The alignment device appears asymmetric across a plane coplanar to a longitudinal axis of the prosthesis when viewed both along the plane and transversely to the longitudinal axis of the prosthesis delivery and also lies in a plane parallel to and spaced apart from the longitudinal axis of the prosthesis. The alignment device is visible to a user, thereby indicating a rotational and an axial position of the prosthesis with respect to the treatment site prior to implantation of the prosthesis at a treatment site. In an embodiment, the system includes a guidewire catheter that is asymmetric along a major longitudinal axis. ## Claims ### Claim 1 A system for implanting a prosthesis, comprising: a) a prosthesis extending about a major longitudinal axis; and b) an alignment device connected to the prosthesis, the alignment device appearing asymmetric across a plane coplanar to a longitudinal axis of the prosthesis when viewed both along the plane and transversely to the longitudinal axis of the prosthesis delivery, the alignment device also lying in a plane parallel to and spaced apart from the longitudinal axis of the prosthesis, and wherein the alignment device is visible to a user, thereby indicating a rotational and an axial position of the prosthesis with respect to the treatment site prior to implantation of the prosthesis at the treatment site. ### Claim 2 (depends on 1) The system according to claim 1, wherein the alignment device is of a radiopaque material and is visible to the user when irradiated. ### Claim 3 (depends on 1) The system according to claim 1, wherein the alignment device is of an ultrasound-reflecting material and is visible to the user when exposed to ultrasound stimulation. ### Claim 4 (depends on 1) The system of claim 1, wherein the alignment device is a D-shaped alignment device. ### Claim 5 (depends on 4) The system of claim 4, wherein the D-shaped alignment device is radiopaque. ### Claim 6 (depends on 1) The system of claim 1, wherein the prosthesis includes a longitudinal support member positioned asymmetrically about the major longitudinal axis of the prosthesis. ### Claim 7 A system for implanting a prosthesis, comprising: a) a guidewire catheter that is asymmetric about a major longitudinal axis; b) a prosthesis extending about the guidewire catheter; and c) an alignment device connected to the prosthesis, the alignment device appearing asymmetric across a plane coplanar to a longitudinal axis of the prosthesis when viewed both along the plane and transversely to the longitudinal axis of the prosthesis, the alignment device also lying in a plane parallel to and spaced apart from the longitudinal axis of the prosthesis. ### Claim 8 (depends on 7) The system according to claim 7, wherein the alignment device is of a radiopaque material and is visible to the user when irradiated. ### Claim 9 (depends on 7) The system according to claim 7, wherein the alignment device is of an ultrasound-reflecting material and is visible to the user when exposed to ultrasound stimulation. ### Claim 10 (depends on 7) The system of claim 7, wherein the alignment device is a D-shaped alignment device. ### Claim 11 (depends on 10) The system of claim 10, wherein the D-shaped alignment device is radiopaque. ### Claim 12 (depends on 7) The system of claim 7, wherein the prosthesis includes a longitudinal support member positioned asymmetrically about the major longitudinal axis of the prosthesis.
