Abstract
Body tissue and structures in an airway may be treated with an artificial scab comprising an inhomogeneous, uncohesive, solid sheet-like body comprising a granular mixture of chitosan and polysaccharide particles. The artificial scab breaks apart into smaller pieces if peeled away from the surgical site or wound, thus reducing the risk of airway occlusion.
