  • Publication number: 20200337719
    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.

  • Publication number: 20200330284
    Abstract: Systems, apparatuses, and methods for closing an opening through a surface of a tissue site are described. The system includes a sealing member adapted to cover the opening to form a sealed space and a negative-pressure source adapted to be fluidly coupled to the sealed space to provide negative pressure to the sealed space. The system also includes a contracting layer adapted to be positioned adjacent the opening and formed from a material having a firmness factor and a plurality of holes extending through the contracting layer to form a void space. The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

  • Patent number: 10792192
    Abstract: According to an illustrative embodiment, a system for treating a wound at a tissue site of a patient comprising a reduced-pressure source to supply reduced pressure, a drape adhering to the tissue site to cover the wound where possible leak passages between the drape and the tissue site may occur, and a seal disposed between the drape and the tissue site, is disclosed. The seal is adapted to react with a fluid to form a sealant substantially filling the passages in response to air leaking through the passages from outside the drape when reduced pressure is applied to the wound. According to another illustrative embodiment, a method for sealing a drape to a tissue site for treating a wound at the tissue site comprising applying the drape to cover the tissue site whereby passages are formed between the drape and the tissue site, positioning a seal between the drape and the tissue site wherein the seal is adapted to react with a fluid to form a sealant for substantially filling the passages, is also disclosed.

  • Publication number: 20200281678
    Abstract: Provided herein is a system and method for mitigating premature light deactivation of light deactivated adhesive drapes. One aspect provides a system comprising a drape, an adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a photochromic layer that may transition between a blocking transmittance state and a non-blocking transmittance state to block or allow certain wavelengths of light to pass through. Some systems may use a combination of a photochromic layer and a filter layer to prevent the adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing one or more of a photochromic layer and a filter layer and applying light to the drape to deactivate the adhesive layer and promote easy, clean, and less painful removal of the drape.

  • Patent number: 10765592
    Abstract: A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.

  • Patent number: 10765783
    Abstract: Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

  • Publication number: 20200237605
    Abstract: A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.
