1. A system for implanting a prosthesis, comprising:

  • a) a prosthesis that is asymmetric about a major longitudinal axis; and

    b) a flexible prosthesis delivery sheath in direct contact with and constraining the prosthesis for delivering the prosthesis to a treatment site; and

    c) an alignment device connected to the flexible prosthesis delivery sheath, the alignment device appearing asymmetric across a plane coplanar to a longitudinal axis of the flexible prosthesis delivery sheath when viewed both along the plane and transversely to the longitudinal axis of the flexible prosthesis delivery sheath, the alignment device also lying in a plane parallel to and spaced apart from the longitudinal axis of the flexible prosthesis delivery sheath, and wherein the alignment device is visible to a user, thereby indicating a rotational and an axial position of the flexible prosthesis delivery sheath and the prosthesis with respect to the treatment site prior to implantation of the prosthesis at the treatment site.
