  • Patent number: 11981030
    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.

  • Publication number: 20240066217
    Abstract: A care assembly placement system may comprise an inserter including a port with a coupling interface and a receptacle body including tracks partially swept around the axis of the port. The system may further comprise a cartridge including a retainer with a care assembly coupled thereto and a sharp holder having a first end bearing a sharp. The retainer may include projections. The sharp holder may include a coupling interface opposite the first end. When the cartridge is placed in an aligned position relative the receptacle body and rotated to a coupled state, the projections may each displace along a ramp of a respective track in a first displacement range translationally driving the cartridge to a position in which sharp holder and port coupling interfaces are aligned. The sharp holder coupling interface may be rotated into engagement with the port coupling interface in a second displacement range of the cartridge.

  • Publication number: 20230105287
    Abstract: A system and method to enable treatment through cell therapy. The system can enable cell injection such as, for example, injecting beta cells/islets, cartilage cells, fat cells, and others. The system and method ensure that the delivery rate and delivered volume of the material pumped through a tube and into the injection needle is consistent over the course of the start-operation-stop process from run to run. The system and method can automatically stop delivery and alarm if an occlusion is detected during delivery.

  • Publication number: 20220169963
    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.
