Publication number: 20200261263Abstract: Cold plates through which refrigerant flows define a slot between them that can receive a cassette through which sterile working fluid with a relatively low flow rate flows from an intravascular heat exchange catheter or external pad. The slot may have bulge cavities along the edges to permit the membrane of the cassette to expand and thus establish fluid supply and return passageways.Type: ApplicationFiled: December 17, 2019Publication date: August 20, 2020Inventors: Jeremy Thomas Dabrowiak, Craig Wendell Pendry, Christoph Matthias Pistor

Patent number: 9687986Abstract: Methods and apparatus for manufacturing and controlling an elongate robotic instrument, or robotic endoscope, are provided which may include any number of features. One feature is a robotic link that can be easily manufactured and can withstand the forces related to use within a robotic instrument. Another feature is a joint on the link that increases compressive strength and minimizes stress between links. Yet another feature is an elongate robotic instrument that is constructed from a single type of link.Type: GrantFiled: November 10, 2009Date of Patent: June 27, 2017Assignee: Intuitive Surgical Operations, Inc.Inventors: Christoph Matthias Pistor, Joshua T.
