  • Patent number: 10258779
    Abstract: A wound dressing has a micro-architecture to produce appropriate strains in cells to promote the healing a wound. The apparatus includes a wound cover for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound, a vacuum source in fluid communication with the reservoir and suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound, and a porous structure positioned in contact with the wound for delivering micro-mechanical forces to localized areas of the wound. The porous structure comprises a three-dimensional film material having directional apertures formed therein.

  • Publication number: 20170252545
    Abstract: A wound dressing has a micro-architecture to produce appropriate strains in cells to promote the healing a wound. The apparatus includes a wound cover for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound, a vacuum source in fluid communication with the reservoir and suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound, and a porous structure positioned in contact with the wound for delivering micro-mechanical forces to localized areas of the wound. The porous structure comprises a three-dimensional film material having directional apertures formed therein.

  • Publication number: 20130172834
    Abstract: An apparatus for promoting the healing of an exuding wound includes a wound cover for defining a reservoir over a wound in which a negative pressure may be maintained. The cover may form a substantially fluid-tight seal around the wound and permit fluid communication between the reservoir and a vacuum source suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound. A wound filler positioned between the wound and the wound cover includes a nonwoven material at least partially perforated by sonic welding.

  • Patent number: 8162907
    Abstract: A method of bridging from a wound dressing to a wound port for negative pressure wound therapy includes positioning an elongate wick between a wound and a remote location with respect to the wound. The elongate wick includes a three-dimensional spacer fabric having an upper fabric layer spaced from a lower fabric layer by an intermediate layer of pile threads. The elongate wick is covered with a flexible wick cover such that an enclosure is formed around the elongate wick. A substantially fluid-tight seal is established between a first end of the elongate wick cover and the wound dressing such that a reservoir is defined over the wound in which a negative pressure may be maintained. A substantially fluid-tight seal is established between a second end of the elongate wick cover and a fluid port configured for connection to a source of negative pressure.
