  • Publication number: 20200289199
    Abstract: An electrosurgical instrument for applying microwave energy to biological tissue, where the instrument is capable of freezing biological tissue in a region around a radiating tip portion and applying microwave energy to the frozen tissue. By freezing the region around the radiating tip portion, microwave energy radiated from the radiating tip portion can be transmitted through the frozen region with low losses and into tissue surrounding the frozen region. This enables the size of the treatment area to be increased without having to increase the amount of microwave energy delivered to the radiating tip portion. The instrument comprises a transmission line, a radiating tip, a fluid feed for conveying a tissue-freezing fluid, and a thermal transfer portion arranged to provide thermal communication between the tissue-freezing fluid and biological tissue in a treatment zone.

  • Publication number: 20200289198
    Abstract: An electrosurgical apparatus for tightening ligaments using microwave energy. A detector is used to obtain information about a treatment zone. Based on this information, an energy delivery profile is determined. The energy delivery profile is selected to cause desired thermal effects in target tissue (e.g. ligaments, tendons or the like) without unwanted thermal side effects is determined and delivered. With this apparatus, energy can be delivered in a precise manner to the target tissue. The energy delivery profile may be based on a complex impedance, or attenuation and/or phase constants of the type of body tissue in the treatment zone.

  • Publication number: 20200289195
    Abstract: An electrosurgical instrument which is capable of simultaneously ablating an area of tissue with microwave energy and performing resection with RF energy. The instrument comprises a structure for conveying both RF and microwave energy to an instrument tip that is configured to emit the microwave energy in a manner suitable for ablation (e.g. as a substantially spherical field) and to emit the RF energy in a more focussed manner to enable accurate and controllable resection to be performed. The energy conveying structure comprises a coaxial transmission line for conveying microwave energy. The coaxial transmission line has a hollow inner conductor that defines a passage that supports a second transmission line for conveying radiofrequency energy.

  • Publication number: 20200222112
    Abstract: An electrosurgical resector tool having an energy delivery structure that provides a plurality of operational modalities that facilitate biological tissue cutting and sealing using radiofrequency (RF) electromagnetic (EM) energy and/or microwave EM energy. The tool comprises a static first blade element, and a pivotable second blade element that has a length commensurate with the first blade element whereby, in a closed position, it lies adjacent to a laterally facing surface of the first blade element. The blade elements constitute an energy delivery mechanisms that is compact enough to enable the tool to be insertable through an instrument channel of a surgical scoping device, such as an endoscope, gastroscope or bronchoscope.

  • Publication number: 20200018531
    Abstract: Systems and methods for a vapor compression system including primary actuators, secondary actuators, primary sensors that provide a primary set of system outputs, and secondary sensors that provide a secondary set of system outputs. A primary controller receives the primary set of system outputs, and produces a primary set of control inputs for the primary actuators, to regulate one or more zone temperatures to set-points and to regulate one or more critical process variables to set-points. A secondary controller receives the secondary set of system outputs, and produces a secondary set of control inputs, to minimize an overall system power consumption. The secondary inputs may include set-points to the primary controller. The primary outputs may include estimates of critical process variables that are used as inputs to the secondary controller.
