The Expandable LeMaitre Valvulotome is designed to be used with a less invasive in situ bypass technique. It is the only self-sizing, self-centering valvulotome available. It cuts valves in the saphenous vein, a vein that runs from the groin to the knee. When used with a semi-closed technique, it helps to prevent wound complications. Valvulotomy can be performed without the need for angioscopy and without changing cutting heads during valve lysis.
