The 3M? AbThera? Advance Open Abdomen Dressing is a temporary abdominal closure device that helps surgeons take control early when managing a challenging open abdomen, helping to achieve primary fascial closure. The AbThera Advance Dressing features a perforated foam that collapses medially helping facilitate primary fascial closure by providing medial tension on the wound edges when negative pressure is applied.
