Disclosed herein are devices and methods for insertion into a passageway. In one aspect, a device includes a tube having a movable actuator mechanism located at the proximal end thereof and a balloon is disposed on a distal end thereof. The balloon can be coupled to the movable actuator mechanism such that movement of the actuator mechanism results in movement of a portion of the balloon between a first insertion position where the balloon is adapted for insertion into and through the passageway and a second inflation position where the balloon is adapted so as to allow for its inflation.
