US 12,178,777 B2 · Soft-tissue treatment with negative pressure

Abstract

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.

Dependent claims

An apparatus for promoting circulation through a subcutaneous lymph vascular network, the apparatus comprising:

a manifold layer having a first stiffness, the first stiffness is from about 800 gram-force to about 1000 gram-force;
a support layer adjacent to the manifold layer, the support layer comprising one or more apertures, and the support layer having a second stiffness greater than the first stiffness;
a cover adjacent to the support layer;
and
a fluid interface configured to fluidly couple at least one of the manifold layer and the support layer to a fluid conductor;
wherein when negative pressure is applied to one or more of the manifold layer and the support layer at least a portion of the apertures are visible through the cover.
