  • Publication number: 20240209307
    Abstract: One or more systems for automated preparation of a regenerative epidermal suspension comprises a base unit, a cartridge assembly containing a cup, and a tissue disaggregator. The system may also include related tools. The system executes one or more sequences wherein a first motor actuates the pestle against a tissue sample that is disposed along a screen within the cup while the tissue sample is in contact with, in sequence, an enzyme solution, a first buffer solution, and then a second buffer solution. To transition between fluidic contact stages or steps, the tissue disaggregator engages with and lifts the cup into a raised position within a processing area of the cartridge while a base plate motor rotates the appropriate well into alignment under the cup for each processing step. Once the sequence is complete, a user may draw up a regenerative epidermal suspension through an opening in the cartridge top cover.

  • Publication number: 20240207841
    Abstract: One or more methods for automated preparation of a regenerative epidermal suspension comprises a processor receiving an initiation signal that indicates that a cartridge that has a cover, a cup containing a tissue sample, and a well plate situated beneath the cover that has a first well containing an enzyme solution and a second well containing a buffer solution, has been placed on a sensor, executing a sequence that actuates a tissue disaggregator against the tissue sample in the cup positioned in the first well, raises the cup to an upper position, rotates the well plate to position the second well beneath the cup, lowers the cup to a position within the second well, and actuates the tissue disaggregator against the tissue sample in the second well.

  • Publication number: 20240209296
    Abstract: One or more methods for treating a tissue site comprises collecting a tissue sample that has keratinoytes and placing the tissue sample in a cartridge that has a well plate, positioning the cartridge within a base unit that has a tissue disaggregator, activating the base unit to rotate the well plate to align wells in the well plate with the tissue sample and the tissue disaggregator, operate the tissue disaggregator to separate the tissue sample to form a regenerative epidermal suspension, and provide the regenerative epidermal suspension to a tissue site to enhance healing of the tissue site.

  • Publication number: 20240209299
    Abstract: One or more cartridges for preparation of a regenerative epidermal suspension comprises a cover with a raised processing opening, a cup that can be received within the raised processing opening and has a screen, and a well plate that is positioned under the cover, has a well, and rotates relative to the cover such that the well aligns with the raised processing opening. One or more cartridges for preparation of a regenerative epidermal suspension comprises a cover with an opening that can receive a tissue sample.
