17. A method of manufacturing a medical instrument, the medical instrument including a shaft assembly having a first tube, a second tube, and a position sensor, the first tube extending from a proximal first end portion to a distal first end portion, the second tube extending from a proximal second end portion to a distal second end portion, the method comprising:
engaging a die against the distal first end portion of the first tube while simultaneously moving the die relative to the distal first end portion of the first tube along a predetermined path thereby forming the distal first end portion with a predetermined shape;
inserting the second tube into the first tube such that an inner radial surface of the distal first end portion engages an outer radial surface of the second tube;
positioning the position sensor on the distal second end portion of the second tube; and
welding a distal end of the first tube to the distal end of the second tube at a location distal of the position sensor to define a single seam.
