1. An occluding device for occlusion of fluid flow through a lumen of a body vessel having a vessel wall, the device comprising:

  • an expandable tubular body having a tubular wall defining a lumen formed therethrough, the tubular wall having a proximal end extending to a distal end along a longitudinal axis of the tubular body, the tubular body including a plurality of longitudinal slits formed through the tubular wall to define a plurality of flexible strips bound by a proximal non-slit portion at the proximal end and a distal non-slit portion at the distal end, the tubular body including a plurality of barbs disposed on the flexible strips, the tubular body being configured to move between a collapsed state and an expanded state, the tubular body being configured to open radially to engage the barbs with the vessel wall defining the expanded state and to collapse along the longitudinal axis to draw the vessel wall radially inward defining the collapsed state;

    occluding material housed within the lumen of the tubular body, wherein the occluding material is configured to move between a collapsed state and an expanded state with the tubular body; and

    an expander to expand the tubular body, the expander comprising an elongate member disposed within the lumen of the tubular body and through the occluding material, the elongate member having a distal portion attached to the distal non-slit portion of the tubular body extending to a proximal portion configured to engage with the proximal non-slit portion of the tubular body to adjust the axial distance between the proximal and distal ends of the tubular body and move the device from the collapsed state to the expanded state wherein the elongate member is a resorbable suture having a plurality of flexible expandable tabs at the proximal portion.
