1. An apparatus for treating a wound with negative pressure wound therapy, comprising:
an elliptical stabilizing structure comprising a plurality of cells and configured for insertion into or over a wound, the stabilizing structure configured to collapse under negative pressure by collapsing one or more cells, each cell defined by one or more walls forming a closed perimeter and having a top end and a bottom end with an opening extending through the top and bottom ends, and wherein one or more cells located along a central transverse axis of the stabilizing structure are larger than one or more cells located closer to a longitudinal axis edge of the stabilizing structure; and
wherein one or more cells located near the center of the stabilizing structure are smaller than one or more cells closer to a horizontal axis edge of the stabilizing structure.
