  • Patent number: 10932464
    Abstract: The invention is 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 invention 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.

  • Patent number: 10857000
    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.

  • Publication number: 20200239839
    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.

  • Patent number: 10653462
    Abstract: A pin made of cortical bone may be inserted into adjoining bones of a toe to align and secure the bones. The pin may have barbs to prevent migration of the pin. The pin may include a shoulder to further prevent migration of the pin from the bones, to increase the strength of the pin, and to increase the surface area between the bone pin and the host bone. The pin may further include flattened portions on its circumference to aide in rotating the pin during insertion. The pin may be treated to reduce brittleness.
