The ClariVein ® procedure works by treating the affected veins internally through a very small incision that is usually made on the upper thigh area. During the procedure, your vein specialist will insert a medical catheter with a rotating fiber on its end into the vein.
Once the device reaches the damaged vein, the fiber begins to rotate. As the fiber rotates, it carefully removes the lining of the damaged vein, while also delivering a medical solution to treat the underlying cause.
The catheter will continue to rotate for several minutes, and there may be a light humming sensation near the affected area, but it should not cause any major pain or discomfort.
