Abstract
Certain embodiments described herein are directed to an elongated layer of material and a lip to be placed in contact with a wound and the elongated layer of material to be wrapped around a wound filler, their methods of use and systems incorporating the same, wherein the wound filler lip is configured to be positioned beneath the fascia. Additionally, some embodiments described herein are directed to the closure of the wound and the use of attachment mechanisms on the elongate layer and lip to attach to the wound surface.
Claims30
An apparatus for wound treatment, comprising:
- an annular shaped layer of material configured to be placed in contact with a wound of a patient, the annular shaped layer of material having an annular opening;
- a lip extending outwardly from the annular shaped layer of material, wherein the lip is shaped and sized for positioning beneath tissue surrounding the wound of the patient;
- and
- a wound filler extending in a z direction between a top and a bottom and extending in an x-y plane between opposing wound edges of the wound, the wound filler is configured to preferentially contract in a first x-direction in the x-y plane relative to a second y-direction within the x-y plane upon application of negative pressure to the wound, and
- wherein the wound filler transmits negative pressure to apply a closure force on the wound in the x-direction.
