A deflectable stylet (10) for a catheter includes an elongate deflectable member (12) with a bend-enhancing region (20) defined at a distal part of the deflectable member (12). An actuator (16) has a distal end (16.1) fast with a distal end (12.1) of the deflectable member (12), relative displacement between the actuator (16) and the deflectable member (12) causing deflection of the distal part of the deflectable member (12) at the bend-enhancing region (20). A control member (18) is displaceably arranged relative to the deflectable member (12), the control member (18) interacting with the bend-enhancing region (20) of the deflectable member (12) for controlling the extent of deflection of the distal part of the deflectable member (12). |
