Abstract

A wound contact device comprising a permeable material and a wound contact layer having voids extending through the contact layer to. a depth in the permeable material. The wound contact layer can comprise a thin sheet or film forming a generally flat and smooth wound contact surface having essentially no discontinuities or gaps. The wound contact layer can comprise a thin sheet of highly calendered fabric forming a wound contact surface having a mean surface roughness in the range of about O microns to about 200 microns. In progressive wound healing, an embodiment of the wound contact device having the fabric contact surface is used in earlier healing stages and an embodiment of the wound contact device with film contact surface is used in later healing stages. The wound contact device is particularly useful in wound dressings for use in suction-assisted wound therapy.
