A flexible dressing for applying to a tissue site for determining the extent of debridement required to remove non-viable tissue is disclosed. Some embodiments of the dressing may be in the form of a multi-layer drape having an integrated tissue viability indicator system. Some embodiments may also include a system of shapes or a grid pattern printed or embossed on a surface of the drape for providing guidance during an ensuing debridement or amputation procedure.

Devices and methods for encapsulating a portion of a wound dressing with biocompatible coating are disclosed. In some embodiments, a method includes coating a first side of a flexible wound contact layer of the wound dressing with a hydrophobic coating. The first side of the wound contact layer can support a plurality of electronic components. The method can further include coating a second side of the wound contact layer opposite the first side with the hydrophobic coating. The wound contact layer can be formed at least partially from hydrophilic material.

Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.

Systems and methods for providing negative-pressure therapy with fluid instillation therapy and, more specifically, scheduling and controlling both the negative pressure therapy and the fluid instillation therapy are described. The method may comprise applying negative pressure to the dressing based on an initial therapy configuration, and monitoring negative pressure parameters associated with the application of negative pressure to the dressing to identify negative pressure alarm conditions. The method may further comprise applying instillation fluid to the dressing based on the initial therapy configuration, and monitoring instillation parameters associated with the application of instillation fluid to the dressing to identify instillation alarm conditions. Both may include modifying the initial therapy configuration to generate a modified therapy configuration in response to the negative pressure and instillation alarm conditions identified.
