Clarivein is a local anaesthetic treatment for varicose veins. It only needs one small pin hole per vein treated. It is also called MOCA (Mechanochemical Ablation). Unlike laser and radiofrequency, Clarivein only needs one local anaesthetic injection per vein treated. There is no heat used and so no risk of getting burns to skin or nerves.

Clarivein is based on a wire that rotates inside the vein, and sclerotherapy solution that then closes the damaged vein. The whole process is performed under ultrasound control. Prize winning research from The Whiteley Clinic showed how the combination of the rotating wire and the sclerotherapy cause the permanent destruction of the vein (Bronze award at the ACP, Phoenix 2014). In addition, the research team at The Whiteley Clinic and University of Surrey published a paper showing how the system worked with different combinations of treatment.
