Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
64 words
An orthopedic article adapted to immobilize a body part, comprising (a) a flexible substrate having opposing surfaces impregnated with a curable liquid compound, and (b) a cover disposed on the surfaces that is permeable to water and impermeable to the curable liquid compound, said cover comprises a flexible sheet treated with a material selected from the group consisting of a fluorochemical and a silicone.
Claim 2
Dependent Claim
64 words
An orthopedic article adapted to immobilize a body part, comprising (a) a flexible substrate having opposing surfaces impregnated with a curable liquid compound, and (b) a cover disposed on the surfaces that is permeable to water and impermeable to the curable liquid compound, said cover comprises a flexible sheet treated with a material selected from the group consisting of a fluorochemical and a silicone.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
22 words
The article of claim 1, wherein the cover comprises a knitted, woven, or a non-woven fabric or foam treated with the material.
Claim 6
Dependent Claim
13 words
The article of claim 4, wherein the fabric is treated with a fluorochemical.
Claim 7
Dependent Claim
13 words
The article of claim 4, wherein the fabric is treated with a silicon.
Claim 8
Dependent Claim
15 words
The article of claim 4, wherein the curable compound is a water-curable isocyanate-terminated prepolymer resin.
Claim 9
Dependent Claim
21 words
The article of claim 4, wherein the amount of the material is from 0.01 to 10% by weight of the fabric.
Claim 10
Dependent Claim
21 words
The article of claim 4, wherein the amount of the material is from 0.25 to 5% by weight of the fabric.
Claim 11
Dependent Claim
37 words
The article of claim 1, further comprising a foam layer disposed on a side of the cover opposing one surface of the substrate, wherein said foam layer is adapted to contact the body part to be immobilized.
Claim 12
Dependent Claim
15 words
The article of claim 1, wherein the cover comprises a sealed envelope encasing the substrate.
Claim 13
Dependent Claim
33 words
The article of claim 1, wherein the apparent surface energy of the cover ranges from 15 to 40 dynes per centimeter and the cover has a porosity of less than about 10.5 seconds.
Claim 14
Dependent Claim
57 words
The article of claim 1, wherein the flexible sheet is a laminate comprising a treater layer adjacent to the flexible substrate and treated with the material, and at least one other layer, wherein the treated and other layers are selected from the group consisting of a woven web, a non-woven web, a knitted web and a foam.
Claim 15
Dependent Claim
17 words
The article of claim 1, wherein the cover has a porosity of about 1.0 second or less.
Claim 16
Dependent Claim
40 words
The article of claim 1, wherein the cover comprises a knitted, woven, or a non-woven fabric treated with the material disposed on one of the opposing surfaces and a foam treated with the material disposed on the other opposing surface.
Claim 17
Dependent Claim
48 words
The article of claim 1, wherein the cover comprises a knitted, woven, or a non-woven fabric treated with the material disposed on one of the opposing surfaces and adhesively attached to a foam treated with the material such that the cover forms an envelope encasing the flexible substrate.
Claim 18
Dependent Claim
40 words
The article of claim 1, in the form of a kit further comprising a separate cushion adapted to contact a body part to be immobilized and wherein the cover comprises a knitted, woven, or a non-woven fabric treated with material.
Claim 19
Independent Claim
72 words
A method of making an orthopedic article adapted to immobilize a body part comprising the steps of (a) impregnating a flexible substrate having opposing surfaces with a curable liquid compound, and (b) applying to the surfaces a cover comprising a flexible sheet that has been treated with a material selected from the group consisting of a fluorochemical and a silicone, that is permeable to water and impermeable to the curable liquid compound.
Claim 20
Independent Claim
72 words
A method of making an orthopedic article adapted to immobilize a body part comprising the steps of (a) impregnating a flexible substrate having opposing surfaces with a curable liquid compound, and (b) applying to the surfaces a cover comprising a flexible sheet that has been treated with a material selected from the group consisting of a fluorochemical and a silicone, that is permeable to water and impermeable to the curable liquid compound.
Claim 21
Dependent Claim
42 words
A method of immobilizing body part comprising the steps of (a) activating the curable liquid compound in the article of claim 1, (b) applying the article of claim 1 to the body part, and (c) allowing the curable liquid compound to cure.
Claim 22
Dependent Claim
17 words
The method of claim 19, wherein the curable compound is activated by soaking the article in water.
