- 8. The intraluminal medical device according to claim 7, wherein the marker insert is secured in the marker housing by a protruding ridge.
- 9. An intraluminal medical device comprising:
a thin-walled, substantially tubular member having open ends, and a first diameter for insertion into a lumen of a vessel and a second diameter for anchoring in the lumen of the vessel, the thin-walled tubular member comprising a superelastic alloy; and at least one marker connected to at least one end of the thin-walled, substantially tubular member, the at least one marker comprising a marker housing having a substantially circular shape with flattened sections and a marker insert, both having a radius of curvature equal to the radius of curvature of the substantially tubular member.
- 10. The intraluminal medical device according to claim 9, wherein the marker housing comprises the same material as the intraluminal medical device and is integral thereto, thereby forming a unitary structure.
- 11. The intraluminal medical device according to claim 10, wherein the marker housing defines a substantially elliptical open having a predetermined curvature.
- 12. The intraluminal medical device according to claim 11, wherein the marker insert comprises a material having a radiopacity higher than that of the material comprising the intraluminal medical device.
- 13. The intraluminal medical device according to claim 12, wherein the marker insert comprises Tantalum.
- 14. The intraluminal medical device according to claim 13, wherein the marker insert has a curvature equal to that of the curvature of the opening in the marker housing.
- 15. The intraluminal medical device according to claim 14, wherein the marker insert has a diameter of 0.02 inches.
- 16. The intraluminal medical device according to claim 15, wherein the marker insert is secured in the marker housing by frictional, locking engagement.
- 17. The intraluminal medical device according to claim 16, wherein the marker insert is secured in the marker housing by a protruding ridge.
- 18. A stent comprising:
a thin-walled, substantially tubular member having open ends, and a first diameter for insertion into a lumen of a vessel and a second diameter for anchoring in the lumen of the vessel, the thin-walled tubular member comprising a superelastic alloy; and at least one marker connected to at least one end of the thin-walled, substantially tubular member, the at least one marker comprising a marker housing having a substantially circular shape with flattened sections and a marker insert, both having a radius of curvature equal to the radius of curvature of the substantially tubular member.
- 19. The stent according to claim 18, wherein the marker housing comprises the same material as the stent and is integral thereto, thereby forming a unitary structure.
- 20. The stent according to claim 19, wherein the marker housing defines a substantially elliptical open having a predetermined curvature.
- 21. The stent according to claim 20, wherein the marker insert comprises a material having a radiopacity higher than that of the material comprising the stent.
- 22. The stent according to claim 21, wherein the marker insert comprises Tantalum.
- 23. The stent according to claim 22, wherein the marker insert has a curvature equal to that of the curvature of the opening in the marker housing.
- 24. The stent according to claim 23, wherein the marker insert has a diameter of 0.02 inches.
- 25. The stent according to claim 24, wherein the marker insert is secured in the marker housing by frictional, locking engagement.
- 26. The intraluminal medical device according to claim 25, wherein the marker insert is secured in the marker housing by a protruding ridge.
- 27. The stent according to claim 18, further comprising six markers attached to each end of the thin-walled, substantially tubular member.
- 28. An intraluminal medical device comprising:
a substantially tubular member having open ends, and a first diameter for insertion into a lumen of a vessel and a second diameter for anchoring in the lumen of the vessel; and at least one marker connected to at least one end of the substantially tubular member, the at least one marker comprising a marker housing having a substantially oval shape and a marker insert having a substantially oval shape, both having a radius of curvature equal to the radius of curvature of the substantially tubular member.
