Abstract

A stent comprises a plurality of segments, including at least one segment which is in the form of a coil and at least one segment which is in a form other than a coil and which is balloon expandable or self-expandable.

Claims

1. A stent comprising a plurality of segments, including at least one segment which is in the form of a coil and at least one segment which is in a form other than a coil and which is balloon expandable or self-expandable.

2. The stent of claim 1 having a first end segment and a second end segment, wherein each of the first and second end segments is in a form other than a coil and is balloon expandable or self-expandable.

3. The stent of claim 2 comprising only one segment which is in the form of a coil and which connects the first and second end segments.

4. The stent of claim 3 wherein the first and second end segments are self-expandable.

5. The stent of claim 4 wherein the first and second end sections are each formed of a plurality of braided filaments.

6. The stent of claim 5 wherein the filaments are made of spring steel.

7. The stent of claim 3 wherein the first and second end segments are balloon expandable.

8. The stent of claim 7 wherein the first and second end segments are each in the form of a tube comprising a plurality of interconnected serpentine segments.

9. The stent of claim 1 wherein the segment which is in the form of a coil is made of spring steel.

11. The stent of claim 9 wherein the tubular, non-coil segment is balloon expandable.

12. The stent of claim 9 wherein the tubular, non-coil segment is self-expandable.

13. The stent of claim 9 having a first end and a second end, the first end being a tubular, non-coil segment and the second end being a tubular, non-coil segment.

10. A stent comprising a coil segment and a tubular, non-coil segment.

14. The stent of claim 10 where the coil segment is made of spring steel.

15. The stent of claim 10 wherein the coil segment has an outer diameter of no more than 6 mm when deployed.

16. The stent of claim 15 having an outer diameter of no more than 6 mm when deployed.

17. The stent of claim 15 having a length of no more than 20 mm.

18. A method of treating a bodily vessel comprising the steps of:

providing a catheter, the catheter including a stent, the stent having a coil segment and at least one non-coil segment;

delivering the stent to a desired location in the bodily vessel, deploying the coil segment and either allowing the non-coil segment to self-expand or balloon expanding the non-coil segment.

19. The method of claim 18 wherein the coil segment is deployed across an aneurysm.

20. A method of manufacturing a stent comprising the steps of:

providing a coil segment and a non-coil segment;

attaching the coil segment to the non-coil segment.

21. The method of claim 20 wherein the coil segment is adhesively bonded to the non-coil segment.

22. The method of claim 20 wherein the coil segment is welded to the non-coil segment.
