摘要:
A stent graft device having a plurality of axially offset rows of radiopaque markers for rotational orientation of the stent graft device. The stent graft device may include an expandable stent frame and attached graft member. Each row of radiopaque markers may include a plurality of radiopaque markers that are evenly spaced. Each row may also include a length that covers a limited portion of the circumference of the stent graft device, where each row is circumferentially offset such that a fluoroscopic projection of the stent graft device illustrates one of a plurality of unique visual orientations of the axially offset rows for use in visually determining a current rotational orientation of the stent graft device.
