    摘要： A deflectable stylet for a catheter includes an elongate deflectable member with a bend-enhancing region defined at a distal part of the deflectable member. An actuator has a distal end. 1 fast with a distal end of the deflectable member, relative displacement between the actuator and the deflectable member causing deflection of the distal part of the deflectable member at the bend-enhancing region. A control member is displaceably arranged relative to the deflectable member, the control member interacting with the bend-enhancing region of the deflectable member for controlling the extent of deflection of the distal part of the deflectable member.
