Abstract: In some examples, a system for treating a tissue site may include a dressing, at least one fluid sampling conduit, and at least one fluid sampling assembly. The dressing may be configured to be positioned at the tissue site. The at least one fluid sampling assembly may be configured to be in fluid communication with the tissue site through the at least one fluid sampling conduit. The at least one fluid sampling assembly may include a fluid vessel for receiving a fluid from the tissue site. The fluid may be a sampling fluid communicated directly from the tissue site and representative of the physiological condition of the tissue site. Other devices, systems, and methods are disclosed.

Abstract: A wound dressing includes an inelastic absorbent layer, an elastic film, and a plurality of welds. The inelastic absorbent layer is configured to absorb wound fluid and has a first side and a second, wound-facing side. The elastic film is configured to elastically stretch when a stretching force is applied to the wound dressing and elastically recover when the stretching force is removed. The plurality of welds fix the elastic film to the first side of the inelastic absorbent layer such that the elastic film and the inelastic absorbent layer elastically stretch and elastically recover as a unit.

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.

Abstract: A wound dressing includes a hydrophilic foam layer, a plurality of wicking strips, and a drape layer. The hydrophilic foam layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The plurality of wicking strips also have a first side and a second side, the second side configured to face the first side of the hydrophilic foam layer. The drape layer also has a first side and a second side, the second side configured to face the first side of the plurality of wicking strips. One or more of the plurality of wicking strips also have a removable tab, wherein the tab extends beyond a periphery of the wound dressing.

Abstract: In some aspects, the present invention provides an active dressing for transfer of superficial epidermal biopsies to a wound site, where the dressing can enhance keratinocyte out growth from the biopsies at the wound site and improve the rate of re-epithelization. In some embodiments, the dressing can include a perforated dehydrated amniotic membrane sheet that is coupled to a backing sheet having suitable adhesive properties. The perforations can have appropriate dimensions and distributions for capturing and transferring the skin biopsies. Without being limited to any particular theory, the amniotic membrane sheet can enhance the re-epithelization of the wound site to which the biopsies are transferred, e.g., by supplying signaling proteins and extra-cellular matrix (ECM) components.
