  • Patent number: 10265124
    Abstract: A catheter carries a position sensor in a distal, on-axis position in an irrigated ablation tip electrode. The tip electrode has a shell wall that defines a cavity through which fluid flows and exits via fluid ports formed in the shell wall. The cavity is sealed by an internal member extends into the cavity with a baffle portion and a distal portion. The distal portion safely houses the position sensor and the baffle portion diffuses and disperses fluid entering the tip electrode for a more uniform flow through the cavity. The distal portion is configured to provide an annular region that runs along the length of the tip electrode to better feed fluid to the more distal fluid ports on the tip electrode for more uniform cooling at all locations on the tip electrode.

  • Patent number: 10231773
    Abstract: System and method for selectively applying electrical energy to structures within or on the surface of a patient's body and controlling the flow of an electrically conductive fluid from the application site to provide or maintain a desired operating condition of the electrosurgical device. An electrosurgical probe is in communication with a fluid transport apparatus through a fluid transport lumen having an opening at an end proximate the application site and disposed proximate the electrosurgical probe. A controller in communication with the fluid transport apparatus provides control signals to the fluid transport apparatus in response to at least one operating parameter associated with the system. Based on the received control signals, the fluid transport apparatus adjusts a flow rate of the electrically conductive fluid at the application site through the fluid transport lumen in response to at least one operating parameter associated with the system.

  • Patent number: 10231775
    Abstract: A robotic surgical system is provided that includes an electromechanical tool coupled to a surgical instrument such as an end effector adapted to apply ultrasound energy to tissue when the end effector holds the tissue. The electromechanical tool is mounted on an electromechanical arm and configured to move relative to the arm. A controller operatively coupled to the tool and the arm measures electrical impedance of tissue as ultrasound energy is applied to the tissue by the end effector. The controller determines, based on the tissue impedance measurements, that the tissue is fully cauterized. In response to the detection, the surgical system automatically lifts the end effector, either by lifting the arm to which it is coupled or independently from that arm, thereby the end effector cuts the cauterized tissue to complete the tissue cauterization/cutting. The controller also determines and controls a velocity with which the end effector is lifted.
