Device for destroying varicose veins of the lower limbs in man. It consists of a tube (1) which is open at both ends and which we will refer to as the cylinder, the latter having on the outer part of one of its ends a dozen or so small roughened areas (3) each of approximately half a millimetre. A solid rod (2) slides easily in the cylinder and will be referred to as the plunger. One of the ends of this plunger is continued via a nylon thread (4) on which there is a ball-shaped bulge (5). The small roughened areas are intended to destroy the inner part of the vein, called the epithelium or intima. Inside the cylinder, the part left free by the nylon thread will be filled by a sclerosing liquid intended to destroy the varicose vein. The device according to the invention is intended in particular for destroying varicose veins of the lower limbs in man. <IMAGE>
