Abstract: The invention relates to medical implants, including spinal implants and bone grafts, for fixation and integration with hard tissue. The bone medical implants include at least one rotational fixation mechanism that further includes or is attached to one or more sharp protrusions configured to penetrate and become lodged into hard tissue to provide support and positional stability. Such support is useful to ensure that the spinal bone graft may be used without additional stabilizing or anchoring structures, such as supporting plates or screws.

Abstract: A spinal bone graft includes one or more cortical bone portions forming a first unit. The first unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms at least one first undercut. The bone graft also includes one or more cortical bone portions forming a second unit. The second unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms either at least one second undercut, or at least one connector. In the former, at least one connector is received in each of the first and second undercuts to interconnect the first and second units. In the latter, the at least one connector of the second unit is received in the first undercut of the first unit to interconnect the first unit and second unit.

Abstract: The present invention provides demineralized bone fibers exhibiting optimal handling properties (e.g., high moldability and low elastic modulus) and biological activities (e.g., osteoinductivity) as well as non-demineralized bone fibers useful for preparing the demineralized bone fibers. A well-controlled demineralization process for preparing the demineralized bone of fibers is also provided. Products comprising the demineralized bone fibers and uses thereof are further provided.

Abstract: An improved packaging assembly for storing, distributing, treating, mixing, and dispensing tissue and/or cellular material and/or implantable material. The packaging assembly may include pouches, tubes, and a bag made of a sealable, flexible polymeric material that is open at one end and a needle-free swabable connector attached to the pouch at the other end and acting as a port to allow for the introduction or discharge of biological solutions, rinsing solution, and/or preservation solutions into the packaging assembly. The designed thickness of the wall of the packaging assembly facilitates efficient heat/cold transfer, which is useful for successful controlled rate freezing, quick thawing, and resuscitation of viable cells or tissue. The packaging assembly is also useful for combining additional biological fluids with the cellular material or tissue, and for efficient mixing of the biological fluids with the tissue and/or cellular material in the assembly.

Abstract: The present invention provides a cannula for delivering a tissue graft to a treatment site. The cannula comprises a distal end, a proximal end, a bore formed by an interior surface of the cannula, extending from the distal end to the proximal end and having a diameter, and a tissue graft inside the bore and in contact with the interior surface. The tissue graft may be released from the cannula at the distal end to the treatment site. The tissue graft may have a final loading pressure of 20-200 psi. Also provided is a delivery system comprising the cannula and a delivery device. Further provided are methods for delivering a tissue graft in a cannula to a treatment site and methods for preparing a cannula loaded with the tissue graft.

Abstract: The present invention provides a product comprising plated human hepatocytes on a surface and at least some of the plated hepatocytes are in one or more hepatocyte clusters on feeder cells, which are attached to the surface. A method of preparing plated human hepatocytes is also provided. The preparation method comprises applying human hepatocytes to a surface in the presence of feeder cells, co-culturing the applied hepatocytes with the feeder cells, and forming one or more hepatocyte clusters by the co-cultured hepatocytes on the feeder cells, which are attached to the surface. The plated hepatocytes may be used for various purposes, including the preparation of a hepatitis B virus (HBV) infected hepatocyte culture model and drug testing.
