Abstract

A dilation apparatus includes a handle assembly, a dilator, a guidewire, and a steering assembly. The dilator is connected to the handle assembly and is configured to transition between an unexpanded state and an expanded state. The guidewire is longitudinally fixed relative to the dilator. The steering assembly is configured to laterally deflect at least a portion of the guidewire relative to the handle assembly. The steering assembly includes an actuator coupled with the handle assembly and a pull wire extending between the actuator and guidewire. A portion of the pull wire is attached to the guidewire. The actuator is configured to move the pull wire relative to the handle assembly in order to laterally deflect the at least a portion of the guidewire.
