Abstract
The present invention relates to wound closure devices, systems and methods. Embodiments of the invention facilitate closure of the wound by preferentially contracting under negative pressure to provide for movement of the surrounding tissues. Some embodiments may utilize tissue securing portions that aid in securing the invention within a wound.
Claims36
An apparatus for treating a wound with negative pressure wound therapy, comprising:
- a stabilizing structure having an oculiform shape for insertion into a wound, the stabilizing structure configured to collapse more in a horizontal plane parallel to a length and a width of the stabilizing structure than in a vertical plane perpendicular to the horizontal plane.

A wound closure device, comprising:
- a stabilizing structure for insertion into a wound;
- a top layer of foam attached to a top of the stabilizing structure, the top layer of foam conforming to the shape of the stabilizing structure;
- a middle layer of foam attached to a bottom of the stabilizing structure, the middle layer of foam conforming to the shape of the stabilizing structure;
- and
- a bottom layer of foam, the bottom layer of foam attached to the middle layer of foam, the bottom layer of foam comprising a lip that extends outward into the surrounding tissue of the wound.
A method of treating a wound, comprising:
- providing a stabilizing structure;
- attaching a top layer of foam to the stabilizing structure;
- attaching a bottom layer of foam to the stabilizing structure, the bottom layer of foam comprising a lip extending outward into the surrounding tissue;
- and
- inserting the stabilizing structure into the wound, wherein after insertion the lip engages tissue to prevent the stabilizing structure from lifting upwards in a direction out of the wound.
