Vascular repair devices

Abstract

A system for implanting a prosthesis includes a prosthesis that extends about a major longitudinal axis and an alignment device connected to the prosthesis. 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.
