Zusammenfassung:	A steering assembly for an intravascular catheter system includes first and second pull wires, a steering knob, and first and second movers. The intravascular catheter system includes a handle assembly having a longitudinal axis and a balloon catheter having a catheter shaft with a distal end. The first and second pull wires extend between the handle assembly and the distal end of the catheter shaft. The first mover includes a knob engager that engages an internal thread of the steering knob so that rotation of the steering knob about the longitudinal axis moves the first mover in a first direction. The second mover is coupled to the first mover so that the second mover moves in a second direction. Movement of the first and second movers moves the first and second pull wires to articulate a portion of the balloon catheter near the distal end of the catheter shaft.
