An apparatus for promoting scar-free healing at a tissue site where negative pressure is applied, the apparatus comprising:
- a tissue contact layer comprising silicone and an open area in an amount sufficient to inhibit scar tissue formation when negative pressure is applied at the tissue site.
A method for the treatment of a wound, comprising:
- providing a wound dressing comprising a silicone wound contact layer and a moisture vapor permeable cover layer;
- positioning the dressing over a wound site to form a sealed cavity over the wound site;
- and
- applying negative pressure to the wound site so as to draw fluid from the wound site into the sealed cavity.
A method for promoting scar-free healing at a tissue site where negative pressure is applied, the method comprising:
- locating a wound dressing at a tissue site, the wound dressing comprising a tissue contact layer comprising silicone and an open area in an amount and proportion sufficient to at least reduce scar tissue when negative pressure is applied at the tissue site;
- applying negative pressure to the tissue site via the wound dressing;
- and
- at least reducing scar tissue at the tissue site.
