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.

Wound dressing with semi-rigid support to increase disruption using perforated dressing and negative pressure wound therapy

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.

Disruptive dressing for use with negative pressure and fluid instillation

In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

Dressing providing apertures with multiple orifice sizes for negative-pressure therapy

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.

Wound therapy system with instillation therapy and dynamic pressure control

Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.

Low profile instillation and negative-pressure bridge

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.

Wound therapy system with wound volume estimation using geometric approximation

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.

Wound dressing with multiple treatment zones

In some non-limiting examples, a system for stimulating tissue growth at a tissue site may include a porous foam and a moisture barrier. The porous foam may include an exterior-facing surface, a tissue contact surface, and a plurality of struts positioned at the tissue contact surface. The plurality of struts may be configured to contact the tissue site and to create tissue deformation at the tissue site without the application of a reduced pressure. The moisture barrier may be configured to cover the exterior-facing surface of the porous foam and to trap moisture at the tissue site. Also provided are other systems, apparatus, and methods suitable for stimulating tissue growth.

Granulating dressing for low exuding chronic wounds

A dressing interface for connecting a negative-pressure source to a dressing may have a coupling member comprising an aperture, a first adhesive region having a first region peel strength, and a second adhesive region having a second region peel strength less than the first region peel strength. The dressing interface may further have a flange coupled to the coupling member, and a conduit housing coupled to the flange and extending through the aperture in the contact layer.

Removable and replaceable dressing interface for a negative-pressure therapy system

A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more drive elements arranged about a film layer, by which the drive elements are attached to the wound interface layer. Activation of the drive elements is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. The drive elements may include one or more drive members formed of a material having a shape memory effect configured to transition the drive members between expanded and collapsed configurations and/or one or more motors configured to translate or oscillate the active layer. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.

Method and system for providing active tissue site debridement

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.

Cutting template for a negative pressure wound therapy drape

A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more transmission layers that are arranged about a central post. Activation of the transmission layers is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. A drive unit is operably attached to the central post. The drive unit is configured to generate and transfer a vibrational energy and/or a rotational movement to the transmission layer(s) via the central post. The resultant vibration and/or rotation of the transmission layer(s) is imparted onto the wound interface layer, thereby effectuating the desired movement of the wound interface layer relative to the tissue site, which allows for the debridement of debris that may be located at the tissue site.

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.
