Claim 12:
13. A method comprising:
coupling an elongated implement at a proximal end thereof to an actuator that is movable along an axis; and
motivating the implement by rotatably moving the actuator in reference to a guide through a generally helical path around the axiscreated by the guide, the helical path having a pitch that is varied along a length of the guide to change a distance traveled by the actuator along the axis per unit of rotation of the actuator as the actuator travels distally relative to the guide,
wherein the pitch is varied to reduce a distance traveled by the actuator along the axis per unit of rotation of the actuator at a position at which the implement is anticipated to exert an increased resistance on the actuator to movement along the axis, and
wherein the position at which the elongated implement is anticipated to exert the increased resistance corresponds to a location at which a configuration of a distal portion of the implement resists movement of the implement.
