The invention relates to a device for the local extirpation of varicose veins to be inserted into a vein to be removed. The device (1) comprises a head part (2, 32, 52, 72, 92) comprising a main body provided with barbs (3, 33, 53, 73, 73', 93) and a guiding tip (8, 98, 78) facilitating the insertion of the device (1) into the vein, the barbs (3, 33, 53, 73, 73', 93) being oriented backwards relative to the direction of insertion of the device (1) so that the head part (2, 32, 52, 72, 92) can be inserted into said vein without being impeded by said barbs (3, 33, 53, 73, 73', 93), said barbs (3, 33, 53, 73, 73', 93) having a length and being at an angle relative to the longitudinal direction of the head part (2, 32, 52, 72, 92) in the operative position of the barbs (3, 33, 53, 73, 73', 93) which are sufficient to ensure that a vein, for which the device (1) is dimensioned, is gripped firmly by said barbs when said head is pulled out from said vein, a flexible actuating means (4, 34, 54, 74, 74', 94) being attached to said head.
