Abstract: Soft tissue supports, soft tissue implants, and methods of making and using soft tissue supports are disclosed. One soft tissue support includes a unitary piece of processed porous tissue material having an anterior portion and a posterior portion. The anterior and posterior portions define a cavity therebetween. The cavity is sized to receive a breast implant therein. The cavity has at least one opening sized to receive the breast implant therethrough. One soft tissue implant includes the soft tissue support and a breast implant positioned within the cavity of the soft tissue support. The implant may further include a soft tissue graft configured to support the processed porous tissue material and the breast implant. A method of using a soft tissue support includes inserting a breast implant into the soft tissue support, and implanting the soft tissue support containing the breast implant in the cavity.

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.

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: Soft tissue grafts, packaged soft tissue grafts, and methods of making and using soft tissue grafts are disclosed. One soft tissue graft includes processed tissue material having first and second opposed surfaces. The first and second opposed surfaces are bounded by first and second edges. The first edge has a concave shape that curves toward the second edge. The second edge has a convex shape that curves away from the first edge. The first surface comprises a plurality of apertures. At least one of the apertures is formed from a multi-directional separation in the first surface. One method of making a soft tissue graft includes positioning a cutting die on a surface of tissue material, pressing the cutting die into the tissue material to cut the tissue material, and processing the cut tissue material to create processed tissue material.

Abstract: The present invention is directed to methods for collecting and processing autografts, processed autografts, kits for collecting and transporting autografts, and tools for preparing autografts. It is also directed to autologous bone grafts, and methods of preparing them.

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: 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 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.
