Abstract
A delivery device for deploying an expandable prosthesis and method of use thereof are described. The delivery device includes an outer sheath that is capable of retracting in a proximal direction and resheathing over the prosthesis in a distal direction. The device includes a drive pulley that can engage gears to retract or resheath the outer catheter in relation to the prosthesis. In some embodiments, the delivery device may include a reinforced outer sheath disposed over an inner elongate member, the reinforced outer sheath comprising a proximal section reinforced with a braid, a distal section reinforced with a coil and an overlapping section extending between the proximal section and the distal section. Additionally or alternatively, the delivery device may include a stabilizing element for releasably holding the stent to the inner catheter.
