An occlusion device has spaced struts connected by end members and is covered with a sheath. An actuator runs through the frame defined by the struts and end members. The struts are delivered in tension and allowed to relax to flex outwardly for fixation. The struts can also be placed in a relaxed condition and then flexed with relative movement of the end members when coming closer together. The set position of the struts is locked. The actuator can be at least in part removed after the struts flex. An anchor can be placed proximally to the frame and it contains spaced elongated members connected into a tubular shape with circumferential bands that have bends for flexibility to collapse for insertion and expand when placed in the lumen.
