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 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: An apparatus for treating a tissue site comprising a negative-pressure source configured to be fluidly coupled to the tissue site; an instillation source configured to be fluidly coupled to the tissue site; and a controller operatively coupled to the negative-pressure source and to the instillation source. The controller can be configured to operate the negative-pressure source and the instillation source to intermittently deliver negative pressure to the tissue site for a negative-pressure interval and deliver instillation fluid to the tissue site for an instillation interval. A purge volume of instillation fluid may be delivered to the tissue site at a purge frequency. In some examples, the purge volume may be delivered through the second fluid conductor and removed through the first fluid conductor during a negative-pressure interval.

Abstract: A customizable wound treatment system for treating multiple zones of a wound includes a dressing configured for use with a first zone and a second zone of a wound that includes a first foam layer placed over the first zone, a second foam layer placed over the second zone, a first drape layer disposed over the first foam layer and beneath the second foam layer, and a second drape layer disposed over the second foam layer. The customizable wound treatment system includes a negative pressure source pneumatically coupled to the first foam layer and the second foam layer and operable to create a negative pressure at the first zone and the second zone and a fluid instillation pump fluidly coupled to the first foam layer and configured to instill a treatment fluid to the first zone.

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.

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: In one example embodiment, a system for treating a tissue site is disclosed comprising a dressing adapted to contact the tissue site and provide a fluid seal between a therapeutic environment and a local external environment, and a solution source fluidly coupled to the dressing and adapted to deliver an antimicrobial solution comprising a peroxy α-keto carboxylic acid, such as peroxy pyruvic acid, to the tissue interface. The system may further comprise a negative-pressure source fluidly coupled to the dressing and adapted to provide negative pressure to the therapeutic environment after delivery of the antimicrobial fluid to the therapeutic environment. In another example embodiment, a method for treating a tissue site is disclosed comprising positioning a tissue interface to contact the tissue site, covering the tissue interface and the tissue site with a drape to provide a fluid seal between the therapeutic environment and the local external environment, and delivering an antimicrobial solution comprising peroxy α-keto carboxylic acid to the therapeutic environment before providing negative pressure to the therapeutic environment.
