Abstract
Dressings, systems and methods of treating a tissue site are described. A method of manufacturing the dressing can include providing a dressing material. The dressing material can have a surface configured to contact the tissue site. The dressing material can also have a plurality of pores. The method can further include applying a compressive force to the dressing material at an angle to the surface, the compressive force causing permanent deformation of the plurality of pores. Causing permanent deformation of the plurality of pores can comprise forming a plurality of compressed pores. Forming a plurality of compressed pores can include compressing the plurality of pores from a generally circular shape to a generally ovular shape.
Claims28
A dressing for treating a tissue site, the dressing comprising a tissue interface having:
- a first surface configured to face the tissue site;
- a second surface opposite the first surface;
- a thickness extending from the first surface to the second surface;
- a plurality of pores, the plurality of pores having an elliptical shape and a major axis of the plurality of pores being oriented perpendicular to the first surface and the second surface;
- and
- a plurality of holes disposed in the first surface and extending from the first surface toward the second surface to form walls perpendicular to the first surface, a minor axis of the plurality of pores being oriented perpendicular to a surface of the walls of the plurality of holes.
A system for providing negative-pressure therapy to a tissue site, the system comprising:
- a tissue interface comprising:
- a first surface configured to face the tissue site,
- a second surface opposite the first surface,
- a thickness extending from the first surface to the second surface,
- a plurality of pores, each pore of the plurality of pores having an ovoid shape oriented at an angle to the first surface, and
- a plurality of apertures extending from the first surface toward the second surface to form walls perpendicular to the first surface, a minor axis of the plurality of pores being oriented perpendicular to a surface of the walls of the plurality of apertures;
- a sealing member configured to be disposed over the tissue interface to create a sealed space;
- and
- a negative pressure source fluidly coupled to the sealed space.
