Abstract: A system that includes a biocompatible polymeric matrix and a separately-stored fluid for improving delivery of a therapeutic gas to an area beneath a surface of intact skin or a wound site is provided. The system can preserve the therapeutic gas in the matrix such that its concentration remains generally constant until the system is ready for use, at which time the separately-stored fluid can be added or exposed to the matrix to activate the matrix and thus increase the permeability of the biocompatible polymeric matrix to the therapeutic gas, thus facilitating delivery of the therapeutic gas for the purpose of the treatment of wounds and intact skin is provided. A method of using the, as well as a deactivated matrix and its method of use for delivery of a therapeutic gas, are also provided.

Abstract: A dressing or device to distribute pressure for the purpose of prevention and treatment of wounds and intact skin is provided. The pressure distributing properties are achieved by a closed cell foam material that is in direct contact with the intact skin or wound and that can also have the ability to manage and absorb moisture. These unique characteristics creates a flexible, and easy to use dressing that can be cut to size and applied to any desired location on a patient.
