Claims
- 1. A stent comprising:a member having opposite free ends and formed of a sheet of biocompatible material having a pattern in a surface of said sheet, said pattern including in said sheet a plurality of cells, said pattern further including an eyelet at at least one of said free ends of said member, said eyelet being of a fixed size smaller than a respective said cell, and wherein a radiopaque marker is positioned in said eyelet to clearly indicate a location of the at least one free end.
- 2. The stent of claim 1 wherein said radiopaque marker comprises a radiopaque material from a group consisting of at least one of gold, platinum, tungsten, or iridium.
- 3. The stent of claim 2 wherein said radiopaque material is melted into position in said eyelet and extends across an opening through said eyelet.
- 4. The stent of claim 2 wherein said radiopaque material is crimped into position in said eyelet and extends across an opening through said eyelet.
- 5. The stent of claim 1 further comprising a coating material over at least one of said sheet of biocompatible material and said radiopaque marker.
- 6. The stent of claim 5 wherein said coating material comprises at least of a group consisting of parylene, polytetrafluoroethylene, or an antithrombotic material.
- 7. The stent of claim 5 wherein said coating material has a coefficient of friction less than a coefficient of friction of at least one of said sheet of biocompatible material and said radiopaque marker.
- 8. The stent of claim 1 wherein at least one of said sheet of biocompatible material and said radiopaque marker has a predetermined surface energy density.
- 9. The stent of claim 1, wherein said sheet of biocompatible material includes a seamless sheet of biocompatible material.
- 10. The stent of claim 1, wherein said pattern further includes radiopaque markers at both said free ends of the stent.
- 11. The stent of claim 1, wherein said eyelet is a closed ring.
- 12. The stent of claim 1, wherein the eyelet is defined by an opening through a thickness of said sheet.
- 13. A tubular-shaped stent comprising:a sheet of biocompatible material having a tubular shape and a pattern in a surface of said sheet, said pattern including a plurality of cells in said surface of said sheet; said sheet includes an eyelet at at least one free end of said pattern that is defined by an opening through a thickness of said sheet, said eyelet being of a fixed size smaller than a respective said cell and a radiopaque marker at said at least one free end of said sheet and positioned in said eyelet to clearly indicate a location of the at least one free end.
- 14. The tubular-shaped stent of claim 13 further comprising another radiopaque marker at an other of said free ends of said sheet.
- 15. The tubular-shaped stent of claim 13 wherein said radiopaque marker includes a radiopaque material.
- 16. The tubular-shaped stent of claim 15 wherein said radiopaque material comprises at least one of a group consisting of gold, platinum, tungsten, or iridium.
- 17. The tubular-shaped stent of claim 15 further comprising a coating material posited over said radiopaque material.
- 18. The tubular-shaped stent of claim 17 wherein said coating material comprises at least one of a group consisting of parylene, polytetrafluoroethylene, or an antithrombotic material.
- 19. The tubular-shaped stent of claim 13 wherein said radiopaque marker comprises gold melted into position in said eyelet and extends across an opening through said eyelet.
- 20. The tubular-shaped stent of claim 13 wherein said radiopaque marker comprises gold crimped into position into said eyelet and extends across an opening through said eyelet.
- 21. The tubular-shaped stent of claim 13, wherein said sheet of biocompatible material includes a seamless sheet of biocompatible material.
- 22. The tubular-shaped stent of claim 13, wherein said pattern further includes radiopaque markers at both said free ends of the stent.
- 23. The tubular-shaped stent of claim 13, wherein said eyelet is a closed ring.
