Abstract: A reduced-pressure treatment system for treating a wound on a patient includes a composite manifold that may help prevent or minimize injury to a wound edge of the wound being treated with reduced pressure. The composite manifold includes a perimeter manifold member and an inboard manifold member. The perimeter manifold member is designed to not collapse substantially under reduced pressure in a therapy range. The perimeter manifold member may be more rigid with respect to compressibility than the inboard manifold member. A sealing member is used to form a fluid seal over the wound, and a reduced-pressure subsystem provides reduced pressure to the composite manifold. Other systems, methods, and dressings are presented.

Abstract: A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A controller for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A power management motor control for varying pump drive frequency and managing a portable power supply is provided to increase battery life and improve patient mobility.

Abstract: A negative pressure wound dressing for use with breast incisions. The wound dressing includes a drape layer, a manifold layer, a base layer, and a reduced pressure interface. The drape layer has a first surface and a second, wound-facing, surface. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The manifold layer has a first surface and a second, wound-facing surface. The manifold layer has a perimeter defined by a first convex curved side surface defining a first lobe, a second convex curved side surface defining a second lobe, and a connecting portion between the first lobe and the second lobe. The base layer is configured to: (i) couple the drape layer to the manifold layer, and (ii) the dressing to a patient's tissue. The reduced pressure interface is integrated with the drape layer.

Abstract: A treatment system includes an dressing having a decompression layer and an occlusive layer that secures the dressing about a treatment site, and defines a treatment chamber within which the decompression layer is positioned. Operation of an air displacement device fluidly coupled to the chamber causes the decompression layer to compress away from the tissue site, resulting in a pulling force being imparted onto the treatment site. This decompression of the tissue site increases the perfusion of blood and other fluids, and advantageously may reduce swelling at the treatment site. To increase the degree of lifting of the treatment site, the decompression layer is advantageously constructed to exhibit a parallel plate effect during use of the treatment system. For example, the decompression layer is constructed having a center of stiffness located closer to an outwardly-facing surface of the decompression layer than a tissue-facing surface of the decompression layer.
