Abstract
The present invention provides a polymer delivery system for the in vivo binding and release of growth factors, preferably orthobiologic GF, comprising a hyperbranched polymer having physiologically-acceptable anionic phosphorous groups. The hyperbranched polymer is preferred to be a polyurea with phosphonate anions. This polymer can be cross-linked to form a network and provide a coating for implanted devices.
