SurgiMend PRS is a superior, acellular biologic matrix designed specifically for plastic and reconstructive surgery. It is derived from fetal bovine dermis, one of the richest sources of Type III collagen available. Type III collagen mediates tissue healing and growth while inhibiting scarring.SurgiMend PRS is made of pure collagen, has no preservatives, and is free of contaminants, artificial chemical crosslinks, and denatured proteins. It is terminally sterilized - never treated with potentially antigenic antibiotics. As a result, SurgiMend PRS does not elicit a detrimental foreign body inflammatory response upon implantation.
