Abstract
The distal end of the catheter can be constructed to include one or more features to provide strain relief to wiring of multiple single axis sensors. In some examples, the multiple single axis sensors and associated wiring can be manufactured over a flexible tube that can be placed over a movable support member. In some examples, wiring can be wound an increased number of consecutive traverse turns on a distal and/or proximal side of a single axis sensor, and a shrink sleeve may be positioned over the traverse turns. In some examples a wire shield transition point can be positioned on a straight portion in a proximal direction to the distal portion of the catheter.
