摘要： A method, including ejecting irrigation fluid from a distal end of a probe so as to irrigate tissue, and receiving, over a period of time, initial signals indicative of respective temperatures of the distal end, from a temperature sensor in the distal end. The method also includes formulating from the initial signals a temperature range between upper and lower temperature thresholds and, when a further signal from the temperature sensor, received subsequent to the period of time, is indicative of a further temperature above the upper temperature threshold, raising an alarm that a bubble is present in the irrigation fluid.

摘要： A system for use with a catheter having a distal structure including a plurality of electrodes includes a display and a processor. The processor is configured to ascertain a number of the electrodes contacting an ostium of a pulmonary vein, and in response to the number equaling or exceeding a predefined lower threshold, carry out an iterative process. The process includes, during each iteration of the process, in response to the number being less than a predefined higher threshold, computing an adjustment to a current pose of the distal structure, and displaying, on the display, a target-pose icon, which represents the distal structure, offset, per the adjustment, from a current-pose icon representing the distal structure at the current pose. Other examples are also described.

摘要： A system for use with a balloon disposed at a distal end of an intrabody probe includes an output device, configured to produce an output indicating whether the balloon is elongated, and a processor. The processor is configured to calculate, based on respective locations of multiple elements disposed on a surface of the balloon, multiple values, over an interval, of a parameter indicative of a radius of the balloon. The processor is further configured to modify a state of the output based on at least one of the values. Other embodiments are also described.

摘要： Described embodiments include a system that includes a current source generator and a processor. The processor is configured to drive the current source generator to supply, for application to tissue of a subject, an electric current having an amplitude that varies in accordance with a predefined function of time, such that the amplitude initially monotonically increases to a maximum value. Other embodiments are also described.
