Patent ID: 8506562

Claim:
A deflectable stylet for a catheter, the deflectable stylet including: an elongate deflectable member with a bend-enhancing region defined at a distal part of the elongate deflectable member; an actuator having a distal end fast with a distal end of the elongate deflectable member, relative displacement between the actuator and the elongate deflectable member causing deflection of the distal part of the elongate deflectable member at the bend-enhancing region; a control member axially displaceable relative to the elongate deflectable member, wherein the control member inhibits bending of a longitudinally overlapping portion of the bend-enhancing region, wherein axial displacement of the control member controls the extent of longitudinal overlap between the control member and the bend-enhancing region; and a deflection control mechanism connectable to a proximal end of a catheter handle of the catheter, the deflection control mechanism being coupled to the control member thereby to control axial displacement of the control member relative to the elongate deflectable member, the deflection control mechanism being further coupled to the actuator, wherein the deflection control mechanism is configured to be selectively detachable from and re-attachable with the proximal end of the catheter handle, and the deflection control mechanism further comprises: a mounting formation mounting one of the elongate deflectable member and the actuator to the deflection control mechanism; and an anchoring formation anchoring the other of the elongate deflectable member and the actuator to the deflection control mechanism, wherein the mounting formation is displaceably arranged relative to the deflection control mechanism and the anchoring formation during use of the deflectable stylet.
