A steerable catheter assembly (20) includes a flexible, elongated catheter body (30) having a proximal end (24), and a distal end (28), the distal end (28) of the catheter body (30) having at least one deflectable segment (36) having a distal end, and a proximal end (42). A support hub (32) is disposed at the proximal end (42) of the deflectable segment (36), and a deflection mechanism comprising an actuating assembly is disposed at the proximal end (24) of the catheter body (30). The actuating assembly is operatively attached to the deflectable segment (36), an actuator line (52) attached at its proximal end (54) to the actuating assembly, and attached at its distal end at the distal end of the deflectable segment (36). The actuator line (52) passes through the support hub (432). An actuator ribbon (60) is attached at its proximal end to the support hub (32), and is attached at its distal end at the distal end of the deflectable segment (36). |
