Radio frequency methode

Minimal-invasive therapy methods with high-frequened electrical energy have been tested since the 1980s. In the radio frequency therapy, a thin catheter is used, which is heated up through radiowaves , which affects the inner side of the vein and causes the diseased vein to close up. The creation of heat is caused by radiofrequency instead of ClosureFast or laserlight.

The practitioner inserts the flexible catheter into the leg, with the help of an ultrasound image, up to the groin or knee. When having reached the affected vein, heat is emited in a controlled way and by pulling back, the inner wall of the vein is heated up, which causes the vein to close up. This stops the unhealthy backflow of blood. In the weeks and months following the treatment, the body breaks down the closed up vein.
