The invention is directed to a method of non-invasively treating a varicose vein (), for example the Great saphenous vein (GSV), wherein the vein or the vein system to be treated is divided into sections () with a length () separated by a spacing (s). The sections can be pre-defined before the treatment, for example to target a junction () to a tributary (), or with respect to the sapheno-femoral junction (), and can vary in length and location, for example to avoid a sensitive structure () such as nerves.

Method and device for treating varicose veins by application of high-intensity focused ultrasound

A method of localizing and preferably visualizing a vein within a limb, preferably within a leg, of a patient, with an imaging device. The method includes the following steps of: fully or partially collapsing at least a segment of the vein to be localized at a collapsing site during a collapsing step; inducing blood flow within the vein at the collapsing site, while the segment of the vein is fully or partially collapsed, during a pumping step; and visualizing the collapsing site with the imaging device in an imaging step, at least during the pumping step.
