A bioabsorbable animal-derived protein matrix [e.g., peptides derived from collagen] designed to provide: 1) a matrix of structural proteins and/or 2) a skin template of living cells [fibroblasts], to facilitate the infiltration/attachment of native cells/tissues (e.g., blood vessels) for wound/skin healing. It is available in various forms [e.g., solution, powder, occlusive/semi-occlusive cover (non-oral)] and may include additional compounds (e.g., alginate, fatty acids). It may be intended to be covered with a secondary dressing. It is commonly intended for treating partial- and full-thickness wounds, ulcers, and draining, surgical, and traumatic wounds. This is a single-use device.
