Abstract
An expandable prosthesis having an imageable structure comprising one or more elements visually distinguishable by an external (e.g., radiographic or ultrasonic) imaging system, the structure being located about a first axis that corresponds to a structural feature of the prosthesis that is configured to perform a specific function particular to that axis. The imageable structure is configured to assist in the rotational orientation of the prosthesis during placement within the implantation site. In one embodiment, the prosthesis comprises a venous valve that includes imageable elements or structure, such as a pair of radiopaque markers, that defines the orifice of the valve structure such that the orifice can be oriented with a particular anatomical feature under imaging, such as to align the orifice with the long axis of the vessel.
