摘要： Methods, devices, and systems related to electrosurgical tools are provided. The electrosurgical tools can include an electrode formed of non-linear resistance material for allowing energy to be transmitted to the electrode for heating the electrode or to tissue adjacent the electrode for heating the tissue. Such transmission of the energy can depend upon a characteristic of the electrical energy, such as voltage or frequency of the energy, which can affect the resistance properties of the electrode.

摘要： An irrigated electrophysiology catheter has a tip electrode having a shell, and a support member configured to plug the shell and support one or more tip components and/or facilitate their functions. Advantageously, the support member has an electrically-conductive interface portion and an insert-molded portion, wherein the interface portion, typically constructed of a precious metal alloy, is structurally minimized, yet still configured for electrical connection with the shell and the lead wire, so as to reduce the amount and hence the cost of its manufacture, whereas the insert-molded portion is constructed of a significantly less-costly material and is readily configured with micro-complex 3-D geometry adapted to support tip structure and functions including irrigation, force sensing and temperature sensing, as a further cost savings in the manufacturing of the tip electrode by reducing materials, labor and time.

摘要： A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.

摘要： A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector disposed at a distal end of the shaft, an actuator operably coupled to the housing, an actuation assembly, and a sensor module. The actuation assembly extends through the housing and the shaft and includes a distal end operably coupled to the end effector or a component associated therewith, a proximal end operably coupled to the actuator, and a spring. Actuation of the actuator manipulates the end effector or deploys the component relative thereto. The sensor module is disposed within the housing and configured to sense a property of the spring indicative of an amount the spring has been compressed. The sensor module is further configured, based upon the sensed property, to determine a condition of the end effector or the relative position of the component.

摘要： A renal denervation system includes an ablation catheter and an inflation balloon. The renal denervation catheter is insertable into a renal artery to perform a renal denervation procedure. The inflation balloon is inflatable within the renal artery, wherein one of a blood pressure condition in the renal artery resulting from operation of the inflation balloon and a performance characteristic of the inflation balloon indicates efficacy of the renal denervation procedure.

摘要： A catheter probe comprises an insertion tube, and a distal end with a distal electrode, a force sensor to detect force on the distal electrode, and an irrigated electrode mounted on a coupling member of the force sensor, which has a tubular form surrounding a central space occupied by components, including force sensing coils. A fluid diverter that passes fluid to the proximal irrigated electrode is configured as an insert or an integrated projection of the coupling member, which configuration minimizes its space demand within the coupling member. Thus, the diameter of the distal end need not be increased. The fluid diverter has a proximal entry opening and a distal exit opening connected by a fluid passage with at least a radial branch and at least an axial branch. The irrigated electrode is mounted over the distal exit opening to receive fluid from the fluid passage.
