1. An apparatus for maneuvering an instrument catheter, the apparatus comprising:

  • a flexible body having a lumen therethrough and a deflection wire, the flexible body having a distal end portion and a proximal end portion, with the distal end portion operably coupled to the deflection wire;

    a handle that extends along a longitudinal axis, the handle coupled to the proximal end portion of the flexible body, the handle comprising;

    a first actuator;

    a second actuator;

    a handle grip;

    a handle lumen extending through the first actuator, the second actuator, and the handle grip, wherein the first actuator and the second actuator are independently rotatable about the longitudinal axis and are disposed longitudinally adjacent with respect to one another;

    a slide operably coupled to the first actuator and to the deflection wire; and

    a rotation assembly operably coupled to the second actuator, the rotation assembly having a tube extending therethrough, the tube being coupled to the rotation assembly and the tube having an inner surface capable of being fixedly attached to an instrument catheter; and

    a continuous lumen extending from the distal end portion of the flexible body to the proximal end of the tube, the continuous lumen comprising the lumen of the flexible body, the handle lumen, and the tube;

    an instrument catheter disposed within the continuous lumen, wherein the instrument catheter is coaxial with the first actuator and the second actuator;

    wherein rotating the first actuator engages the slide causing the slide to displace axially imparting a tensile force to the deflection wire thereby causing the distal end portion of the flexible body to deflect and thereby a distal end portion of the instrument catheter to deflect, and rotation of the second actuator imparts a torque to the tube of the rotation assembly causing the tube to rotate about the longitudinal axis of the handle and thereby rotate the received instrument catheter.
