1. An intraluminal device comprising:
a flexible elongate member including a proximal portion and a distal portion;
an imaging component coupled to the distal portion of the flexible elongate member; and
a first radiopaque marker and a second radiopaque marker positioned at the distal portion of the flexible elongate member,
wherein the first radiopaque marker and the second radiopaque marker are separated from each other,
wherein each of the first radiopaque marker and the second radiopaque marker includes:
a first segment extending around only part of a circumference of the flexible elongate member, the first segment comprising a first end, a second end, and a first length extending between the first end and the second end; and
a second segment extending longitudinally from the first segment and around only a part of the circumference of the flexible elongate member, the second segment comprising a second length smaller than the first length, wherein the second segment is connected only to the first segment and the flexible elongate member,
wherein the first radiopaque marker and the second radiopaque marker:
comprise a different structure than one another; and
are positioned proximate to one another along a length of the flexible elongate member at the distal portion of the flexible elongate member,
wherein the different structure than one another comprises:
in the first radiopaque marker, the second segment extends longitudinally from a center of the first segment; and
in the second radiopaque marker, the second segment extends longitudinally from the first end of the first segment,
such that the second segment of the first radiopaque marker and the second segment of the second radiopaque marker are offset from one another,
wherein the first segment of the first radiopaque marker is aligned with the first segment of the second radiopaque marker such that
the first end in the first radiopaque marker is aligned with the first end in the second radiopaque marker; and
the second end in the first radiopaque marker is aligned with the second end in the second radiopaque marker.
