Abstract
Devices and methods are provided for operating and controlling an interventional element on an interventional catheter. The interventional element may be a stent or series of stents, a balloon, or any other interventional element for which length control is necessary or desirable. A handle member includes an elongated body and an actuator knob that rotates around the longitudinal axis of the body. Rotational movement of the actuator knob is translated to rotational movement of one or more lead screws by a system of gears, rollers, or combinations of gears and rollers. Each of one or more axially moveable members is positioned on a lead screw and attached to a portion of the catheter shaft in order to provide the ability to advance or retract the portion of the catheter shaft.
