NANOCOMPOSITE SURGICAL MATERIALS AND METHOD OF PRODUCING THEM

摘要

Nanocomposite surgical materials, such as cements, having very fine heterogenous structure are formed by incorporating into a polymeric matrix a well dispersed solid, liquid or gaseous filler having an average mass diamet er ranging from about 750 nanometers to about 1 nanometer. The average ligament thickness of the surgical composite cements ranges from about 750 nanometers to about 1 nanometer. Methods and apparatus for avoiding air contact during the preparation and transfer of a cement to an in vivo side are described.
