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 1):
A stent graft device comprising:\n a stent frame having a central axis; a generally tubular graft member attached to the stent frame, 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 first row of radiopaque makers positioned along only a first portion of a circumference of the stent graft device, each of the radiopaque markers of the first row positioned on one of the stent frame or the graft member; a second row of radiopaque markers positioned along only a second portion of the circumference of the stent graft device, each of the radiopaque markers of the second row positioned on one of the stent frame or the graft member, wherein the first row is axially and circumferentially offset from the second row; and whereby a unique rotational position of the stent graft device is detectable via a pattern formed by the first and second rows of radiopaque markers in an image of the stent graft device.
