Abstract
A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Some embodiments may utilize a hydrophilic organ protection layer.
Claims20
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 bottom layer of foam positioned or positionable underneath the stabilizing structure, the bottom layer of foam comprising a lip that is configured to extend outward relative to the stabilizing structure;
- and
- wherein the bottom layer of foam comprises a hydrophilic foam.

A method of treating a wound, comprising:
- providing a stabilizing structure;
- attaching a top layer of foam to a top of the stabilizing structure;
- attaching a hydrophilic bottom layer of foam to a bottom of 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.
