Abstract
Abstract An orthopedic brace is provided having one or more pads mounted thereon to provide secure and comfortable support for the brace when positioned against the body of a user. Each pad includes at least one pneumatic bladder, formed from a flexible skin permanently sealed to enclose a volume of gas therein. In a first embodiment, the brace has a point pad mounted thereon which is configured to conform to a surface of the body overlying a skeletal protrusion. The point pad contains a bladder having a substantially closed-loop configuration circumscribing the skeletal protrusion and having an interior opening to receive the protrusion. In a second embodiment, the brace has an areal pad mounted thereon which is configured to conform to a surface of the body overlying a curved, but relatively level, skeletal structure or soft tissue. The areal pad is a plurality of interconnected gas-inflated chambers that are maintained in fluid isolation from one another by flexible seams positioned between adjacent chambers. Alternatively, the areal pad is a bladder having a plurality of interconnected gas-inflated segments that are in fluid communication with one another via flow channels provided through the flexible seams positioned between adjacent segments. In either case, the flexible seams act as a pivot enabling articulation of the pad.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
192 words
An orthopedic brace positionable on the body of a user comprising: a rigid hinge surface joining two rigid arms, said hinge surface positionable opposite a knee condyle of the user and adaptable to apply pressure thereto; a first sheet of an elastically deformable film positionable between said surface and the body of the user; a second sheet of an elastically deformable film positionable between said first sheet and the body of the user; a first seam sealingly joining said second sheet to said first sheet, thereby defining at least a portion of an outer perimeter of a first substantially fluidtight bladder between said first and second sheets, wherein said first bladder is formed substantially in the shape of a toroid; a second seam sealingly joining said second sheet to said first sheet, thereby defining at least a portion of an outer perimeter of a second bladder between said first and second sheets, said second bladder in fluid isolation from said first bladder; a volume of fluid contained within said first bladder, said volume of fluid sufficient to provide said first bladder with a height greater than the height of said second bladder.
Claim 2
Dependent Claim
192 words
An orthopedic brace positionable on the body of a user comprising: a rigid hinge surface joining two rigid arms, said hinge surface positionable opposite a knee condyle of the user and adaptable to apply pressure thereto; a first sheet of an elastically deformable film positionable between said surface and the body of the user; a second sheet of an elastically deformable film positionable between said first sheet and the body of the user; a first seam sealingly joining said second sheet to said first sheet, thereby defining at least a portion of an outer perimeter of a first substantially fluidtight bladder between said first and second sheets, wherein said first bladder is formed substantially in the shape of a toroid; a second seam sealingly joining said second sheet to said first sheet, thereby defining at least a portion of an outer perimeter of a second bladder between said first and second sheets, said second bladder in fluid isolation from said first bladder; a volume of fluid contained within said first bladder, said volume of fluid sufficient to provide said first bladder with a height greater than the height of said second bladder.
Claim 3
Dependent Claim
20 words
An orthopedic brace as recited in claim 1 further comprising means for connecting said first sheet to said rigid surface.
Claim 4
Dependent Claim
35 words

Claim 5
Dependent Claim
20 words
An orthopedic brace as recited in claim 3 wherein said elastic cushion is relatively less elastic than said first sheet.
Claim 6
Dependent Claim
20 words
An orthopedic brace as recited in claim 3 further comprising means for connecting said first sheet to said rigid surface.
Claim 7
Dependent Claim
53 words
An orthopedic brace as recited in claim 5 wherein said connecting means is a hook and loop fastener comprising a hook component and a loop component, and further wherein one component of said hook and loop fastener is attached to said elastic cushion and the other component is attached to aid rigid surface.
Claim 8
Dependent Claim
21 words
An orthopedic brace as recited in claim 1 wherein said first bladder is adaptable in size to circumscribe the knee condyle.
Claim 9
Dependent Claim
18 words
An orthopedic brace as recited in claim 7 wherein said second bladder is positionable opposite the knee condyle.
Claim 10
Dependent Claim
184 words
A pad mountable on an orthopedic brace to support the brace against a user's body when positioned thereon, said pad comprising: a first sheet of an elastically deformable film having two sides; a second sheet of an elastically deformable film positioned on the first side of said first sheet; means for connecting said first sheet to the brace; a first seam sealingly joining said second sheet to said first sheet, thereby defining at least a portion of an outer perimeter of a first substantially fluidtight bladder between said first and second sheets; a second seam sealingly joining second sheet to said first sheet, thereby defining at least a portion of an outer perimeter of a second bladder between said first and second sheets, said second bladder in fluid isolation from said first bladder, wherein said first bladder is formed in the shape of a toroid and said second bladder is concentric with said toroid; a volume of fluid contained within said first bladder, said volume of fluid sufficient to provide said first bladder with a height greater than the height of said second bladder.
Claim 11
Dependent Claim
