Abstract: Placental particle (PP) compositions are provided which comprise a mixture of placental particles derived from each of amnion membrane and chorionic membrane, and optionally also umbilical cord. For PP compositions comprising particles of all three of the aforesaid placental tissue types, the PP composition has the following particle size distribution: about 50%-80% of particles from about 5 to about 80 um, about 10%-40% of particles from greater than about 80 to about 150 um, and about 15%-25% of particles greater than about 150 um, based on the total population of placental particles present in the PP composition. The aforesaid PP compositions are applied as a wound covering to provide better (i.e., more thorough and complete) wound coverage than placental particle mixtures without the aforesaid particle size distribution. Methods of making the PP compositions are also provided.

Abstract: 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.

Abstract: 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.

Abstract: A medical implant packaging assembly having an outer tray, an inner tray and a retainer. An implant which may include a hydrated tissue graft may be positioned within the packaging assembly. The inner tray is formed from a moisture barrier material whereby the implant may be maintained in a hydrated state, even if the implant is not immersed in fluid within the packaging assembly, thereby avoiding need for rehydrating steps that are required for dehydrated and/or cryopreserved implants prior to or during surgery. The outer tray and inner tray and a retainer are also made of transparent materials, enabling medical personnel to view the implant through these packaging components prior to and during surgery.

Abstract: 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.

Abstract: The present invention provides concrete-containing compositions, and methods of making and using the same, that allow for the prevention of microbially induced corrosion in concrete. In certain embodiments, the concrete-containing compositions comprise a cementitious substrate, and a formulation of heavy metal-laden, carbon-based sorbent.
