1. A vascular intervention device delivery system comprising:

  • a handle that includes a catch positioned therein;

    a pivot plate mounted in the handle, and being pivotable about a first axis with respect to the handle between a locked position and an unlocked position, and the pivot plate supporting an axle that defines a second axis;

    a thumbwheel rotatably mounted on the axle and having a radially outward thumb surface and a radially outward toothed surface;

    wherein the radially outward toothed surface is in contact with the catch when the pivot plate is at the locked position to prevent rotation of the thumbwheel in a forward direction, and the radially outward toothed surface is out of contact with the catch when the pivot plate is at the unlocked position to permit rotation of the thumbwheel in a reverse direction;

    a catheter with a proximal end attached to the handle, and a distal carrier segment for mounting a vascular intervention device thereon;

    a retractable sheath movable from a first position covering the distal carrier segment, to a second position retracted proximally uncovering the distal carrier segment;

    a pull extending between the thumbwheel and the retractable sheath; and

    the retractable sheath moving responsive to rotation of the thumbwheel in the reverse direction.
