Patent 7135042 was granted and assigned to HFSC on November, 2006 by the United States Patent and Trademark Office.
A surgical implant (1) in the form of an intervertebral implant defines a cavity (2) designed to receive bone replacement materials. The bone replacement material is entirely synthetic. With the surgical implant of the present invention, the danger of infection attending a natural bone replacement material is eliminated and, by selecting a synthetic bone replacement material, its physical properties (porosity, pore size, mechanical strength) are no longer exposed to fluctuations.
