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 one window 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 one coiled wing, a first end of the at least one coiled wing being attached to the inner shaft and a second end of the at least one coiled wing being unattached to inner shaft, wherein when the at least one centering mechanism is in a delivery configuration, the at least one coiled wing has a series of windings that extend around the inner shaft such that each winding is enclosed between the outer and inner shafts and when the at least one centering mechanism is in an expanded configuration, the at least one coiled wing extends through the at least one window of the outer shaft and has a series of windings that extend around the outer shaft.
