G4Derm / G4Derm Plus Synthetic Wound Matrix is a sterile, biodegradable hydrogel matrix supplied in a prefilled syringe ready for topical use as primary wound dressing, with or without the use of an optional nozzle. The hydrogel in G4Derm / G4Derm Plus is composed of an aqueous solution of synthetic peptide (≥ 98% sterile water). The device is completely non-animal tissue and non-cellular derived. G4Derm / G4Derm Plus forms a three-dimensional hydrogel scaffold, which, at a basic structural level, is composed of a matrix of interwoven fibrils formed from individual peptide monomers. This woven network structure, or matrix barrier, is similar to the microarchitecture of endogenous extracellular matrix ("ECM"). This structure also functions as a matrix that holds and donates water to underlying tissue, while providing an effective barrier to cover and protect the wound against the external environment, namely against bacterial penetration. G4Derm / G4Derm Plus Synthetic Wound Matrix forms a clear, biodegradable hydrogel without expansion in volume. During dressing changes, the unincorporated or unintegrated material may be removed without causing trauma to the underlying tissue by gently flushing / wiping the wound.
