  • Patent number: 6758865
    Abstract: A method for preparing a soft tissue xenograft includes the steps of removing at least a portion of a soft tissue from a non-human animal to provide a xenograft; washing the xenograft in saline and alcohol; subjecting the xenograft to cellular disruption treatment; and either digesting the xenograft with a glycosidase or glycosidase digestion followed by treatment for sialylation.

  • Publication number: 20030039678
    Abstract: The invention provides for the use of an improved xenograft bone particulate with respect to osteo-integration and bone remodeling, while diminishing the primate-to-pig immunological response using established bone-processing technique. Work was carried out using undecalcified bone to determine immunocompatibilty and bone remodeling potential of processed porcine bone struts following onlay graft implantation. New bone formation was evident, including the infiltration of cellular materials responsible for fusion and bone reconstruction.
