Abstract

Claims (33)

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.

2. The intraluminal device of claim 1 , wherein the first radiopaque marker and the second radiopaque marker include at least one of a tungsten material, platinum, or iridium.

3. The intraluminal device of claim 1 , wherein the first radiopaque marker and the second radiopaque marker comprise a plurality of radiopaque coils.

4. The intraluminal device of claim 1 , wherein each of the first radiopaque marker and the second radiopaque marker comprises only one second segment.

5. The intraluminal device of claim 1 ,

wherein the flexible elongate member includes an inner tubular member and an outer tubular member extending between the proximal portion and the distal portion, and

wherein the first radiopaque marker and the second radiopaque marker are positioned between the inner tubular member and the outer tubular member at the distal portion.

6. The intraluminal device of claim 5 ,

wherein the first segment of at least one of the first radiopaque marker or the second radiopaque marker is positioned around a portion of an outer diameter of the inner tubular member, and

wherein the second segment of the at least one of the first radiopaque marker or the second radiopaque marker extends along an outer wall of the inner tubular member.

7. The intraluminal device of claim 5 , wherein at least portions of the first radiopaque marker and the second radiopaque marker are thermally bonded to at least an outer wall of the inner tubular member.

8. The intraluminal device of claim 5 , wherein at least portions of the first radiopaque marker and the second radiopaque marker are thermally bonded to an outer wall of the inner tubular member and an inner wall of the outer tubular member.

9. The intraluminal device of claim 5 , wherein the first radiopaque marker and the second radiopaque marker are swaged onto at least an outer wall of the inner tubular member by an adhesive.

10. The intraluminal device of claim 5 , wherein the first radiopaque marker and the second radiopaque marker are bonded to at least an outer wall of the inner tubular member by an adhesive.

11. The intraluminal device of claim 5 , further comprising a flexible element extending along the flexible elongate member such that the flexible element is distinct from the flexible elongate member, wherein the first radiopaque marker and the second radiopaque marker are attached to the flexible element.

12. The intraluminal device of claim 11 , wherein the flexible element is a wire extending along a length between the inner tubular member and the outer tubular member.
