  • Patent number: 12281298
    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.

  • Patent number: 12270019
    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.

  • Patent number: 12180456
    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: 20240400970
    Abstract: In some embodiments, a kit for preparing a cell suspension may include a device and a housing. The device may include a first label identifying a first reservoir of the device for use with a first portion of a tissue processing method and a second label identifying a second reservoir of the device for use with a second portion of the tissue processing method. The housing includes a first housing portion configured to store a first set of components associated with the first portion of the tissue processing method. The first housing portion includes a first visual indicator associated with the first label of the device. The second housing portion may be configured to store a second set of components associated with the second portion of the tissue processing method. The second housing portion may include a second visual indicator associated with the second label of the device.

  • Patent number: 11124752
    Abstract: The present invention provides for methods and at least partially automated devices suitable for producing a transplantable cellular suspension of living tissue suitable for promoting tissue regeneration in an epithelium-related procedure, as well as compositions produced therefrom. Tissue regeneration in humans is extremely limited and constitutes a major challenge to the repair of damaged organ function. Wound treatment is a typical area where tissue regeneration is required. Wounds (lacerations or openings) in mammalian tissue can result in tissue disruption and coagulation of the microvasculature at the wound face.
