Three-dimensional porous film contact layer with improved wound healing

A therapeutic apparatus to promote healing of a wound comprising:

• a wound cover for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound;
• a vacuum source configured to be in fluid communication with the reservoir, the vacuum source suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound;
• and
• a three-dimensional film material configured to be in contact with the wound, the three-dimensional film material having a plurality of passages defined between a male face and an opposite female face thereof;
• wherein the three-dimensional film material is configured to be positioned such that the male face is in contact with the wound.
