1. A stent delivery system, comprising:
- a hub coupled to an outer tube;
a slider coupled to the hub, the slider disposed over a track fixed to a housing, the track comprising a pair of parallel rails, the slider having a first position corresponding to a distal position of the outer tube constraining a stent, and a second position corresponding to a proximal position of the outer tube releasing the stent, the slider having a portion protruding outside of the housing enabling manual movement of the slider to the second position;
a pull wire having a first end attached to the slider and a second end coupled to a take-up reel; and
a trigger biased to a rest position by a leaf spring mounted to the housing, wherein actuation of the trigger incrementally moves the slider along the track.
