Claim 23:
24. A method of controlling an ultrasound imaging transducer, the method comprising:
advancing a distal end region of a catheter assembly to an anatomical region of interest, the catheter assembly comprising a) a rotatable shaft carrying an ultrasound imaging transducer, and b) a deflectable shaft;
actuating a first actuator of a handle assembly to cause rotational movement of the rotatable shaft relative to the deflectable shaft, which thereby causes rotational movement of the ultrasound imaging transducer; and
actuating a second actuator of the handle assembly to cause deflection of the deflectable shaft,
wherein the handle assembly comprises a handle body with an outer surface that can be gripped by a user,
wherein the first actuator and the second actuator are circumferentially disposed about a longitudinal axis of the handle body, and
wherein one or more of the actuating of the first actuator or the actuating of the second actuator causes a tool lock disposed within the body of handle to constrain movement of one or more of the rotatable shaft or the deflectable shaft, wherein the tool lock comprises a friction fit with features of the handle assembly such that the tool lock is moveable but does not move back to an original position except by action of a user.
