Classification: CPC A | IPC A

Claim 0:
1. An apparatus, comprising:
(a) a body that includes an actuation assembly slidably coupled with the body;
(b) a shaft assembly extending distally from the body and defining a longitudinal axis, the shaft assembly including a flexible distal portion, the actuation assembly being configured to translate along the body to distally advance one of a guidewire or a dilation catheter relative to the shaft assembly; and
(c) a deflection actuation assembly, including:
(i) a first rotary actuator,
(ii) a translatable actuation member extending through the shaft assembly, the translatable actuation member being operatively coupled with the first rotary actuator and the flexible distal portion of the shaft assembly, the first rotary actuator being rotatable by a rotational force to thereby drive the translatable actuation member longitudinally, the flexible distal portion being configured to deflect away from the longitudinal axis in response to translation of the translatable actuation member longitudinally, and
(iii) a resilient member positioned between the first rotary actuator and the body, the resilient member being configured to apply a friction force between the first rotary actuator and the body, the friction force being operable to increase the rotational force required to rotate the first rotary actuator.
