摘要： A method for medical diagnosis, consisting of receiving electrophysiological data including first intracardiac electrogram (IEGM) signals acquired by a first pair of electrodes having a first intracardiac electrode. The data includes second IEGM signals acquired by a second pair of electrodes having a second intracardiac electrode in proximity to the first intracardiac electrode. The first and second IEGM signals are input to a first convolutional layer of a neural network and a second convolutional layer parallel to the first convolutional layer in the neural network to generate respective first and second interim results. The first and second interim results are input into one or more common layers of the neural network. The method includes receiving from an output layer of the neural network, responsively to inputting the first and second interim results, an indication of a local activation time at a location of the first and second intracardiac electrodes.

摘要： A medical apparatus includes a registration tool, which includes a position sensor, A position-tracking system is configured to acquire position coordinates of the sensor in a first frame of reference defined by the position-tracking system. A processing unit is configured to receive 3D image data with respect to the body of the patient in a second frame of reference, to generate a 2D image of the surface of the patient based on the 3D image data, to render the 2D image to a display screen, and to superimpose onto the 2D image icons indicating locations of respective landmarks. The processing unit receives the position coordinates acquired by the position-tracking system while the registration tool contacts the locations on the patient corresponding to the icons on the display, and registers the first and second frames of reference by comparing the position coordinates to the three-dimensional image data.

摘要： A medical apparatus includes a probe configured for insertion into a body of a patient. The probe includes electrodes configured to contact tissue of a region within the body. The apparatus further includes a display screen, a position-tracking system configured to acquire position coordinates of the electrodes within the body, and a processor. The processor is configured to acquire electrophysiological signals from the electrodes while they are held stationary in the region, extract electrophysiological parameters from the signals, compute a measure of consistency of the parameters, and render to the display screen a three-dimensional (3D) map of the tissue while superimposing on the map, responsively to the position coordinates, a visual indication of the extracted parameters at the locations for which the measure of consistency satisfied a consistency criterion, and automatically discarding from the map the parameters for which the measure of consistency did not satisfy the consistency criterion.

摘要： An apparatus includes a shaft assembly and a distal endoscope cap. A flexible distal portion of the shaft assembly is laterally deflectable relative to a rigid proximal portion of the shaft assembly. The shaft assembly defines a working channel sized and configured to enable advancement of a working element. The distal endoscope cap is configured to attach to the distal end of the shaft assembly. The distal endoscope cap has an outer diameter that is larger than the outer diameter of the flexible distal portion. The distal endoscope cap includes a body having at least one coupling member for attaching the distal endoscope cap to the distal end of the shaft assembly, at least one image sensor secured to the body for visualizing an anatomical structure, and at least one illuminating element secured to the body for illuminating a field of view of the at least one image sensor.
