Abstract: The disclosure concerns various devices implemented to provide a therapeutic gas rich environment to promote healing, reduce fibrosis and scar formations while maintaining anti-inflammatory, anti-thrombotic, antimicrobial, and vasodilating properties. The device generally includes a gas-donor composition that is embedded within a fibrous holding layer. Coupled to one side of the fibrous holding layer is a water-permeable layer and coupled to an opposite side of the fibrous holding layer is a gas-permeable layer. The water-permeable layer is configured to receive and communicate water to the gas-donor composition, wherein upon contact with the water, the gas-donor composition is configured to deliver a therapeutic gas through the gas-permeable layer to a treatment site of a subject.

Abstract: The disclosure concerns various medical devices implemented to provide a nitric oxide rich environment for anti-microbial or anti-thrombogenic benefits. The medical device generally includes a nitric oxide donor material that is contained within a sealed cavity, and a transport medium that defines and captivates the entirety of the cavity, wherein the transport medium is permeable to both water and nitric oxide. As the nitric oxide donor material becomes saturated with water from the surrounding tissue or fluids, nitric oxide is chemically released, and the resulting nitric oxide is communicated through the transport medium to a treatment site for anti-microbial and anti-thrombogenic benefits.
