摘要： Methods and systems provide for coordinating multiple different types of ablation modes, such as Radio Frequency (RF) ablations of tissue portions with Pulsed Field ablations (PFA), for ablating tissue portions, e.g., ablation sites in the tissue, during a procedure, such as an ablation procedure on a cardiac wall.

摘要： A system includes a display and a processor a display and a processor. The display is configured to display multiple pixels of an image of an organ having a cavity and tissue surrounding the cavity. The processor is configured to: (1) receive an ultrasound (US) signal of at least the cavity and the tissue and one or more position signals in the organ indicative of one or more positions of one or more catheters having a known geometry, respectively, and (2) based on the one or more position signals, the known geometry, and the US signal: (i) identify in the image a given pixel at a given position, and (ii) display the given pixel as: (a) a first pixel indicative of the cavity responsively to identifying that the given position corresponds to the one or more positions, or (b) a second pixel indicative of the tissue.

摘要： A method includes, in a processor, receiving signals from (i) a first position sensor disposed on a shaft of a catheter, and (ii) a second position sensor disposed on a distal end of a sheath of the catheter. Based on the signals received from the first position sensor and the second position sensor, an event is detected in which an expandable distal-end assembly of the catheter is being withdrawn into the sheath while still at least partially expanded. A responsive action is initiated in response to detecting the event.

摘要： A system includes a display and a processor. The processor is configured to (a) receive multiple signals sensed by multiple electrodes of a multi-electrode catheter in a heart of a patient, (b) determine which of the electrodes are to be active in an ablation procedure, and (c) present the multiple signals to a user, on the display, using a graphical user interface (GUI) that (i) visualizes the signals from the electrodes determined to be active by a first graphical feature, and (ii) visualizes the signals from the electrodes determined not to be active by a second graphical feature, different from the first graphical feature.
