The invention concerns a vascular occlusion device. The invention is characterised in that it comprises two expandable members (3, 4) enabling it to be fixed by pressure on two portions of the vessel; it further comprises an intermediate part (5) deformable in twisting to an adjustable degree depending on the relative position of the two expandable members (3, 4); thereby producing a maximum constricted region (6) defining the extent of occlusion. The invention also concerns a apparatus for setting and a method for using such a device.
