1. A delivery system for delivering a prosthesis, the delivery system comprising:

  • a housing;

    a sheath extending from within the housing;

    a first rotatable knob accessible from an exterior of the housing;

    a first pulley coupled to the first rotatable knob so as to be rotatable therewith;

    a second rotatable knob accessible from an exterior of the housing;

    a second pulley coupled to the second rotatable knob so as to be rotatable therewith;

    at least one cable coupled to both the first pulley and the second pulley, wherein the at least one cable is coupled to a proximal portion of the sheath and rotation of the first rotatable knob causes the first pulley to rotate while the second pulley remains stationary thereby causing only the first pulley to wind up a portion of the at least one cable and retract the sheath at a, first speed, and rotation of the second rotatable knob causes both the first and second pulleys to rotate, thereby causing both the first and second pulleys to wind up a portion of the at least one cable and retract the sheath at a second speed, the second speed being faster than the first speed.
