Abstract:
1. A handle assembly, comprising: a housing; a rotator coupled to a proximal region of an elongated flexible shaft extending rotatably along an axis and having a deflectable distal region configured for intravascular delivery to a blood vessel of a human patient, wherein the rotator is configured to rotate the entire elongated flexible shaft through the proximal region without rotating the housing; a rotational limiting element configured to prevent rotation of the elongated flexible shaft and the rotator beyond a predetermined number of rotations; and an actuator coupled to a carrier, which in turn is coupled to a control wire extending within a lumen of the elongated flexible shaft to the deflectable distal region such that the actuator is operatively connected to the deflectable distal region of the elongated flexible shaft; wherein the actuator is configured to rotate relative to the housing, and wherein the carrier is coupled to the actuator in a manner that converts rotation of the actuator into translation of the carrier, and
