MuscleMatrix is developing a hydrogel that could change how medics treat traumatic injuries on the battlefield, as well as revolutionize surgical repairs for civilians with soft tissue injuries. The company's patented semi-synthetic hyaluronic acid hydrogel is a structural scaffold that can be prepared as a hydrogel by in situ crosslinking, or as a lyophilized, terminally sterilized microporous dry scaffold for insertion into the injury.
