    摘要： Apparatuses and methods for imposing electric fields through a target region a patient are described. An apparatus includes a transducer array having a first and second electrode element receiving an alternating current waveform and a sensor array having a first temperature sensor positioned to detect a first temperature of the first electrode element and a second temperature sensor positioned to detect a second temperature of the second electrode element. The first temperature sensor is connected to a first conductor and second conductor. The second temperature sensor is connected to the second conductor and third conductor. A circuit provides a first known amount of electricity via the first conductor and second conductor to obtain the first temperature and a second known amount of electricity via the second conductor and the third conductor to obtain the second temperature. A controller adjusts the alternating current waveform based on the temperatures.

    摘要： Apparatus and methods for imposing electric fields through a target region in a body of a patient are described. The apparatus includes a sensor array having a plurality of temperature sensors with a plurality of first temperature sensors of the sensor array connected to a first conductor, and a plurality of second temperature sensors connected to a second conductor. A circuit is configured to provide a known amount of electricity via the first conductor and the second conductor to a third temperature sensor, the third temperature sensor within the plurality of first temperature sensors, and within the plurality of second temperature sensors.

    摘要： A tissue resecting or other medical device includes a handle coupled to an elongated shaft. A radiofrequency (RF) electrode is carried at a distal end of the elongated shaft, and the electrode is moveable across a window in a sleeve or other component of the shaft. The shaft has an interior channel connectable to a negative pressure source to remove debris from the channel. A motor is carried by the handle and operatively coupled to the electrode for moving the electrode relative to the window. An electronic image sensor and lens are disposed at a distal end of the shaft, and a plurality of conductors may extend through the shaft to the image sensor. The image sensor, lens and sensor conductors are disposed within a first tubular member, and an LED or other light source is also positioned at a distal end of the shaft with LED conductors or leads extending through a second tubular member of the shaft to the LED.
