Patent ID: 11026821

Abstract:
A stent delivery device includes a sheath covering a compressed stent and a housing. The housing includes a mover reel coupled to an actuator that rotates the mover reel in a winding direction when actuated. A sheath pull wire is coupled to the mover reel and the sheath. Rotation of the mover reel in the winding direction winds the sheath pull wire on the mover reel and moves the sheath in a proximal direction. A pre-mover is provided separate from the actuator, the pre-mover including an arm having a proximal end engaged with the mover reel to prevent rotation in the locked position. The pre-mover includes a pre-mover actuator coupled to the arm and having a portion projecting outside of the housing, wherein movement of the pre-mover actuator disengages the arm from the mover reel and rotates the mover reel a predetermined amount in the winding direction.
