摘要:
The present invention is directed to wound dressings that include a substrate for contacting and/or covering a wound, where the substrate includes a wound-contacting surface, and which substrate contains or is fabricated at least in part from a biocompatible, aldehyde-modified, regenerated polysaccharide, preferably a biodegradable polysaccharide, and to methods of providing coverage and protection of a wound, which method includes applying to a wound the wound dressing of the present invention.
摘要:
The present invention is directed to a hemostatic wound dressing that utilizes a fibrous, fabric substrate made from carboxylic-oxidized cellulose and containing a first surface and a second surface opposing the first surface, the fabric having flexibility, strength and porosity effective for use as a hemostat; and further having a porous, polymeric matrix substantially homogeneously distributed on the first and second surfaces and through the fabric, the porous, polymeric matrix being made of a biocompatible, water-soluble or water-swellable cellulose polymer, wherein prior to distribution of the polymeric matrix on and through the fabric, the fabric contains about 3 percent by weight or more of water-soluble oligosaccharides..

摘要:
A multilayered fabric comprising a first absorbable nonwoven fabric and a second absorbable woven or knitted fabric. Suitably, the first fabric is a polylactide/polyglycolide nonwoven fabric. Suitably, the second fabric is an oxidized regenerated cellulose fabric. Suitably, the first fabric is formed from crimped staple fibers is bonded directly to the second fabric by needlepunching or the like.
