Abstract
Wound dressing compositions comprising of a bioresorbable sponge encapsulated within a polysaccharide envelope. The bioresorbable sponge is preferably comprised of collagen and oxidised regenerated cellulose. The outer polysaccharide envelope is preferably comprised of chitosan. The outer polysaccharide envelope functions to modulate the rate at which the bioresorbable sponge breaks down within a wound.
