1. A delivery system for a valve prosthesis configured for delivery within a vasculature, the delivery system comprising:

  • an outer shaft defining a lumen and at least two windows formed through a sidewall thereof;

    an inner shaft concentrically disposed within the lumen of the outer shaft, the inner shaft having a distal portion being configured to receive the valve prosthesis thereon; and

    at least one centering mechanism including at least two wings disposed at circumferentially spaced-apart locations along the delivery system, a first end of each wing being attached to the inner shaft and a second end being free to slide over the inner shaft, wherein when the centering mechanism is in a delivery configuration each wing is circumferentially offset from one of the windows of the outer shaft and has a straightened profile that is enclosed between the outer and inner shafts and when the centering mechanism is in an expanded configuration each wing has a curved, bowed profile and is aligned with and radially extends through one of the windows of the outer shaft,wherein the outer shaft is rotated in order to alternate the centering mechanism between the delivery configuration and the expanded configuration.
