Wound closure devices

An apparatus for treating a wound with negative pressure wound therapy, the apparatus comprising:

• a stabilizing structure for insertion into a wound, the stabilizing structure comprising:
• a length corresponding to a y-direction and extending along a central longitudinal axis of the stabilizing structure between a first end and a second end of the stabilizing structure;
• a width corresponding to an x-direction, the width being transverse to the length and extending along a central transverse axis of the stabilizing structure between a first side and a second side of the stabilizing structure;
• and
• a height corresponding to a z-direction, the height being transverse to the length and the width and extending between a top surface and a bottom surface of the stabilizing structure;
• wherein the length and width are each greater than the height;
• wherein the stabilizing structure comprises a plurality of cells defined by one or more walls, the cells being provided side-by-side in a horizontal plane parallel to the x-direction and the y-direction, wherein each of the cells has a top end and a bottom end with an opening extending through the top and bottom ends in the z-direction;
• wherein the stabilizing structure is configured such that upon application of negative pressure to the wound when the stabilizing structure is inserted into the wound, the stabilizing structure collapses more in the horizontal plane than in the z-direction, and the stabilizing structure collapses more in the x-direction than in the y-direction;
• and
• wherein the cells located farther away from the central transverse axis of the stabilizing structure are sized and configured to cause one or both longitudinal end portions of the stabilizing structure to collapse uniformly with a central portion of the stabilizing structure between the longitudinal end portions upon application of negative pressure.
