin.
  • The small catheter delivers heat to the vein wall, causing it to shrink and the vein to seal closed.
  • Once the diseased vein is closed, blood will reroute itself to other healthy veins.
Closurefast Procedure

Following the procedure, a simple bandage is placed over the insertion site, and additional compression may be provided to aid healing. 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

Over 2 million patients have been treated with the ClosureFast procedure in over 100 countries around the world.

Venous Reflux Disease:

  • Relief of symptoms after two days with a noticeable improvement in one to two weeks
  • Less pain than laser – an outpatient procedure with local or general anesthesia2
  • Proven results with positive patient outcomes and experience2,3
  • Rapid recovery – on average patients resume normal activities within a few days1


Improved Clinical Outcomes Compared to Compression Therapy Alone

  • A prospective study has shown that 76% of ulcers were healed within 6 months after the ClosureFast or ClosureRFS procedure.4
  • In a separate study, 95% of ulcers remained healed at 18 months.5

Individual results may vary.

NOTE: These patients were treated with the ClosureFast procedure and maintained compression.
