  • Publication number: 20230136935
    Abstract: Disclosed are a method for creating a surgical training model, a surgical training model apparatus, a bone model, an article that emulates tissue of an animal musculoskeletal system, an article that emulates animal fat tissue, and an article that emulates animal skin tissue. One version of the method comprises placing a spinal vertebrae model in a cavity model that emulates an animal body cavity; forming a first layer on top of the vertebrae model, wherein the first layer emulates an animal muscle tissue; placing a second layer over the first layer, wherein the second layer emulates an animal fat tissue; and placing a third layer over the second layer, wherein the third layer emulates an animal skin tissue. The spinal vertebrae model can be 3D printed from a thermoplastic polymer and infiltrated with a foam into an interior space of the 3D printed spinal vertebrae model.

  • Patent number: 11559803
    Abstract: The present invention describes an integrated apparatus that enables identification of migratory cells directly from a specimen. The apparatus only requires a small number of cells to perform an assay and includes novel topographic features which can reliably differentiate between migratory and non-migratory cell populations in a sample. Both the spontaneous and chemotactic migration of cancer cells may be measured to distinguish between subpopulations within a tumor sample. The migratory cells identified using the apparatus and methods of the present invention may be separated and further analyzed to distinguish factors promoting metastasis within the population. Cells in the apparatus can be treated with chemotherapeutic or other agents to determine drug strategies to most strongly inhibit migration. The use of optically transparent materials in some embodiments allows a wide range of imaging techniques to be used for in situ imaging of migratory and non-migratory cells in the apparatus.
