  • Publication number: 20250049559
    Abstract: Allografts for soft tissue repair, including breast reconstruction and other plastic surgery procedures, are disclosed. In an exemplary embodiment, first and second cuts are made into the reticular layer of a skin sample to separate an improved acellular dermal matrix (ACDM) which forms a dermal tissue form useful as a graft. The dermal tissue form consists essentially of reticular dermis and has a first exposed surface formed by reticular dermis, an opposite second exposed surface formed by reticular dermis, and has substantially uniform density and uniform porosity between the first and second exposed surfaces, which allows and promotes rapid and efficient cellular ingrowth and tissue ingrowth substantially equally from either the first or second exposed surfaces upon implantation.

  • 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.
