Abstract

Medical devices with radiopaque markers, and related systems and methods are disclosed.

Claims

1. A medical device, comprising:

an elongated body of the medical device, the elongated body having a groove; and

a radiopaque material in the groove.

2. The medical device of claim 1, wherein the elongated body is tube-shaped.

3. The medical device of claim 1, wherein the medical device is an embolic coil.

4. The medical device of claim 1, wherein the medical device is a catheter.

5. The medical device of claim 1, wherein the radiopaque material forms a portion of an outer surface of the medical device.

6. The medical device of claim 5, wherein the difference between a maximum outer diameter of the device along a length of the groove and a maximum outer diameter of the device adjacent to the groove is at most 10% of a maximum thickness of the elongated body.

7. The medical device of claim 1, wherein the groove has a width of at least 0.040 mm.

8. The medical device of claim 1, wherein the groove has a depth of at least 0.1 mm.

9. The medical device of claim 1, wherein the elongated body comprises a polymer.

10. The medical device of claim 1, wherein the elongated body comprises a metal-containing material.

11. The medical device of claim 1, wherein the elongated body comprises a shape memory alloy.

12. The medical device of claim 1, wherein the elongated body comprises nitinol.

13. The medical device of claim 1, wherein the elongated body has a plurality of grooves.

14. The medical device of claim 13, wherein the plurality of grooves form a hatched pattern.

15. The medical device of claim 1, further comprising a coating supported by the elongated body and the radiopaque material.

16. The medical device of claim 1, wherein the radiopaque material is selected from the group consisting of bismuth-containing materials, metals and alloys.

17. The medical device of claim 1, wherein the elongated body has a groove in its inner surface and a groove in its outer surface.

18. A medical device, comprising:

an elongated body of the medical device, the elongated body having a groove; and

a material in the groove,

wherein the difference between a maximum outer diameter of the device along a length of the groove and a maximum outer diameter of the device adjacent to the groove is at most 10% of a maximum thickness of the elongated body.

19. A medical device, comprising:

an elongated body of the medical device; and

a coating comprising a radiopaque material,

wherein the coating is supported by the elongated body, and the coating has a groove.

20. The medical device of claim 19, wherein the groove extends into the elongated body.

21. The medical device of claim 19, wherein the elongated body comprises a polymer.

22. The medical device of claim 19, wherein the elongated body comprises a metal-containing material.

23. The medical device of claim 22, wherein the radiopaque material is selected from the group consisting of bismuth-containing materials, metals and alloys.

24. The medical device of claim 19, wherein the radiopaque material is selected from the group consisting of bismuth-containing materials, metals and alloys.

25. A method of making a medical device, the method comprising:

providing an elongated body of the medical device;

determining a desired distance between radiopaque markers to be associated with the elongated body; and

associating the radiopaque markers with the elongated body to form the medical device, the radiopaque markers being spaced a distance that is within six mils of the desired distance.

26. The method of claim 25, further comprising:

forming grooves in the elongated body; and

disposing a respective radiopaque marker in each groove.

27. A method of making a medical device, the method comprising:

disposing a radiopaque material on an elongated body of the medical device; and

forming a groove in the radiopaque material.

28. The method of claim 27, further comprising forming a groove in the elongated body.

29. The method of claim 27, wherein the radiopaque material is selected from the group consisting of bismuth-containing materials, metals and alloys.

30. The method claim 27, wherein the elongated body comprises a metal-containing material.
