ABSTRACT:
Polymeric sheets having on one or both sides a fabric texture and, optionally, a network of elongated channels in the interior of the structural framework of the sheets. The sheets comprise a plurality of interbonded continuous polymeric ribs extending in a direction parallel to the plane of the sheets. These ribs impart a fabric texture to both sides of the sheets and define between them recessed portions on each surface of the sheets. The elongated channels extend throughout the ribs. The open area between the ribs can vary from zero to 60%. In another embodiment, the sheets have an ultra-thin, pinhole-free polymeric membrane on one side and a fabric texture on the other side. The sheets are useful as burn coverings where they serve as synthetic, temporary replacements for damaged or missing skin. The sheets have physiologic properties similar to human skin, excellent drapability characteristics, recessed portions which provide a reservoir for wound debris and, in certain embodiments, a dermal surface which permits wound adherence by fibrolastic ingrowth.
