摘要： A method includes, receiving: (i) a selected three-dimensional (3D) section that has been ablated in a patient organ in accordance with a specified contour, and (ii) a dataset, which is indicative of a set of lesions formed during ablation of the selected 3D section. The selected 3D section is transformed into a two-dimensional (2D) map, and checking, on the 2D map, whether the set of lesions covers the specified contour.

摘要： A method, including receiving, from electrodes positioned within a heart, first signals from at least three of the electrodes indicating electrical activity in tissue with which the at least three of the electrodes engage, and second signals indicating locations of the at least three electrodes. The second signals are processed to compute the locations of the at least three electrodes and to determine a geometric center of the locations. Based on the signals, an electroanatomical map is generated for an area of the tissue including the geometric center, and an arrhythmia focus is determined in the map. A circle is presented, and within the circle, a region of the map is presented including the geometric center and the focus so that the geometric center on the map aligns with a center of the circle, the region within the circle indicating a spatial relationship between the geometric center and the focus.

摘要： A balloon catheter has a central tube that is configured to both structurally support and inflate a balloon membrane. The central tube has a lumen and sidewall inflation ports that provide a path for inflating the balloon. The lumen of the central tube is obstructed by a distal end piece, nose piece, or other structure to prevent fluid from exiting a distal end of the central tube. The central tube is configured such that, during inflation, inflation media is allowed to pass through an elongated shaft of the catheter, into a proximal open end of the central tube, and through the inflation ports into the balloon. The central tube can slide longitudinally in relation to the shaft to longitudinally elongate and/or truncate the balloon.

摘要： A medical system includes a probe, an electro-optical measurement unit, and a processor. The probe is configured for insertion into a blood vessel of a brain, and includes two optical fibers, which include each an optical diffuser at distal ends thereof. One fiber is configured to guide an optical signal to a location along the blood vessel and to diffuse the optical signal so as to interact with a brain clot in the blood vessel. The other fiber is configured to collect the diffused optical signal that interacted with the brain clot at another location along the blood vessel. The electro-optical measurement unit is configured to transmit the optical signal to one optical fiber, and to receive and measure the diffused optical signal from the other optical fiber. The processor is configured to identify a composition of the brain clot by analyzing the measured diffused optical signal.

摘要： Medical apparatus includes a probe with a basket assembly at its distal end, including a plurality of resilient spines with multiple electrodes arrayed along a length of each of the spines. Processing circuitry is configured to acquire a first bipolar electrical signal from the tissue between first and second electrodes at first and second locations along a first spine of the basket assembly, and to acquire a second bipolar electrical signal from the tissue between the first electrode and a third electrode in a third location on a second spine of the basket assembly, and to interpolate, based on the first and second bipolar electrical signals, a vectorial electrical property of the tissue along an axis that passes through the first location and between the second and third locations.

摘要： A catheter includes a shaft for insertion into an organ of a patient, and an expandable distal-end assembly, which is coupled to the shaft and to an apex of the catheter, and includes multiple splines. In at least a given spline among the multiple splines, at least sixty percent of a length of the given spline is non-insulated and is configured to make contact with tissue of the organ and to apply radiofrequency (RF) pulses to the tissue.
