Abstract:
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.

Claim (Index 9):
A stent graft device comprising:\n a plurality of stent frame elements arranged along a central axis; a graft member attached with the stent frame elements, wherein the stent graft device has a compressed state and an expanded state, wherein a diameter of the stent graft device in the expanded state is greater than that of the stent graft device in the compressed state; a plurality of rows of radiopaque markers positioned along a circumference of the stent graft device; wherein each of the plurality of rows of radiopaque markers is axially spaced apart from each other of the plurality of rows with respect to the central axis, each of the radiopaque markers is positioned on one of the plurality of stent frame elements or the graft member and each of the plurality of rows has a circumferential length less than a total circumference of the stent graft device; and whereby a unique rotational position of the stent graft device is detectable via a pattern formed by the plurality of rows of radiopaque markers in an image of the stent graft device.
