Patent ID: 8702711

Claim:
A bladder for applying a treatment to a defect in a first bone or a second bone of two bones forming a joint, the bladder comprising: a reduced-pressure bladder having an exterior wall forming a reduced-pressure chamber with an interior surface, an opening to the reduced-pressure chamber adapted to substantially surround the defect when positioned against the first bone, and a reduced-pressure port in fluid communication with the reduced pressure chamber for receiving reduced pressure from a source of reduced pressure; a manifold disposed within the reduced-pressure chamber and having a surface adapted to form a cavity with a portion of the interior surface when reduced pressure is provided to the reduced-pressure chamber and also providing structural support between the interior surface and the exterior wall to prevent the cavity from collapsing, wherein the reduced-pressure bladder seals the opening around the defect that closes the cavity and is thereby exposed to the reduced pressure within the cavity; and a bracing bladder having an exterior wall forming a bracing chamber for receiving a fluid, a first surface of the exterior wall affixed to the reduced-pressure bladder opposite the opening, a second surface of the exterior wall opposing the first surface adapted to be positioned against the second bone, and a port for providing the fluid to the bracing chamber under a positive pressure, the bracing bladder being inflatable with the fluid to provide a cushion between the reduced-pressure bladder and the second bone when the positive pressure is provided to the bracing chamber.
