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; a lower rack; a lower proximal block; 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; and 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, characterized in that: the upper distal block defines a pawl configured to permit only proximal movement in relation to the upper rack; the handle further comprises 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; the lower rack is configured to slide proximally and, alternatingly, distally in relation to the handle; the handle further comprises 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; the lower proximal block is moveable along the lower rack and defines a pawl configured to permit only proximal movement in relation to the lower rack; and the handle further comprises: a beam; an upper distal link connected at a first end to the upper distal block and at a second end to the beam; an upper proximal link connected at a first end to the upper proximal block and at a second end to the beam; a lower distal link connected at a first end to the lower distal block and at a second end to the beam; and a lower proximal link connected at a first end to the lower proximal block and at a second end to the beam. an upper rack fixed to the handle; an upper distal block moveable along the upper rack; a lower rack; a lower proximal block; 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; and 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, the upper distal block defines a pawl configured to permit only proximal movement in relation to the upper rack; the handle further comprises 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; the lower rack is configured to slide proximally and, alternatingly, distally in relation to the handle; the handle further comprises 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; the lower proximal block is moveable along the lower rack and defines a pawl configured to permit only proximal movement in relation to the lower rack; and the handle further comprises: a beam; an upper distal link connected at a first end to the upper distal block and at a second end to the beam; an upper proximal link connected at a first end to the upper proximal block and at a second end to the beam; a lower distal link connected at a first end to the lower distal block and at a second end to the beam; and a lower proximal link connected at a first end to the lower proximal block and at a second end to the beam. a beam; an upper distal link connected at a first end to the upper distal block and at a second end to the beam; an upper proximal link connected at a first end to the upper proximal block and at a second end to the beam; a lower distal link connected at a first end to the lower distal block and at a second end to the beam; and a lower proximal link connected at a first end to the lower proximal block and at a second end to the beam.
