  • Patent number: 12104994
    Abstract: At least some embodiments of the technology are directed to an automated slide processing apparatus configured to apply at least one reagent to a specimen carried by a microscope slide. The slide processing station can include a support element with a support surface, at least one vacuum port, and a sealing member having a non-round shape. In an uncompressed state, the scaling member can extend upwardly beyond the support surface. In a compressed state, the scaling member can be configured to maintain an airtight seal with a backside of the microscope slide as the microscope slide is pulled against the support surface by a vacuum drawn via the at least one vacuum port.

  • Patent number: 8152820
    Abstract: A coaxial tube assembly, a bag, a bag-translating assembly, a de-bulking tool, and a drive assembly. The bag is delivered into a cavity in a patient's body either manually for open surgery or through the coaxial tube assembly by operation of the drive assembly for minimally invasive surgery. After a mass of tissue is placed in the bag, which is now secured to the bag-translating assembly, the drive assembly is operated to activate the bag-translation assembly to retract the bag into the annular space of the coaxial tube assembly. As the bag is being retracted, the mass in the bag is pulled into engagement with the de-bulking tool, which extends through the lumen of the coaxial tube assembly. The drive assembly activates the de-bulking tool to morcellate the mass in the bag and convey the morcellated bits of the mass through the lumen of the coaxial tube assembly.
