Soft tissue repair grafts are provided for supporting, covering, and/or retaining an implant positioned in the body of a subject. The grafts are particularly suitable for use for pre-pectoral breast reconstruction with a breast implant or tissue expander. The grafts include positional notches for more accurate positioning in a subject. The grafts also include at least one cuff element which is folded to form a reinforced folded edge for suturing the graft more securely to adjacent tissues than previously known grafts. The grafts also include a plurality of arcuate slots which form a plurality of circular patterns arranged concentrically about a focal point, thereby enabling the grafts to expand without tearing and to conform more closely to the implant and/or adjacent body tissues such as the breast pocket, than previously known grafts. Acellular dermal matrices are particularly suitable for making the soft tissue repair grafts.

A method of preventing or reducing the occurrence and/or development of a hernia within a subject at risk of developing a hernia includes implanting a graft material in contact with an opening in an abdominal wall. The graft material promotes healing of the abdominal wall and includes placental or placental derived tissue.

The present disclosure provides tissue fillers. The tissue fillers can include a plurality of tissue particles formed from acellular tissue matrix fragments. The tissue fillers can be used to fill tissue sites, such as voids formed after tissue resection.

The present disclosure provides anchor bolsters for three-dimensional biologic scaffolds, including related methods of formation and use. The composite bolster-scaffold provides an improved device to securely anchor a three-dimensional tissue scaffold in position relative to surrounding anatomic structures, allowing time for colonization of native cells and subsequent incorporation of the three-dimensional tissue scaffold by the recipient tissue bed.

Methods for treating tissue matrices and tissue matrices produced according to the methods are provided. The methods can include treating select portions of a tissue matrix with a fluid containing at least one agent to produce a tissue matrix with variable mechanical and/or biological properties.

The invention relates to crosslinked soft tissue grafts and methods of use thereof. The invention also relates to methods of preparing the same.

The present invention discloses the method of preparation and use of soft tissue membranous structures into slip resistant membranes with regularly spaced surface projections on one side and concave depressions on the other side with perforations or without perforations which enhance vascular ingrowth and tissue incorporation.

The present application is directed to the field of implants comprising soft tissue for use in implantation in humans. The soft tissue implants of the present application are preferably obtained from xenograft sources. The present application provides a chemical process that sterilizes, removes antigens from and/or strengthens xenograft implants. The present techniques yield soft tissue implants having superior structural, mechanical, and/or biochemical integrity. The present application is also directed to processes for treating xenograft implants comprising soft tissues such as dermis, and to implants produced by such processes.

Disclosed herein are muscle implants and methods of making muscle implants comprising one or more decellularized muscle matrices. The muscle matrices can, optionally, be joined to one or more decellularized dermal matrices. The muscle implants can be used to enhance muscle volume or to treat muscle damage, defects, and/or disorders. The decellularized muscle matrices in the implants retain at least some of the myofibers found in a muscle tissue prior to processing.

Particulated and reconstituted tissues comprising small, densely packed tissue microparticles encapsulated in a tissue specific promoting gel packed at a percolation threshold that can be transplanted into damaged tissue thereby facilitating regeneration following trauma to the tissue. The engineered microparticle construct for tissue replacement and repair, as taught herein, provides numerous benefits including (1) encouraging a regenerative response in damaged tissue regions, (2) mimicking the structural support of native tissue, (3) establishing an environment that promotes attachment, migration, and differentiation of infiltrating stem cells, and (4) providing a source of growth factors and other anti-catabolic growth factors and cytokines. Tissue specific microparticles packed together at, or past, their percolation threshold will provide the necessary mechanical environment and to best recapitulate and integrate with native tissue. The packing of microparticles, derived from the ECM of native tissue, to a concentration past the percolation point will yield both the necessary biochemical and biomechanical properties necessary for reconstituting a specific tissue.
