  • Patent number: 11883653
    Abstract: An electroporation device with a needle array removably attached thereto, the needle array having a body, a shroud movable with respect to the body between a rest position and one or more actuated positions, and an auto-lock assembly. Where the auto-lock assembly is adjustable between a locked configuration, where the shroud is not movable with respect to the body, and an unlocked configuration, where the shroud is movable with respect to the body, and where biasing the shroud from the rest position to the one or more actuated positions and back to the rest position adjusts the auto-lock from the unlocked configuration to the locked configuration.

  • Publication number: 20220184378
    Abstract: An electroporation device having a battery pack including a plurality of battery cells and at least one lead in electrical communication with a circuit board. The battery pack including a safety switch and a controller for selectively placing the battery cells in electrical communication with the one lead. Where the controller is in operable communication with the safety switch such that when the controller detects one or more operating conditions the controller instructs the safety switch to electrically isolate the lead from the battery cells. The battery pack also includes a manual switch, and where activation of the switch causes the controller to instruct the safety switch to electrically isolate the lead from the battery cells.

  • Patent number: 6381981
    Abstract: The present invention is directed to a container and method for shipping and storing frozen products. In particular, the present invention is directed to an insulated container for shipping and storing frozen tissue samples for an extended period of time, for example at least 72 hours. An exemplary embodiment of the container of the present invention includes a body having an open end and a product chamber lined with vacuum insulated panels, a spring assembly inside of the product chamber for supporting a lower cooling block and a stack of tissue packages (e.g. engineered tissue samples), and a lid assembly including one or more upper cooling blocks suspended therefrom. When the lid assembly is secured on the body of the container, the tissue packages are held in place between the upper and lower cooling blocks by the force of the spring assembly. The body of the container is dimensioned so that it may fit within an outer cardboard carton if desired for shipping.
