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.

Claims (43)

1 .- 58 . (canceled)

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

a manifold layer having a first stiffness from about 800 gram-force to about 1000 gram-force, the manifold layer configured to be positioned proximate a tissue site; and

a support layer coupled to the manifold layer, the support layer having a second stiffness from about 800 gram-force to about 3000 gram-force.

60 . The apparatus of claim 59 , further comprising a fluid interface configured to fluidly couple at least one of the manifold layer and the support layer to a fluid conductor.

61 . (canceled)

62 . The apparatus of claim 59 , wherein the support layer comprises one or more apertures.

63 . The apparatus of claim 62 , further comprising a cover adjacent to the support layer.

64 . (canceled)

65 . The apparatus of claim 63 , wherein when negative pressure is applied to one or more of the manifold layer and the support layer at least a portion of the cover is configured to be drawn into the one or more apertures to form one or more indentations, and wherein the indentations are visible.

66 . (canceled)

67 . The apparatus of claim 59 , wherein:

the manifold layer has a first thickness; and

the support layer has a second thickness less than the first thickness.

68 . (canceled)

69 . (canceled)

70 . The apparatus of claim 59 , wherein the manifold layer comprises open-cell foam.

71 . (canceled)

72 . (canceled)

73 . The apparatus of claim 59 , wherein the support layer comprises a closed-cell foam.

74 . The apparatus of claim 59 , wherein the support layer comprises neoprene foam.

75 . (canceled)

76 . (canceled)

77 . (canceled)

78 . (canceled)

79 . (canceled)

80 . The apparatus of claim 59 , wherein the support layer comprises rubber.

81 . A method of treating a tissue site to promote circulation through a subcutaneous lymph vascular network, the method comprising:

applying a manifold layer, a support layer, and a cover over the tissue site;

fluidly coupling a source of negative pressure to at least one of the manifold layer and the support layer through the cover layer; and

applying negative pressure from the source of negative pressure to the manifold layer;

wherein the manifold layer has a first thickness and a first stiffness, and the support layer has a second thickness and a second stiffness, the second thickness less than the first thickness.

82 . (canceled)

83 . The method of claim 81 , wherein the manifold layer is between the tissue site and the support layer.

84 . The method of claim 81 , wherein the second stiffness greater than the first stiffness.

85 . The method of claim 81 , wherein first stiffness is from about 800 gram-force to about 1000 gram-force and the second stiffness is from about 800 gram-force to about 3000 gram-force.

86 . The method of claim 81 , wherein the first stiffness is about 910 gram-force.

87 . The method of claim 81 , wherein the second stiffness is from about 1000 gram-force to about 2000 gram-force.

88 . The method of claim 81 , wherein the second stiffness is from about 1200 gram-force to about 1500 gram-force.

89 . The method of claim 81 , wherein the support layer comprises a closed-cell foam.

90 . The method of claim 81 , wherein the support layer comprises neoprene foam.

91 . The method of claim 81 , wherein the manifold layer comprises open-cell foam.

92 .- 112 . (canceled)
