A method of delivering a rigid intravascular device to a target location in a patient's heart includes positioning a distal tip of an elongated member of the intravascular device delivery system in a right atrium of a heart and moving the distal tip of the elongated member into a left atrium of the heart. The method includes advancing an inner steerable catheter of the elongated member longitudinally distally relative to an outer sleeve of the elongated member a first longitudinal distance; deflecting at least a portion of the inner steerable catheter a first deflection amount; then advancing an inner steerable catheter of the elongated member longitudinally distally relative to an outer sleeve of the elongated member a second longitudinal distance; and then deflecting at least a portion of the inner steerable catheter a second deflection amount.
