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.
Claims22
A method of manufacturing a dressing for treating a tissue site, the method comprising:
- providing a dressing material having a first surface configured to contact the tissue site, a second surface opposite the first surface, and a thickness extending from the first surface to the second surface, the dressing material having a plurality of pores;
- applying a compressive force to the dressing material at an angle to the first surface, the compressive force causing a permanent deformation of the plurality of pores so that the plurality of pores have an elliptical shape with a major axis of the plurality of pores oriented perpendicular to the first surface and the second surface;
- and
- forming a plurality of holes in the first surface that extend from the first surface toward the second surface, the plurality of holes forming 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 tissue interface for treating a tissue site, the tissue interface formed by a process comprising:
- providing a dressing material having a first surface configured to contact the tissue site, a second surface opposite the first surface, and a thickness extending from the first surface to the second surface, the dressing material having a plurality of pores;
- felting the dressing material at an angle to the first surface and causing a permanent deformation of the plurality of pores so that the plurality of pores have an elliptical shape with a major axis of the plurality of pores oriented perpendicular to the first surface and the second surface;
- and
- forming a plurality of holes in the first surface that extend from the first surface toward the second surface, the plurality of holes forming 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.
