Clarivein® is a minimally invasive, non‑thermal varicose vein treatment that combines mechanical agitation with a chemical sclerosant to close diseased veins. A doctor inserts a thin catheter under ultrasound guidance into the targeted vein, activates a rotating wire tip to gently disrupt the vein lining, and simultaneously delivers the sclerosant solution. The procedure takes about 30 minutes, requires only local numbing, and causes minimal discomfort or downtime.
