  • Publication number: 20200325430
    Abstract: A system and method for printing cells in a medium. A multi-dimensional printer, stably constructed of low-mass parts, can include a computer numerically controlled system that can enable motors driving delivery systems. The motors can include encoders that can enable achieving arbitrary resolution. The motors can drive ballscrews to enable linear motion of delivery systems, and the delivery systems can enable printing of a biological material in a pre-selected pattern in a petri dish. The petri dish can accommodate a medium such as a gel, and can further accommodate a vision system that can detect actual position and deflection of the delivery system needle. The printer can accommodate multiple delivery systems and therefore multiple needles of various sizes.

  • Publication number: 20190316948
    Abstract: A system including a pumping cassette having a first side including number of valve wells and second side having a fluid bus. Each side may be covered by a flexible membrane. A control surface having a number of valve well control stations actuatable with respect to the flexible membrane covering the first side of the cassette to open and close the valve wells when the cassette is mated against the control surface may be included. A pressure distribution assembly having a positive and negative pressure source and a number of pneumatic valves may be included. A controller configured to selectively actuate the number of pneumatic valves to apply pressure against the valve well control stations in a valve pumping sequence until a volume displaced through the fluid bus of the pumping cassette from a source to a destination is within a range of a target volume may be included.

  • Publication number: 20190039241
    Abstract: A force transmission system as part of a surgical system which may be configured to be a minimally invasive and/or computer assisted surgical system. Operation of the system may be controlled by transmission of a force from a first section to a second section of the system. The first section and the second section may be separated by a partition or a barrier. The first section may be a non-sterile section and the second section may be a sterile section of the surgical system.
