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.
