A delivery device for deploying an expandable prosthesis and method of use thereof are described. The delivery device comprises an outer catheter that is capable of retracting in a proximal direction and resheathing over the prosthesis in a distal direction. The device comprises a drive pulley that can engage a particular gear set to retract the outer catheter and expose the prosthesis. The drive pulley can also engage another gear set to resheath the outer catheter and recapture the prosthesis between the inner and the outer catheter. A directional switch enables the device to operate between the two modes.
