  • Publication number: 20180071102
    Abstract: This invention is directed to an assembled implant comprising two or more portions of bone that are held together in appropriate juxtaposition with one or more biocompatible pins to form a graft unit. Preferably, the pins are cortical bone pins. Typically, the cortical pins are press-fitted into appropriately sized holes in the bone portions to achieve an interference fit. The bone portions are allograft or xenograft.

  • Patent number: 9332750
    Abstract: This invention is a novel method for perfusion of a porous implant which achieves efficient interpenetration of desired factors into and removal of undesirable factors from the pores of the implant, cleaning of the implant, efficient passivation of the implant (inactivation of pathogens, microorganisms, cells, viruses and the like and reduction in antigenicity thereof), and the novel implant produced by such treatment. The process presents a system wherein the rate of pressure cycling, the fact of pressure cycling, and the amplitude of pressure cycling, results in highly cleaned tissues and other implants for implantation.

    Abstract: A method for perfusion of a porous implant which achieves efficient interpenetration of desired factors into and removal of undesirable factors from the pores of the implant, cleaning of the implant, efficient passivation of the implant, and the implant produced by such treatment. A system wherein the rate of pressure cycling, the fact of pressure cycling, and the amplitude of pressure cycling, results in highly cleaned tissues and other implants. Goals include between about a one to twelve log reduction in bacterial contamination, between about a one to fifteen log reduction in enveloped virus contamination, up to about a five log reduction in non-enveloped virus contamination, between about a two to tenfold reduction in endotoxin, maintenance of implant or graft biologic and biomechanical properties, absence of tissue toxicity due to cleaning solutions used, and reduced implant antigenicity.
