1. A method of implanting a prosthesis in a patient at a treatment site within a blood vessel, comprising the steps of:

  • a) advancing an outer catheter of a prosthesis delivery system in the patient distal to the treatment site, the outer catheter defining an inside diameter and wherein the treatment site is a curved portion of the aortic arch;

    b) advancing an inner sheath containing a prosthesis that is asymmetric about a major longitudinal axis, the inner sheath having greater flexibility than the outer catheter and an outside diameter that is greater than the inside diameter of the outer catheter, and a guidewire lumen of the delivery system from the outer catheter and then through the curved portion of the aortic arch along a guidewire while the outer catheter remains stationary relative to the patient, whereby advancement of the inner sheath and the guidewire lumen delivers the prosthesis to a position within the curved portion of the aortic arch and causes rotational alignment of the prosthesis within the curved portion of the aortic arch;

    c) retracting the inner sheath to deploy the prosthesis from within the inner sheath at the curved portion of the aortic arch; and

    d) retracting the delivery system from the patient.
