1. A delivery system to sheathe a stent and deploy the stent within a lumen of a body of a patient, the delivery system comprising:

  • a delivery device that is configured to deploy a stent within the lumen of the body of a patient, the delivery device including a tubular member that comprises an outer sheath and an inner member;

    a translational member that is axially displaceable relative to the tubular member of the delivery device, the translational member comprising a tapered member disposed at a distal end of the translational member to translate axial movement of the translational member in a distal direction along the tubular member into radial force to compress and thereby crimp an unsheathed portion of the stent; and

    a plurality of sheathing fingers configured to crimp and sheathe an unsheathed portion of the stent, wherein the plurality of sheathing fingers are configured to engage the outer sheath of the tubular member of the delivery device and to engage the translational member as the translational member is moved distally along the tubular member of the delivery device, wherein distal movement of the translational member moves the plurality of sheathing fingers, which engage the outer sheath of the tubular member to move the outer sheath distally relative to a crimped portion of the stent to thereby sheathe the crimped portion of the stent.
