The present application relates to use of transglutaminases to treat various products, including medical devices such as tissue grafts, tissue matrices or other tissue-derived materials, and synthetics. The transglutaminases can be applied to the medical devices to provide advantages such as adhesion resistance or abrasion resistance.

Polyurethane-based tissue fillers useful for treating and/or augmenting tissue, as well as acting as a biological scaffold that promotes cell in-ingrowth and tissue integration, are disclosed, as are quick-setting, injectable precursors of such tissue fillers. Such tissue fillers generally comprise (1) a polyurethane and (2) a particulate acellular tissue matrix. Also disclosed are methods of treating and/or augmenting tissues using such tissue fillers, particularly voids in human tissue such as anal fistulae or hernias.

The present disclosure provides devices and methods for treating breasts. The devices can include an acellular tissue matrix having a predefined shape that allows for complete or enhanced coverage of an anterior portion of a breast implant or tissue expander or to support an implant and/or surrounding tissues.

Graft materials and devices for surgical breast procedures may include a sheet of biocompatible material and a plurality of fenestrations distributed across a portion of the sheet of biocompatible material. The sheet of biocompatible material can have a first axis and a second axis coincident with the sheet of biocompatible material. The sheet of biocompatible material can also have a first edge that intersects the second axis and a second edge that intersects the second axis. The first axis can be orthogonal to the second axis. The plurality of fenestrations can be distributed across a portion of the sheet of biocompatible material closer to the first edge than the second edge. Other apparatuses and methods are disclosed.

The present disclosure provides tissue matrix packaging devices and methods of use. The packaging can be used to help a tissue matrix sample retain its shape when being stored or transported.

The present disclosure provides meshed acellular dermal tissue matrix compositions, devices, and methods of use. The meshed devices can be used in conjunction with a variety of implants such as breast implants or tissue expanders.

The present disclosure provides tissue products produced from extracellular tissue matrices. The tissue products can include acellular extracellular matrices that have been treated in select areas to increase the compressive modulus of the matrix in the selected area while maintaining the ability to support cell growth and tissue regeneration. In addition, the tissue products can include collagen-containing materials that support tissue ingrowth along with a framework of collagenous or polymeric materials such that the combination has a desired compressive or tensile modulus and/or strength while maintaining the ability to support cell growth and tissue regeneration.

The present application relates to injectable tissue products and their production and use thereof. The tissue products include a group of acellular tissue matrix particles, a bioadhesive, and a biocompatible polymer. The tissue products may be used to treat hernia defects.

The present disclosure provides tissue products produced from extracellular tissue matrices. The tissue products can include acellular extracellular matrices including combinations of different tissue types. The combination can harness various properties of the different tissues to provide improved composite structures with desired mechanical and/or biologic properties.

The present disclosure provides tissue products produced from adipose tissues, as well as methods for producing such tissue products. The tissue products can include acellular extracellular matrices. In addition, the present disclosure provides systems and methods for using such products.
