Abstract
Dressings for closing an opening through a surface of a tissue site are described. The dressing includes a cover adapted to form a sealed space over the opening and a bolster. The bolster is adapted to be positioned adjacent the opening and includes a first plurality of holes. The holes have an average width to length ratio causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. Systems, apparatuses, kits and methods including and/or using the dressing for closing the opening are also described.
Claims23
A dressing for closing an opening through a surface of a tissue site, the dressing comprising:
- a cover adapted to form a sealed space over the opening;
- a bolster having a first surface and a second surface and adapted to be positioned adjacent to the opening, wherein the bolster comprises a first layer defining the first surface, a second layer defining the second surface, the first layer coupled to the second layer, and a first plurality of holes extending through at least a portion of the first layer and the second layer of the bolster, wherein the first plurality of holes have an average width to length ratio less than or equal to 0.50;
- and
- a top layer adjacent to the first surface of the bolster, the top layer comprising a third plurality of holes extending through at least a portion of the top layer, the third plurality of holes substantially adjacent to the first plurality of holes.
A dressing kit comprising:
- a bolster comprising a first surface, a second surface, a first layer defining the first surface, a second layer defining the second surface, the first layer coupled to the second layer, and a first plurality of holes extending through at least a portion of the first layer and the second layer, wherein the holes have an average width to length ratio less than or equal to 0.50 and the bolster has a thickness of less than or equal to 6.0 mm;
- a cover, wherein the cover is separate from the bolster or adjacent to the first surface of the bolster;
- a protective layer comprising a second plurality of holes extending through at least a portion of the protective layer, wherein the protective layer is separate from the bolster or adjacent to the second surface of the bolster and the second plurality of holes are substantially adjacent to the first plurality of holes;
- and
- a top layer, wherein the top layer is separate from the bolster or adjacent to the first surface of the bolster, the top layer comprising a third plurality of holes extending through at least a portion of the top layer, the third plurality of holes substantially adjacent to the first plurality of holes.
A dressing for closing an opening through a surface of a tissue site, the dressing comprising:
- a cover adapted to form a sealed space over the opening;
- a bolster having a first surface and a second surface and adapted to be positioned adjacent to the opening, wherein the bolster comprises a first layer defining the first surface, a second layer defining the second surface, the first layer coupled to the second layer, and a first plurality of holes extending through at least a portion of the first layer and the second layer, wherein the holes have an average width to length ratio 0.050 to 0.50, the bolster has a thickness of 1.0 mm to 6.0 mm, and the bolster comprises a non-woven material or a compressed foam;
- and
- a top layer adjacent to the first surface of the bolster, the top layer comprising a third plurality of holes extending through at least a portion of the top layer, the third plurality of holes substantially adjacent to the first plurality of holes.
