Abstract
Wound dressings and wound inserts comprising a porous film layer and at least a channel, wound inserts of forming wound inserts comprising a porous film layer and at least a channel, and wound-treatment wound inserts.
Claims16
A method of manufacturing a wound insert comprising:
- obtaining an open-celled reticulated foam member having a first surface, a second surface, and a thickness between the first and the second surface;
- felting the first surface of the foam member to form a felted layer;
- and
- removing a portion of the felted layer from the first surface to form at least one channel in the felted layer, the at least one channel being configured to communicate fluid from a wound and to deliver fluid to the wound.
1 more element
A wound insert comprising:
- an open-celled reticulated foam member comprising:
- a first surface and a second surface, the first surface comprising a porous film layer configured to allow passage of negative pressure to a wound site and to inhibit tissue ingrowth;
- a thickness between the first and the second surface;
- the porous film layer comprising a film thickness;
- and at least one channel formed in the porous film layer and comprising a channel depth equal to or greater than the film thickness.
2 more elements
A method of manufacturing a wound insert, comprising:
- felting a surface of an open-celled reticulated foam member to form a felted layer extending into the foam member from the surface;
- and
- removing a portion of the felted layer from the surface to form at least one channel in the felted layer.
