  • Patent number: 10792089
    Abstract: A medical device system may be configured to detect an improper energy transmission configuration therein. The condition may be detected by way of a detection of a condition where an energy-transmitting electrode of the medical device system becomes too close to or becomes in contact with an object resulting in an inability of the electrode to properly transmit energy. For example, if the energy-transmitting electrode is a first electrode configured in its operational state to transmit energy to bodily tissue adjacent the first electrode, but the first electrode is inadvertently contacting a second electrode, such contact may cause at least some energy transmitted by the first electrode to follow an unintended path away from its intended path to the adjacent tissue. Such a condition may be detected based at least upon an analysis of information acquired from a sensing device system.

The electrical wire assemblies pass through respective pockets/chambers formed within the handle, an electrical connector contained within each chamber for connecting wires extending from electrodes on the end-effector to wires extending through the handle and on connecting to an electrosurgical generator. The pockets provision within which connectors are contained, one per pocket, prevents insulation damage to wires by connectors, as they are contained within the pockets. The pockets provision pockets side-by-side provides large separation between two connectors, so it is hard for liquid to short the connectors.

  • Patent number: 10722288
    Abstract: Methods and system are provided for thermally-induced renal neuromodulation. Thermally-induced renal neuromodulation may be achieved via direct and/or via indirect application of thermal energy to heat or cool neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers. In some embodiments, parameters of the neural fibers, of non-target tissue, or of the thermal energy delivery element, may be monitored via one or more sensors for controlling the thermally-induced neuromodulation. In some embodiments, protective elements may be provided to reduce a degree of thermal damage induced in the non-target tissues. In some embodiments, thermally-induced renal neuromodulation is achieved via delivery of a pulsed thermal therapy.

  • Patent number: 10722286
    Abstract: High-voltage pulses ablation systems and methods are used to ablate tissue and form lesions. A variety of different electrophysiology devices, such as catheters, surgical probes, and clamps, may be used to position one or more electrodes at a target location. Electrodes can be connected to power supply lines and, in some instances, the power to the electrodes can be controlled on an electrode-by-electrode basis. High-voltage pulse sequences provide a total amount of heating that is typically less than that which is observed with thermally-based radiofrequency energy ablation protocols.

  • Patent number: 10682520
    Abstract: Devices, systems, and techniques for controlling charging power based on a cumulative thermal dose to a patient are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. An external charging device may calculate an estimated cumulative thermal dose delivered to the patient during charging over a predetermined period of time. Based on the estimated cumulative thermal dose, the external charging device may select a power level for subsequent charging of the rechargeable power source. In one example, the charging device may select a high power level when the cumulative thermal dose has not exceeded a thermal dose threshold and select a low power level when the cumulative thermal dose has exceeded the thermal dose threshold.

  • Patent number: 10617463
    Abstract: The electrosurgical systems and corresponding methods of the present disclosure involve an electrosurgical generator, sensing circuitry, and a controller. The electrosurgical generator includes a radio frequency (RF) output stage that supplies power to tissue. The sensing circuitry measures impedance of tissue. The controller controls the power supplied from the RF output stage to track a nonlinear power curve until the power supplied from the RF output stage has reached a predetermined peak power of the nonlinear power curve. The controller further determines whether a tissue reaction has occurred based on impedance measured by the sensing circuitry and controls the power supplied from the RF output stage during a cooling phase if the controller determines that a tissue reaction has occurred. The controller may further control the power supplied from the RF output stage to track a linear power curve.
