An apparatus provided by the present invention includes a main body, a shaft assembly, a deflection actuation assembly and a dilation catheter. The shaft assembly includes a rigid proximal portion anda flexible distal portion, and the deflection actuation assembly includes a rotary actuator and a first translatable actuation member at least partially disposed within the first rotary actuator. A second translatable actuation member extends through the shaft assembly and couples the first translatable actuation member with the flexible distal portion of the shaft assembly, and the first rotaryactuator is rotatable about a longitudinal axis to thereby drive the first and second translatable actuation members longitudinally. The flexible distal portion is configured to deflect away from thelongitudinal axis in response to the translation of the first and second translatable actuation members longitudinally, and the dilation catheter is slidable relative to the shaft assembly and includes an expandable dilator. 本发
