摘要： An end effector having loop members with electrodes thereon and are usable with catheter-based systems to measure or provide electrical signals. The end effector can include three loop members that are non-coplanar when expanded unconstrained that become contiguous to a planar surface when the loop members are deflected against the surface, a mechanical linkage that joins the loop members at a distal vertex of the end effector. The end effector may have a lateral gap length between laterally adjacent electrodes approximately twice that of a longitudinal gap length between longitudinally adjacent electrodes. In some configurations, longitudinal electrode bipole pairs having a gap distance approximately equal to the lateral gap distance may be provided by bypassing every other electrode in the longitudinal direction.

摘要： An apparatus includes a catheter and an end effector. At least a portion of the catheter is sized and configured to fit within a lumen of a human cardiovascular system. The end effector is positioned at a distal end of the catheter. The end effector includes an expandable assembly and at least one flex circuit. The expandable assembly is configured to transition between a non-expanded state and an expanded state. The expandable assembly includes at least one deformable strut or cage. Each flex circuit includes a flexible substrate secured, without an adhesive, to the expandable assembly and an electrode secured to the flexible substrate. The expandable assembly in the expanded state is configured to urge the electrode into contact with tissue. The electrode has a fishbone-like configuration that defines a longitudinally elongated portion and a plurality of fingers extending transversely from the longitudinally elongated portion.

摘要： An apparatus includes an interface and a processor. The interface is configured to receive one or more magnetic-positioning signals from one or more position sensors coupled to one or more body-surface patches attached to a body of a patient, the magnetic-positioning signals indicative of respective positions of the position sensors. The processor is configured to (i) detect an inadvertent stimulation of a phrenic nerve of the patient, which occurs due to cardiac pacing applied by an intra-cardiac electrode in a heart of the patient, (ii) estimate, based on the magnetic-positioning signals, a motion of one or more of the body-surface patches occurring during the detected stimulation of the phrenic nerve, (iii) estimate, based on the estimated motion of the body-surface patches, a distance between the pacing electrode and the phrenic nerve, and (iv) send an output derived from the estimated distance to the output device.

摘要： A method includes, receiving a first electrocardiogram (ECG) signal, which is acquired in a heart of a patient and is distorted by interference. One or more external signals that sense the interference concurrently with acquisition of the first ECG signal are received from one or more sources external to the heart. A second ECG signal, in which the interference is suppressed relative to the first ECG signal, is produced by applying a trained Neural Network (NN) to the first ECG signal and to the one or more external signals.
