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.
