Tissue derived porous matrices for treating wounds are provided, as well as methods for making and using them. The tissue derived porous matrices comprise processed tissue of any of several types, such as dermis, adipose, etc., and have a plurality of interconnected pores which allow fluid flow through the matrices. The tissue derived matrices are biocompatible resorbable matrices which remodel with native tissue and facilitate and enhance cell infiltration and tissue ingrowth into the matrices during the wound healing process, thereby enhancing wound healing and tissue remodeling when implanted into a patient. The tissue derived matrices are useful with reduced or negative pressure wound healing methods and systems, without the need to repeatedly revisit the treatment site and remove previously implanted matrices.

Tissue derived porous matrices and methods for making and using same

Methods and compositions for preparing and priming a tissue graft for an accelerated therapeutic effect are provided herein. In one embodiment, the method includes obtaining a tissue containing viable cells from a donor, wherein the viable cells are endogenous to the tissue and remain resident in the tissue; and priming the viable cells with one or more stimuli comprising simulated hypoxia to produce a primed tissue, wherein when grafted to a recipient the primed tissue provides a benefit compared to non-primed tissue.

Methods and compositions for preparing transplant tissue

Tissue graft retainer

A tissue graft container is provided having an interior space and including a vent which allows fluid (liquid and vapor) to escape from the container during drying of the tissue graft. The vent may be one or more apertures, one or more elongated openings, or a combination thereof, through one or more components of the container. A tissue graft packaging system having a retainer including first and second members with respective first and second pluralities of channels, and configured to removeably interconnect the first and second members in a closed configuration. The first and second pluralities of channels create a continuous interior space. The retainer further includes a vent, such as apertures, slits, etc., through one or both of the first and second retainers, for allowing moisture to escape from the retainer during the drying of a tissue graft contained within the continuous interior space of the retainer.

Packaging system for tissue grafts

A cutting device is provided having multiple evenly-spaced cutting blades and which is useful for producing tissue forms comprising membranous tissue fragments which are relatively uniformly sized and shaped. The present invention also relates to methods for using the cutter device to quickly and efficiently produce such tissue forms which are useful as grafts and can be flowable and easily passable through a luer-slip tip syringe or needle.

Multi-blade cutting device

Methods and compositions for preparing and priming a tissue graft for an accelerated therapeutic effect are provided herein. In one embodiment, the method includes obtaining a tissue containing viable cells from a donor, wherein the viable cells are endogenous to the tissue and remain resident in the tissue; and priming the viable cells with one or more stimuli to produce a primed tissue, wherein when grafted to a recipient the primed tissue provides a benefit compared to non-primed tissue.

A tissue graft packaging system having a retainer including first and second members with respective first and second pluralities of channel sidewalls that define first and second pluralities of channels, and first and second engagement means configured to removeably interconnect the first and second members. The first and second pluralities of channel sidewalls are configured to create a continuous interior space between the first and second members. A tissue graft, such as a cryopreserved viable tissue graft, is contained within the continuous interior space of the retainer. Processes for packaging, thawing and rinsing the tissue graft using the tissue graft packaging system and its retainer are also disclosed.
