  • Particulate Acellular Tissue Matrix
    Publication number: 20070078522
    Abstract: A method of processing an acellular tissue matrix to give a particulate acellular tissue matrix includes: cutting sheets of dry acellular tissue matrix into strips; cryofracturing the dry acellular tissue matrix strips at cryogenic temperatures; separating the resulting particles by size at cryogenic temperatures; and freeze drying the fraction of particles desired size to remove any moisture that may have been absorbed to give a dry particulate acellular tissue matrix. Rehydration of the dry particulate acellular tissue matrix may take place just prior to use. The particulate acellular tissue may be applied to a recipient site, by way of injection, spraying, layering, packing, in-casing or combinations thereof.

  • Method for processing and preserving collagen-based tissues for transplantation
    Publication number: 20060210960
    Abstract: A method for processing and preserving an acellular collagen-based tissue matrix for transplantation is disclosed. The method includes the steps of processing biological tissues with a stabilizing solution to reduce procurement damage, treatment with a processing solution to remove cells, treatment with a cryoprotectant solution followed by freezing, drying, storage and rehydration under conditions that preclude functionally significant damage and reconstitution with viable cells.

  • Acellular tissue matrices made from alpa-1,3-galactose-deficient tissue
    Publication number: 20050028228
    Abstract: The invention provides acellular tissue matrices made from collagen-containing tissues of animals genetically modified so as to be deficient in the galactose 1,3-galactose epitope and methods of making and using such acellular tissue matrices.
