ANDOVER, Mass., March 25 -- Diomed Holdings Inc., of Andover, has been given approval from Health Canada for its EndoVenous Laser Treatment (EVLT) laser system to treat varicose veins. Diomed also announced it has engaged Sigmacon Health Products Corp. of Toronto, Ontario, as its exclusive Canadian distributor for the sale of EVLT lasers and EVLT optical fiber kits to physicians who treat varicose veins. Diomed has already received approval by the US Food and Drug Administration "for treatment of varicose veins and varicosities associated with the superficial vein reflux of the greater saphenous vein." According to the company, EVLT is a nonsurgical treatment that can be performed under local anesthetic in a doctor’s office to treat the medical cause of varicose veins at its source. "Thousands of US patients have benefited from EVLT by being able to walk out of their physician's office and resume normal activity quickly without any lasting side effects," said James A. Wylie Jr., president and CEO of Diomed. "Canadian approval of EVLT is both a milestone for Diomed and an important validation of EVLT in the treatment of varicose veins."
