Abstract
A system for applying negative pressure to a joint positioned in a treatment area. The system includes a negative pressure dressing. The negative pressure dressing includes a compressive layer and a sealing layer. The compressive layer includes a first surface and a second, treatment area-facing. The compressive layer further includes a first elongated portion configured to be positioned proximate the joint. The first elongated portion includes a first end and a second end. The compressive layer further includes a second elongated portion spaced from the first elongated portion and configured to be positioned proximate the joint. The second elongated portion includes a first end and a second end. The compressive layer further includes an interconnecting portion extending between the first elongated portion and the second elongated portion. The interconnecting portion is configured to overlie at least a portion of the joint. The compressive layer further includes a plurality of channels formed in the first surface and extending proximate the second surface. The plurality of channels is formed in at least one of the first end and the second end of the first elongated portion and at least one of the first end and the second end of the second elongated portion. The sealing layer is configured to form a seal around a perimeter of the negative pressure dressing.
