摘要： A catheter includes, a shaft for insertion into an organ, an expandable distal-end assembly coupled to the shaft and includes splines, at least one of the splines includes a flexible substrate, configured to conform to tissue of the organ, and a sensing electrode, configured: (a) to be coupled to the flexible substrate, and (b) when in contact with the tissue, to produce a electrically signal indicative of an electrocardiogram signal sensed in the tissue, the sensing electrode including: (i) a gold substrate, formed over the flexible substrate and configured to conduct the electrically signal, (ii) a first polymer layer, formed over a first section of the gold substrate and configured to electrically isolate between the tissue and the gold substrate, and (iii) a second polymer layer, formed over a second, different, section of the gold substrate, and configured to conduct the electrocardiogram signal between the tissue and the gold substrate.

摘要： A system for use with multiple electrodes coupled to respective spines of a probe includes multiple switches connected to the electrodes and configured to short different respective first subsets of the electrodes to each other and different respective second subsets of the electrodes to each other per different respective settings of the switches. The system further includes a processor configured to control the switches so as to alternate through the settings and, for each of the settings, cause a power generator to apply a voltage between the shorted first subset and the shorted second subset while the probe is deployed within a body of a subject. Other examples are also described.

摘要： A method includes emitting an ultrasound beam from an array of ultrasound transducers in a catheter placed in a blood pool in an organ. Echo signals reflected in response to the ultrasound beam are received in the array. Distinction is made in the echo signals between (i) first spectral signal components having Doppler shifts characteristic of blood and (ii) second spectral signal components having Doppler shifts characteristic of tissue of the organ. The first spectral signal components are suppressed relative to the second spectral signal components in the echo signals. An ultrasound image of at least a portion of the organ is reconstructed from the echo signals having the suppressed first spectral signal components. The reconstructed image is displayed to a user.

摘要： In one embodiment, a medical system includes a catheter configured to be inserted into a chamber of a heart of a living subject, and including catheter electrodes configured to contact tissue at respective locations within the chamber of the heart, a display, and a processing circuitry configured to receive respective signals from the catheter captured by respective ones of the electrodes, assess conformity of each of the respective signals to at least one signal characteristic, find a given one of the signals of a given one of the electrodes not conforming to the at least one signal characteristic for a given time period, and render to the display an indication that the given signal of the given electrode does not conform to the at least one signal characteristic for the given time period.

摘要： In one embodiment, a medical system includes a catheter configured to be inserted into a chamber of a heart of a living subject, and including a distal end including catheter electrodes configured to contact tissue at respective locations within the chamber of the heart, at least one position sensor configured to provide at least one position signal indicative of a position of the distal end, a display, and processing circuitry configured to compute the position of the distal end of the catheter responsively to the at least one position signal, render to the display a 3D anatomical map of the chamber of the heart and a 3D representation of the distal end of the catheter, and render to the display over at least part of the map, at least one intracardiac electrogram trace representing electrical activity in the tissue that is sensed by at least one of the catheter electrodes.

摘要： A system includes an interface and a processor. The interface is configured to receive an electrogram acquired in a heart of a patient. The processor is configured to (i) estimate a level of injury current present in the electrogram, and (ii) based on the estimated level of injury current, decide whether to use the electrogram in a subsequent analysis.

摘要： A method includes emitting an ultrasound beam, having a predefined field of view (FOV), from an array of ultrasound transducers in a catheter in an organ of a patient. Echo signals are received in the array, in response to the ultrasound beam. A position of a target object is estimated within the FOV. When the estimated position of the target object violates a centering condition, the FOV of the ultrasound beam is automatically modified to re-meet the centering condition.

摘要： A method includes generating an ablation programming language, which defines commands for (i) setting ablation protocol parameters and respective values, (ii) setting a configuration of an ablation system, (iii) applying automatic logic that relates the ablation protocol parameters and the values to the configuration of the ablation system, and (iv) generating one or more graphical user interfaces (GUIs) showing one or more of the parameters of the ablation protocol and the system configuration. The ablation programming language is provided for subsequent use with the ablation system.

摘要： A catheter includes a shaft for insertion into an organ of a patient, an expandable distal-end assembly, and at least an electrical interconnection. The expandable distal-end assembly is coupled to the shaft and includes multiple splines, at least one of the splines includes a flexible substrate, which is configured to conform to tissue of the organ. The electrical interconnection has: (i) a first section, which is formed within the flexible substrate and is configured to conduct ablation signals, and (ii) a second section thicker than the first section, which is formed over an outer surface of the flexible substrate and is configured to apply the ablation signals to the tissue.
