A control system for controlling movement of a stent delivery system, a stent delivery system and a method for controlling movement of a stent delivery system are provided. The control system includes a housing having a chamber formed therein, a first drive at least partially positioned within the housing and operably connected to the first shaft of the delivery system and a second drive at least partially positioned within the housing and operably connected to the second shaft. The control system also includes a pressure controller operably connected to the housing and configured to change the pressure within the chamber. The first drive and the second drives are movable in response to the pressure change within the chamber and movement of the second drive relative to the first drive causes the second shaft to move relative to the first shaft to expand or constrain a stent operably connected thereto.
