Abstract: Magnetic field sensors and methods for 3D-printing of the same are disclosed. The magnetic field sensor includes a monolithic body with a plurality of coils 3D-printed therein by successive printing of layers along a printing direction; the coils include longitudinally oriented coil(s) whose magnetic axe(s) are parallel to the printing direction and transversely oriented coil(s) whose magnetic axe(s) are perpendicular to the printing direction. The transversely oriented coil(s) is each 3D-printed with a magnetic channel that curves between a pair of opposite flux collection facets being perpendicular to its magnetic axis, such that it includes a magnetic core section extending along the printing direction. Each of the longitudinally and transversely oriented coils is 3D-printed with respective arrangement of conductive windings including a plurality of turns 3D-printed in planes of the 3D-printed layers. The turns of transversely oriented coil surround the magnetic core section to the magnetic channel thereof.

Abstract: Classification of heartbeats based on intracardiac and body surface electrocardiogram (ECG) signals are provided. Intracardiac ECG (IC-ECG) signals and body surface ECG (BS-ECG) signals are processed to perform heartbeat classifications. A BS annotation of BS-ECG signals reflective of a sensed heartbeat is defined, the BS annotation including a BS annotation time value. IC annotations of IC-ECG signals which reflect atrial-activity or ventricular activity of the sensed heartbeat are also defined, each IC annotation including an IC annotation time value. The IC-ECG signals are discriminated as A-activity or V-activity and IC annotations are designated as IC-A annotations or IC-V annotations, respectively. A respective A/V time sequence comparison of IC annotations reflective of the sensed heartbeat is made with one or more time sequence templates for heartbeat classification. Morphology comparisons of the BS-ECG oscillating signal segments reflective of the sensed heartbeat morphology templates for classification may also be made.

Abstract: Catheterization of the heart is carried out using a framework formed by a plurality of electrically conducting wire loops. The wire loops are modeled as polygons, each subdivided into a plurality of triangles. The wire loops are exposed to magnetic fluxes at respective frequencies, and signals read from the loops. Theoretical magnetic fluxes in the polygons are computed as sums of theoretical magnetic fluxes in the triangles thereof. The location and orientation of the framework in the heart is determined by relating the computed theoretical magnetic fluxes to the signals.

Abstract: A system includes secondary and primary catheters, and a processor. The primary catheter includes shaft for insertion into an organ of a patient, first position sensor disposed on a distal end of the shaft, expandable assembly coupled at the distal end of the shaft, the assembly comprising hollow channel to allow passage of the secondary catheter distally via the assembly, and plurality of second position sensors disposed along a distal end of the secondary catheter, which are configured to indicate a respective plurality of positions along its distal end. The processor is configured to receive the indications of the positions, apply a model of known mechanical properties of the distal end of the secondary catheter to the positions to compute bending profile of the secondary catheter inside the assembly, and based on the computed bending profile, estimate orientation of the assembly relative to the distal end of the shaft.

Abstract: An irrigated ablation catheter adapted for direct tissue contact has micro-elements that provide more accurate sensing of tissue, including thermal and electrical properties for temperature and impedance measurements. The micro-elements extend through a hollow chamber of an irrigated ablation electrode, and distal ends thereof can protrude outside of electrode or be flush with the electrode. The micro-elements have a protective guide tube in which components enabling temperature sensing or electrical sensing are encased.

Abstract: A method, consisting of modeling physical parameters representative of a probe in proximity to body tissue during an ablation procedure performed by the probe. The method also includes measuring a subgroup of the physical parameters during a non-ablation stage of the ablation procedure so as to generate measured non-ablative values of the subgroup, and measuring the subgroup of the physical parameters during an ablation stage of the ablation procedure so as to generate measured ablative values of the subgroup. In response to the modeling, the method includes generating calculated non-ablative values of the subgroup for the non-ablation stage, and generating calculated ablative values of the subgroup for the ablation stage. The method compares the measured non-ablative values with the calculated non-ablative values, and compares the measured ablative values with the calculated ablative values, so as generate optimal values of the physical parameters.

Abstract: A method includes, in a processor, receiving example representations of geometrical shapes of a given type of organ. In a training phase, a neural network model is trained using the example representations. In a modeling phase, the trained neural network model is applied to a set of location measurements acquired in an organ of the given type, to produce a three-dimensional model of the organ.

Abstract: Systems and methods for optimal selection of beats for a 3D mapping are disclosed. A method in accordance with the present disclosure may be performed on a processor and may comprise receiving a plurality of beats from a catheter. The catheter may be located at a target mapping site, such as a chamber of the heart. A plurality of dynamic filters may be applied to the plurality of collected beats. The optimal beats may be determined and integrated as a beat in the 3D mapping system. This method enables the selection of more beats for a more comprehensive 3D mapping, as well as the selection of more quality beats that are representative of the target anatomy.
