Abstract: Wound dressings, systems, and methods are presented for treating a wound on a patient's limb, such as a venous leg ulcer. The dressings, systems, and methods involve creating airflow within the dressing to vaporize and remove liquid. The airflow may begin when the dressing becomes saturated. The dressings may be used to provide compression and reduced pressure to the wound. Other systems, methods, and dressings are presented herein.

Abstract: A wound dressing includes an inelastic absorbent layer, an elastic film, and a plurality of welds. The inelastic absorbent layer is configured to absorb wound fluid and has a first side and a second, wound-facing side. The elastic film is configured to elastically stretch when a stretching force is applied to the wound dressing and elastically recover when the stretching force is removed. The plurality of welds fix the elastic film to the first side of the inelastic absorbent layer such that the elastic film and the inelastic absorbent layer elastically stretch and elastically recover as a unit.

Abstract: A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominal contents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.

Abstract: Systems and methods for treating a plurality of tissue sites include a multi-port therapy unit. The multi-port therapy unit includes a plurality of patient-side ports each fluidly coupled to a plurality of conduits and a fluid reservoir fluidly coupled to the plurality of ports. A plurality of pressure sensors are associated with the plurality of patient-side ports to determining a pressure associated with each conduit. A controller is operatively coupled to the plurality of pressure sensors to receive treatment pressure data, monitor pressure for each pressure sensor of the plurality of pressure sensors, and signal an alarm condition if the pressure is outside of a pre-selected range. The system includes a reduced-pressure source fluidly coupled to a dressing at each tissue site through the multi-port therapy unit.

Abstract: Skin graft harvesting systems and methods are disclosed that utilize sensors to automate the harvesting of skin grafts or assist a user in deciding when the skin graft is ready to be harvested. Such systems and methods can reduce the burden of visual observation and ensure greater reliability and consistency of the grafts. The invention is particularly useful with harvesters that rely upon suction and/or heating to raise a plurality of small or “micro” blisters simultaneously.

Abstract: A reduced-pressure system for delivering reduced pressure for medical purposes to a desired site and to receive fluids in one instance includes a reservoir having an interior space operable to contain the fluids. A reduced-pressure delivery conduit is placed in fluid communication with the interior space for delivering the reduced pressure to the desired site. A source conduit and a pressure sensor conduit are placed in fluid communication with the interior space. A pressure sensor is placed in fluid communication with the pressure sensor conduit. A reduced-pressure source is placed in fluid communication with the source conduit. A reduced-pressure control unit is associated with the pressure sensor and the reduced-pressure source and is operable to receive pressure data from the pressure sensor and supply data from the reduced-pressure source and to determine when a reservoir-full/blockage condition exists. Other systems and methods are presented.
