The invention concerns a vascular occlusion device. The invention is characterized 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. |
