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 method and apparatus for disrupting material at a tissue site is described. A contact layer may be selected for use on the tissue site and positioned adjacent to the tissue site. The contact layer may include walls defining a plurality of through-holes. A sealing member may be positioned over the contact layer and sealed to tissue surrounding the tissue site to form a sealed space enclosing the contact layer. A negative-pressure source may be fluidly coupled to the sealed space. The negative-pressure source may supply negative pressure to the sealed space and the contact layer to draw tissue into the through-holes to form nodules. The negative pressure may be vented from the sealed space to release the nodules.

Abstract: A wound therapy system includes an instillation fluid canister configured to contain an instillation fluid, a pump fluidly coupled to the instillation fluid canister and operable to deliver the instillation fluid from the instillation fluid canister to a wound, a user interface configured to receive user input indicating one or more geometric attributes of the wound, and a controller electronically coupled to the pump and the user interface. The controller is configured to determine a volume of the wound based on the user input, determine a volume of the instillation fluid to deliver to the wound based on the volume of the wound, and operate the pump to deliver the determined volume of the instillation fluid to the wound.

Abstract: A dressing includes a foam layer, a plurality of cores extending substantially through the foam layer, and a drape sealable over the foam layer and a wound bed. The drape is couplable to a pump operable to create a negative pressure in the substantially-airtight volume. Each core is substantially removable from the foam layer to reveal a channel through the foam layer. Each core is defined by perforations that facilitate separation of the core from the foam layer.

Abstract: A wound therapy system includes a dressing an instillation pump fluidly communicable with the dressing and configured to provide instillation fluid to the dressing, a negative pressure pump fluidly communicable with the dressing and configured to remove air from the dressing, and a control circuit communicably coupled to the instillation pump and the negative pressure pump. The control circuit is configured to control the instillation pump to provide an amount of the instillation fluid to the dressing, provide a soak period, and control the negative pressure pump to provide a cyclic variation of negative pressure at the dressing.

Abstract: A wound therapy system includes a therapy unit, a wound dressing and an optional controller. The therapy unit is configured to deliver instillation fluid to a wound site. The wound dressing is formed from a plurality of discrete, individual blocks that are selectively separable from one another along a plurality of separation-lines, allowing the wound dressing to be customized to the shape and size of the wound site. By calculating the remaining blocks that define the wound dressing following customization, the volume of the wound dressing may be determined. The controller may be configured to deliver fluid to the wound site based on this calculated volume. The controller may also optionally be used to gauge the healing of the wound site over time by monitoring the changes in volume of customized wound dressings as wound dressings are replaced during the course of treatment of the wound site.
