1. A method of delivering a valve prosthesis configured for delivery within a vasculature, the method comprising the steps of:

  • percutaneously introducing a valve centering catheter into a vasculature, the valve centering catheter having a circumferential centering device at a distal portion thereof, wherein the circumferential centering device is in a delivery configuration;

    tracking the valve centering catheter through the vasculature until the circumferential centering device is positioned at a treatment site;

    radially expanding the circumferential centering device into an expanded configuration at the treatment site, wherein the circumferential centering device has an outer wall and an inner wall with an interior space being defined between the outer wall and the inner wall, the inner wall defining a central opening there-through when in the expanded configuration;

    percutaneously introducing a valve delivery system into the vasculature after the circumferential centering device has been radially expanded, the valve delivery system having a valve prosthesis at a distal portion thereof, wherein the valve prosthesis is in a delivery configuration;

    tracking the valve delivery system through the vasculature until the valve prosthesis is positioned through the central opening of the expanded circumferential centering device in order to circumferentially center the valve prosthesis within the native anatomy of the treatment site; and

    deploying at least an inflow end of the valve prosthesis into apposition with the native anatomy of the treatment site while at least a portion of the valve prosthesis remains in the delivery configuration and positioned through the central opening of the expanded circumferential centering device, thereby anchoring and securing the circumferentially centered position of the valve prosthesis within the native anatomy of the treatment site.
