摘要： Apparatus, including a tube having a proximal end, and a distal end for insertion into a body cavity including anatomical structures, and a blade mounted at the distal end. The apparatus also includes a handle at the proximal end and including a device which generates sensible outputs upon receiving activation signals, and a position sensor fixed in a predefined disposition relative to the tube. The apparatus additionally includes a processor configured to acquire an image of the cavity, to determine, in the image, locations for each of the structures, to receive, from the sensor, a position signal indicative of a blade location of the blade within the cavity, to determine, based on the blade location and the respective structure locations, a proximity of the blade to a given structure, and to convey, to the warning device, a given activation signal in response to the proximity to the given structure.

摘要： Cardiac catheterization is carried out by memorizing a designation of a contact state between an electrode of the probe and the heart wall as one of an in-contact state and an out-of-contact state, and making a series of determinations of an impedance phase angle of an electrical current passing through the electrode and another electrode, identifying maximum and minimum phase angles in the series, and defining a binary classifier adaptively as midway between the extremes. A test value is compared to the classifier as adjusted by a hysteresis factor, and a change in the contact state is reported when the test value exceeds or falls below the adjusted classifier.

摘要： A method for operating a medical probe includes pressing a distal end of the medical probe, which includes one or more arms that extend diagonally outward from a central shaft and have respective position transducers coupled thereto, against an intra-body surface, so as to cause the arms to exert pressure on the surface and bend with respect to the central shaft in response to the pressure. Positions of the respective position transducers coupled to the arms are measured, and the pressure exerted by the arms is estimated responsively to the measured positions.

摘要： Testing a thermocouple-based RF ablation system is carried out by connecting a temperature simulator to an ablator module. The ablator module is operative to vary a radiofrequency power output thereof in a predefined manner in response to predefined variations in a temperature signal from the simulator. The method is further carried out by delivering RF power from the ablator module to the temperature simulator, and while delivering RF power, performing the steps of: communicating temperature signals from the temperature simulator to the ablator module, varying the communicated temperature signals, and verifying that a variation in the power output of the ablator module in response to varying the temperature signals conforms to the predefined manner.
