A treatment system includes an dressing having a decompression layer and an occlusive layer that secures the dressing about a treatment site, and defines a treatment chamber within which the decompression layer is positioned. Operation of an air displacement device fluidly coupled to the chamber causes the decompression layer to compress away from the tissue site, resulting in a pulling force being imparted onto the treatment site. This decompression of the tissue site increases the perfusion of blood and other fluids, and advantageously may reduce swelling at the treatment site. To increase the degree of lifting of the treatment site, the decompression layer is advantageously constructed to exhibit a parallel plate effect during use of the treatment system. For example, the decompression layer is constructed having a center of stiffness located closer to an outwardly-facing surface of the decompression layer than a tissue-facing surface of the decompression layer.

Decompression therapy treatment system

A dressing may include a manifold and a spacer fabric. The manifold may have a first side configured to face the tissue site, a second side opposite the first side, a thickness between the first side and the second side, a first portion, and a second portion. The spacer fabric may extend between the first portion and the second portion and may comprise a first layer coupled to the first portion, a second layer coupled to the second portion, and a spacer layer extending between the first layer and the second layer. The first layer and the second layer may be perpendicular to the first side of the manifold. The dressing may be configured to contract more in a first direction than in a second direction, wherein the first direction is perpendicular to an extension direction of the spacer fabric. Other dressings, apparatus, systems, and methods are disclosed.

Dressing with spacer fabric to promote medial tension

An apparatus for promoting circulation through a subcutaneous lymph vascular network may comprise a first manifold layer, a second manifold layer coupled to the first manifold layer, and a cover layer coupled to the second manifold layer. The first manifold may have a first stiffness, and the second manifold may have a second stiffness greater than the first stiffness. In some embodiments, the apparatus may additionally have a fluid interface configured to fluidly couple at least one of the first manifold layer and the second manifold layer to a fluid conductor through the cover layer. The fluid conductor may be coupled to or configured to be coupled to a source of negative pressure.

Soft-tissue treatment with negative pressure

Disclosed embodiments may relate to dressings configured to provide negative-pressure wound therapy to a tissue site, while simultaneously shielding a portion of the tissue site from the negative pressure. For example, dressing assembly embodiments may comprise an outer dressing configured for applying negative-pressure wound therapy to a tissue site, and an underlying isolation patch configured for use under the outer dressing. The isolation patch may be configured to seal the portion of the tissue site so that it does not experience the negative pressure. Additionally disclosed are other apparatus, dressings, systems, and methods.

Negative-pressure wound therapy dressing with zone of ambient pressure

An apparatus for applying negative pressure to a tissue site of a patient may include a tissue interface, a cover, an aperture in the cover, and a sealing member. The tissue interface may have an anatomical shape configured to cover the tissue site. The cover may be configured to cover the tissue interface. The aperture in the cover may be fluidly coupled to the tissue interface. The sealing member may be configured to seal the cover to the patient, wherein the cover and the sealing member are configured to cooperate to form a sealed chamber containing the tissue interface. The tissue interface may be coupled to a source of negative pressure, which can be delivered to the tissue interface for distribution to the tissue site. The source of negative pressure may be coupled to the cover of the apparatus.
