  • Patent number: 11779610
    Abstract: Methods are provided for treatment of several conditions of one or more body features, where the method comprises implanting an acellular soft tissue-derived matrix in, on, proximate to, or a combination thereof, the body feature, wherein the acellular soft tissue-derived matrix comprises a delipidated, decellularized adipose matrix. The delipidated, decellularized adipose tissue matrix is produced by delipidating an adipose tissue sample, followed by decellularizing the delipidated adipose tissue sample. The resulting matrix contains a proportion of lipids which is less than the proportion of lipids contained in a matrix produced by decellularizing an adipose tissue sample prior to delipidating. The delipidated, decellularized adipose matrix may be provided as particles, a slurry, a paste, a gel, an injectable form, or in some other form.

  • Patent number: 11191788
    Abstract: An acellular soft tissue-derived matrix suitable for use as a medical graft or implant may comprise, for example, a delipidated, decellularized adipose tissue matrix. The delipidated, decellularized adipose tissue matrix is substantially free of substances that pose a significant risk of causing an immunogenic response in a patient receiving the matrix. Methods for producing the delipidated, decellularized adipose tissue matrix include the steps of delipidating an adipose tissue sample, followed by decellularizing the delipidated adipose tissue sample. The resulting delipidated, decellularized adipose tissue matrix contains a proportion of Type IV collagen which is greater than the proportion of Type IV collagen contained in a matrix produced by decellularizing an adipose tissue sample prior to delipidating.

  • Publication number: 20200171094
    Abstract: An acellular soft tissue-derived matrix includes a collagenous tissue that has been delipidated and decellularized. Adipose tissue is among the soft tissues suitable for manufacturing an acellular soft tissue-derived matrix. Exogenous tissuegenic cells and other biologically-active factors may be added to the acellular matrix. The acellular matrix may be provided as particles, a slurry, a paste, a gel, or in some other form. The acellular matrix may be provided as a three-dimensional scaffold that has been reconstituted from particles of the three-dimensional tissue. The three-dimensional scaffold may have the shape of an anatomical feature and serve as a template for tissue repair or replacement. A method of making an acellular soft tissue-derived matrix includes steps of removing lipid from the soft tissue by solvent extraction and chemical decellularization of the soft tissue.

  • Patent number: 8557581
    Abstract: The present invention is a process for preparing soft tissue such as tendons, ligaments, cartilage, fascia, dermis, human valves and human veins for implant in a human and removes cellular components and forms an decellular matrix having as major components collagens and elastins while sterilizing the tissue. The process comprises the following steps: (1) isolating from a suitable donor a desired soft tissue sample of the biological material; (2) processing and decellularizing the soft tissue including inspection for visual defects, trimming and soaking the tissue in a detergent depending on whether the tissue is fascia or dermis and rinsing same with sterile water; (3) sterilizing the soft tissue in a vacuum and soaking the tissue in an antibiotic composition or peracetic acid depending on whether the soft tissue is fascia or dermis and rinsing same; (4) processing the tissue by cutting the tissue to size and perforating the tissue; and (5) dipping the tissue in 70% ethanol and packaging the tissue.
