| 摘要 |
A delivery device (100) for deploying an expandable prosthesis and method of use thereof are described. The delivery device includes an outer sheath (1200) that is capable of retracting in a proximal direction and resheathing over the prosthesis in a distal direction. The device includes a drive pulley (901) that can engage gears (503,402) to retract or resheath the outer catheter in relation to the prosthesis. In some embodiments, the delivery device may include a reinforced outer sheath (3300) disposed over an inner elongate member, the reinforced outer sheath comprising a proximal section (3301) reinforced with a braid, a distal section (3302) reinforced with a coil and an overlapping (3303) section extending between the proximal section and the distal section. Additionally or alternatively, the delivery device may include a stabilizing element (290) for releasably holding the stent (301) to the inner catheter. |
