Disclosed herein are devices, systems and methods for using such devices and systems for treating incisions and wounds. In an aspect, disclosed is a device having a generally planar tension relief module and a flexible sealant structure sized to cover the tension relief module, the flexible sealant structure comprising a lower adhesive surface. The tension relief module includes a conduit structure having a plurality of support structures on an upper surface of the conduit structure and at least one opening extending through the conduit structure from a lower surface to the upper surface. At least a portion of the conduit structure is adapted to be aligned with a longitudinal axis of the incision. The tension relief module also includes opposing adhesive structures coupled to the conduit structure. The lower adhesive surface of the flexible sealant structure and the upper surface of the conduit structure form a flow pathway.

The present disclosure provides in part improved apparatuses, systems, and methods for providing therapy to a wound. A system can include a first power source configured to power an electronic component and a second power source configured to power the electronic component in place of the first power source. Responsive to a first condition, the second power source can power the electronic component in place of the first power source. In some cases, the system can include a pressure source that is configured to provide negative pressure to a wound dressing positioned over a wound. The wound dressing can support the first power source or the second power source.

Dressings and kits for use in negative-pressure therapy are provided herein comprising one or more manifolds and a polymer film laminated to the one or more manifolds. At least one manifold is felted and the manifolds may be placed in a stacked configuration and differentially collapse under negative pressure. Methods of making and using the dressings are also provided herein.

Disclosed herein are embodiments of a wound treatment apparatus employing hydrophobic and hydrophilic dressing materials and/or coating of the layers of a wound dressing. In some embodiments, the hydrophobic and hydrophilic dressing materials and/or coating controls the migration of fluid within the wound dressing.

Systems, methods, and apparatuses for regulating the delivery of negative-pressure therapy are described. The system includes a negative-pressure source, an energy source, and a switch. The switch can include a first conductor electrically coupled to the negative-pressure source, a second conductor electrically coupled to the energy source, and a diaphragm having a first position electrically coupling the first conductor to the second conductor and a second position separated from the first conductor and the second conductor. The diaphragm is configured to move between the first position and the second position in response to a differential between a control pressure and a therapy pressure.

A dressing for treating tissue with negative pressure is provided herein comprising a composite of dressing layers, including a release film, a perforated coated polymer film, a manifold, and an adhesive cover. Additionally, a method of manufacturing the dressing may comprise applying a cross-linkable polymer to a polymer film, curing the cross-linkable polymer to a gel layer to form a coated polymer film, and perforating the coated polymer film to form fluid restrictions, such as slits and/or slots, though the coated polymer film.

A system, method, and apparatus are disclosed for dressing a wound and for minimizing scarring. The apparatus promotes scar-minimizing healing of a wound where negative pressure wound therapy is applied, and comprises a wound contact layer containing silicone, polysiloxanes, or other related compounds.

A barrier for use in negative pressure wound therapy can include a base layer and surface structures. The barrier can be used to reduce or prevent tissue ingrowth. A method of using a negative pressure wound therapy system can include positioning a perforated barrier in a wound. After positioning the perforated barrier in the wound, positioning a pad in the wound on top of the perforated barrier, positioning a seal on top of the wound to at least partially seal the perforated barrier and the foam in the wound, and applying negative pressure wound therapy to the wound.

A system for treating open wounds includes a foam material configured for pouring, spraying, injecting or spreading on a wound bed. The foam material can comprise a base component and a curing component, which can be pre-mixed before application, or mixed in situ as the components are being applied to the wound site. A third component can comprise a sacrificial porogen. Foam can be placed in the wound bed as a wound liner on the wound surfaces. An additional foam insulation can provide a foam filler partially contained by the wound liner and generally flush with a patient's epidermis. A method of treating open wounds includes the steps of applying the wound liner and filler components. An optional step comprises covering the wound liner with a semi-permeable (breathable) membrane and mounting inlet and outlet ports thereon for introducing healing compositions as input, and extracting wound exudates as output.

This invention relates to the design of tissue covering elements for use in vacuum assisted tissue apposition systems, wherein the geometry of the covering elements favours the application of contractile forces over compressive or extensive forces at the tissue interface.
