An occluding device is provided for occluding fluid flow through a lumen of a body vessel. The occluding device includes an expandable tubular body having a tubular wall defining a lumen formed therethrough. The tubular wall has a proximal end extending to a distal end along a longitudinal axis of the tubular body. A plurality of longitudinal slits is formed through the tubular wall to define a plurality of flexible strips bound by a proximal non-slit portion and a distal non-slit portion. A plurality of barbs is disposed on the flexible strips. The tubular body is configured to open radially to engage the barbs with the vessel wall defining an expanded state and to collapse along the longitudinal axis to draw the vessel wall radially inward defining a collapsed state. Occluding material is housed within the lumen of the tubular body and the occluding material is configured to move between a collapsed state and an expanded state with the tubular body.
