1. A stent loading and delivery device comprising:

  • a handle assembly;

    an outer tubular member extending distally from the handle assembly, the outer tubular member having a proximal end and a distal end, the proximal end of the outer tubular member attached to a first handle of the handle assembly;

    an intermediate tubular member slidably disposed within the outer tubular member, the intermediate tubular member having a proximal end and a distal end, the proximal end of the intermediate tubular member attached to a second handle of the handle assembly;

    an inner elongate member extending distally from the handle assembly within the intermediate tubular member, the inner elongate member having a proximal end and a distal end, the proximal end of the inner elongate member attached to a third handle of the handle assembly; and

    a stent constrainment mechanism attached to the distal end of the intermediate tubular member, the stent constrainment mechanism configured to receive a proximal portion of a stent into a distal opening of the stent constrainment mechanism in an expanded state, wherein upon longitudinal actuation of the outer tubular member relative to the intermediate tubular member the stent constrainment mechanism is configured to be collapsed radially inward around the stent to constrain the stent within the outer tubular member.
