Abstract: A method of making a vascular occlusion device may include cutting a tubular member to form an expandable frame including a first hub integrally formed with the expandable frame adjacent a first end of the expandable frame, and a plurality of longitudinally-oriented struts extending in a direction opposite the first end; heat-setting the expandable frame to define an expanded configuration of the expandable frame; sliding a constrainment member over the plurality of longitudinally-oriented struts, the constrainment member being formed using additive manufacturing technology; fixedly securing the constrainment member to the plurality of longitudinally-oriented struts to define a second hub of the expandable frame; and cutting the plurality of longitudinally-oriented struts adjacent the constrainment member and opposite the first end relative to the constrainment member.
