Radio Frequency Therapy

The principle of radiofrequency therapy (ClosureFast™ procedure) is based on the fact that the diseased veins (varicose veins) are heated and closed by a catheter with an integrated heating coil.

Remove varicose veins

At the Venenzentrum am See in Feldmeilen, we prefer to treat varicose veins with minimally invasive endovenous therapies. Compared to surgical procedures, they offer better results and higher patient satisfaction. We perform heat sclerotherapy by radiofrequency under local anesthesia, so that the treatment gives you as little pain as possible.

With over 3,000 procedures already performed with Medtronic ClosureFast™, Venenzentrum am See is a certified reference center. You are welcome to view our ClosureFast™ certificate.

  • minimal, painless surgery
  • little bleeding into the tissue
  • best possible cosmetic results

  • short treatment time
