Abstract: Magnetic position sensors include features to enhance performance and durability. In many embodiments, a magnetic position sensor includes a magnetically permeable core and a coil. The core has a central axis and a core length along the central axis. The coil is configured to generate output an electric signal in response to a magnetic field. The coil has a coil length along the central axis that is less than the core length. In some embodiments, a magnetic position sensor includes a magnetically permeable core, a coil, a pair of signal wires, and a third wire. The coil is configured to output an electric signal in response to a magnetic field. The pair of signal wires is connected to and extends from the coil. The third wire extends along a length of the pair of signal wires and is configured to reinforce the pair of signal wires.

Abstract: Various embodiments of the present disclosure can include a high-density electrode catheter. In some embodiments, the high-density electrode catheter can include a catheter shaft including a proximal end and a distal end, the catheter shaft defining a catheter shaft longitudinal axis. In some embodiments, the high-density electrode catheter can include a shaft magnetic position sensor disposed along a distal portion of the catheter shaft. In some embodiments, the high-density electrode catheter can include a flexible tip portion located adjacent to the distal end of the catheter shaft, wherein the flexible tip portion includes a flexible framework. In some embodiments, the high-density electrode catheter can include a plurality of electrodes disposed on the flexible framework. In some embodiments, the high-density electrode catheter can include a tip magnetic position sensor disposed on a portion of the flexible framework.
