  • Publication number: 20240066183
    Abstract: A wet human or other tissue product may be packaged with a primary and secondary backing. The primary backing may cover a larger area of the tissue than the secondary backing, and the primary backing may be removed first during application of the tissue to a patient, either by sliding or peeling the primary backing away. The secondary backing may assist in holding the tissue in place while the primary backing is removed. The primary backing may provide mechanical support and keep the tissue spread during packaging, handling, and application to a patient. The tissue assembly with primary and secondary backing may be stored in a heat sealed, sterile flat pouch with preservation media. The packaged assembly may include a port for introducing preservation media. A use case for the packaging includes wet, undried amniotic membrane.

  • Publication number: 20230250396
    Abstract: A mesenchymal stem cell harvesting system and method for increasing the efficiency of collecting and processing physiological fluids containing mesenchymal stem cells from a cavity within a patient's skeletal system. Microenvironments risk in MSC production and concentration within a cavity, for example the patient's ilium, are penetrated with a pointed instrument used to create an aperture in the hard cortical bone forming the cavity followed by the insertion of an aspiration device which extracts one or more samples of cancellous bone, bone marrow, bone marrow blood and other aspirated material. The aspirate is rinsed and may be filtered to remove unwanted material and to increase the concentration and purity of the mesenchymal stem cells in the aspirant far beyond levels formerly obtainable for use in autologous treatment of the patient.

  • Patent number: 11253548
    Abstract: A method of producing the constituents of a therapeutic product from mammalian cells is described herein. Cells are isolated from a mammalian source. The cells are exposed to supercritical carbon dioxide (SCCO2) for 1 to 30 minutes, where the SCCO2 is maintained at a pressure of 1071 pounds per square inch (PSI) and a temperature of 31.1 to 45 degrees Celsius during the exposure. The exposure dissociates the cellular membranes of the cells to release intramembrane components therein to produce constituents of the therapeutic product. The mammalian cells may include at least one of platelets, stem cells, germ cells, and somatic cells. The methods described herein are particularly advantageous for releasing and capturing therapeutic intramembrane components from platelets and alpha-granules.

  • Publication number: 20210080358
    Abstract: A system for collecting and processing a sample of an enriched population of mesenchymal stem cells in a matrix of body tissue in which the sample is separated into smaller segments to optimize the ability of the system to organize the stem cells into small working clusters with tissue. The tissue clusters are separated into optimized groupings for further processing and use in medical procedures.

  • Publication number: 20200199512
    Abstract: An acellular product may be derived from human placenta and may be used in various scenarios for wound healing. Because the product may be acellular, the product may be processed for storage and transportation with minimal degradation. The product may include various scaffolding such as biomaterials or human tissue, and the scaffolding may be infused with various plasmas and agents. The cell-free treatment may maintain the biological activity of many therapeutic agents found within cells and may possess multiple structural components to support cellular attachment. The structural components or scaffolds may function as a reservoir of highly diffusible chemotactic and cellular-programming factors that may be useful to treat injury and disease. In many cases, fibrinogen may be absent, which may reduce scarring.

  • Publication number: 20190025162
    Abstract: Apparatus, systems and methods for processing a blood sample. One embodiment includes an isolation container having at least one sidewall defining an interior volume. The interior volume includes a medial reservoir in fluid communication with proximal and distal reservoirs. The diameter of the medial reservoir is less than the diameter of the proximal and distal reservoirs. Therefore, the isolation container has an interior volume which is roughly hour-glass shaped with the medial reservoir being a substantially narrowed portion or channel between two wider portions. The isolation container is configured such that the buffy coat layer of fractionated blood will be located within, or may be manipulated to be with the medial reservoir.
