Abstract: Disclosed embodiments relate to devices and systems for providing negative-pressure therapy, instillation, and/or pressure-sensing at a tissue site, and to methods of manufacturing such devices and systems. In some embodiments, a fluid bridge may comprise a first layer of foam with a plurality of supports extending from at least an inner surface, and a second layer. The first and second layers may be coupled together around the perimeter to form one or more enclosed fluid pathways, for example extending from a port to an aperture. In some embodiments, at least the first layer may be formed of closed-cell foam.

Abstract: A cutting template for use with a negative pressure wound therapy system includes a substantially rigid body. The body includes a top surface, a bottom surface, a height, and a recess. The top surface is configured to engage a drape layer. The bottom surface is configured to engage a dressing layer. The height is defined between the top surface and the bottom surface. The height is configured to create a gap between the drape layer and the dressing layer. The recess is disposed substantially about a perimeter of the body. The recess is configured to receive an edge of a cutting tool so that an opening is formed in the drape layer when the edge is traversed about the perimeter.

Abstract: A multi-layer dressing for treating tissue with negative pressure, instillation, or both. In some embodiments a first layer may be formed from reticulated foam having a series of holes. A second layer disposed adjacent to the first layer may be formed from a perforated polymer. The dressing may optionally include a third layer formed from a soft polymer, such as a silicone gel. The third layer may also have perforations or apertures. The third layer is generally oriented to face a tissue site, and may be disposed adjacent to the first layer so that the first layer is disposed between the third layer and the first layer. The perforations or apertures in the third layer may be registered with one or more perforations in the first layer.

Abstract: A wound therapy system includes a negative pressure circuit, a pump, a pressure sensor, and a controller. The negative pressure circuit applies negative pressure to a wound. The pump is fluidly coupled to the negative pressure circuit and produces a negative pressure at the wound or within the negative pressure circuit. The pressure sensor measures the negative pressure within the negative pressure circuit or the wound. The controller performs a testing procedure including a first drawdown period, a leak rate determination period, a vent period, and a second drawdown period. The controller is configured to receive one or more pressure measurements of the pressure sensor over the leak rate determination period to determine a leak rate parameter, monitor an amount of elapsed time over the second drawdown period to determine a drawdown parameter, and estimate a volume of the wound based on the leak rate parameter and the drawdown parameter.

Abstract: A system, apparatus and method for delivering negative pressure and vibrations proximate a wound site. The system comprises a dressing adapted to be fluidly coupled to the wound site and further adapted to translate vibrations to the wound site. A pad is coupled to a negative pressure source and to the dressing. The pad is also coupled to a vibration module. The system further comprises a drape covering the dressing and the pad and forming a seal between the wound site and the environment. The vibration module fluidly couples to the dressing and provides vibrations during application of negative pressure.

Abstract: A wound dressing includes a contact layer and a support layer. The contact layer is configured to engage and provide surface deformation, slough removal, or debride a wound bed and has a first side and a second side, the second side facing the wound surface. The support layer also has a first side and a second side, the second side facing the first side of the contact layer, wherein a portion of the support layer is configured to overlay a periwound surrounding the wound bed.

Abstract: A volume of a wound is estimated using a dynamic pressure response measured during instillation of fluid to the wound using a negative pressure wound therapy system. A previously estimated wound volume may be used to detect and prevent overfill of fluid to the wound during future instillation events. For example, real-time pressure measurements may be compared to model data representative of expected pressure at a wound having a volume equal to the previously estimated wound volume, with instillation being stopped if the observed pressure varies from the expected pressure. A comparison of a total volume of fluid instilled to the wound may also be compared to the previously estimated wound volume to prevent overfill. The comparison of wound volume estimated based on an instillation event may also be compared to a wound volume estimated using other methods to provide a higher confidence wound volume estimate.
