US Patent 10420794 Polysaccharide particle mixture

Tissue and other body structures may be protected using a dry, free-flowing, sterilized mixture of chitosan particles and oxidized polysaccharide particles in sealed packaging. The mixture may assist in returning an injured, inflamed or surgically repaired surface to a normal state, e.g., through one or more healing mechanisms such as modulation of an inflammatory response, phagocytosis, mucosal remodeling, reciliation or other full or partial restoration of normal function.
