Abstract
This disclosure includes wound dressings and systems with remote oxygen generation for topical wound therapy and related methods. Some systems include a dressing for facilitating delivery of oxygen to the target tissue, the dressing having: a first manifold that defines a plurality of gas passageways and is configured to allow communication of oxygen to the target tissue; a gas-occlusive layer configured to be disposed over the first manifold and coupled to tissue surrounding the target tissue such that: an interior volume is defined between the gas-occlusive layer and the target tissue; and the gas-occlusive layer limits escape of oxygen from the interior volume between the gas-occlusive layer and the tissue surrounding the target tissue; a container outside the interior volume, the container having a sidewall that defines a chamber configured to be in fluid communication with the interior volume; and an oxygen-generating material disposed within the chamber of container and configured to release oxygen when exposed to water.
