  • Patent number: 10729485
    Abstract: Body tissue ablation is carried out by inserting a probe into a body of a living subject, urging the probe into contact with a tissue in the body, generating energy at a power output level, and transmitting the generated energy into the tissue via the probe. While transmitting the generated energy the ablation is further carried out by determining a measured temperature of the tissue and a measured power level of the transmitted energy, and controlling the power output level responsively to a function of the measured temperature and the measured power level. Related apparatus for carrying out the ablation is also described.

  • Patent number: 10722139
    Abstract: A method, including advancing a guidewire having a first diameter through a patient lumen, the guidewire being tracked by an electromagnetic system and an impedance system. While advancing the guidewire, signals of both systems, that are generated in response to differing positions of the guidewire in the lumen, are recorded. The method includes recording correspondences between the signals at each of the differing positions. The method also includes withdrawing the guidewire from the lumen, and then advancing through the lumen a second guidewire, having a second diameter smaller than the first diameter, which is tracked by the impedance system. While advancing the second guidewire, a signal of the impedance system generated in response to advancement of the second guidewire in the lumen is received. The method includes applying the correspondences to the signal in order to determine a position of the second guidewire in the lumen.

  • Publication number: 20200225294
    Abstract: A cable, an associated monitoring system and methods are provided which monitor the continuity of current of electrical components such as sensor signals from sensors used in connection with a medical apparatus. The cable includes a proximal end for coupling with a processing unit and a distal end with or for coupling to sensors. The processing unit generates a continuity signal that travels through the cable via an inductor coil conductor to a distal end inductor coil which imparts the signal to sensor signal conductors of the cable. The continuity signal is carried back to the processing unit with signals from the sensors. Circuitry of the processing unit can detect the returning continuity signals to indicate proper connectivity of the sensor signals. The connection status information of the sensors can be displayed to inform a doctor or other operator of the medical apparatus of sensor signal continuity.
