Claim:
1. A handle positioned at a proximal end of a catheter for delivering, from a distal end of the catheter, a stent positioned within a sheath, the handle comprising: an upper rack fixed to the handle; an upper distal block moveable along the upper rack and defining a pawl configured to permit only proximal movement in relation to the upper rack; an upper proximal block moveable along the upper rack and defining a pawl configured to permit only proximal movement in relation to the upper rack; a lower rack configured to slide proximally and, alternatingly, distally in relation to the handle; a lower distal block moveable along the lower rack and defining a pawl configured to permit only proximal movement in relation to the lower rack; a lower proximal block moveable along the lower rack and defining a pawl configured to permit only proximal movement in relation to the lower rack; wherein, the upper distal block is operably connected to a proximal end of a sheath actuator, a distal end of the sheath actuator being operably connected to the sheath; wherein, the lower proximal block is operably connected to a proximal end of a stent actuator, a distal end of the stent actuator being operably connected to a stent engagement member.
