  • Patent number: 8067149
    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.
    Type: Grant
    Filed: June 7, 2002
    Date of Patent: November 29, 2011
    Assignee: LifeCell Corporation
    Inventors: Stephen A. Livesey, Anthony A. del Campo, Abhijit Nag, Ken B. Nichols, Edward S. Griffey, Christopher Coleman

  • Patent number: 6194136
    Abstract: This invention relates to methods, apparatus and solutions for cryopreserving microscopic biological materials for biologically extended periods of time. The method comprises treating a suspension of biological material, in an appropriate buffer, with a cryoprotectant or combination of cryoprotectants which raises the glass transition temperature range of the sample. One or more dry protectants may be added to the cryosolution. The cryosolution is then nebulized and rapidly cooled with novel apparatus, dried by molecular distillation, stored and then rehydrated in a buffer prior to its use. The solutions comprise novel mixtures of cryoprotectants.

  • Patent number: 5154007
    Abstract: This invention relates to an apparatus and method for distillation drying of one or more biological samples. The drying apparatus includes a retaining assembly, a vacuum assembly, cooling means, monitoring means and control means for actively regulating the temperature and pressure conditions of biological tissue so that such tissue may be dried without substantial ultrastructural damage.
