A method for treating a topical wound of a patient, the method comprising:
- treating a topical wound of a patient by applying to the wound a wound dressing comprising a collagenous biomaterial isolated as a sheet of tissue from urinary tract tissue of a mammal, said collagenous biomaterial comprising tissue mucosa and collagen-containing connective tissue occurring under the tissue mucosa in the urinary tract tissue, wherein the collagen-containing connective tissue has been separated from attached tunica muscularis tissue of the urinary tract tissue, wherein said isolated collagenous biomaterial comprises a growth factor and exhibits the capacity to remodel tissue upon application to the patient, and wherein said isolated collagenous biomaterial has a nucleic acid content of less than 10 micrograms per milligram and a bioburden of less than 2 colony forming units per gram.
