Abstract

Elongated conductors are provided. Aspects of the elongated conductors include: an elongated structure having a proximal region and a distal region, where the elongated conductor includes two or more insulated conducting members that are in fixed relative position along at least a portion of the elongated structure and extend from the proximal region to the distal region. A pattern of insulation openings among the insulated conducting members is present at one or both of the proximal and distal regions. Aspects of the invention further include methods of making the elongated conductors, as well as devices that include the elongated conductors.

First claim

What is claimed is:

1. An elongated conductor comprising:
an elongated structure having a proximal region and a distal region and comprising two or more insulated conducting members that are in fixed relative position along at least a portion of the elongated structure and extend from the proximal region to the distal region, wherein the insulated conducting members are configured to define a lumen along at least a portion of the elongated structure; and
a pattern of insulation openings among the insulated conducting members at one or both of the proximal and distal regions.

2. The elongated conductor according to claim 1 , wherein the elongated structure comprises a first pattern of insulation openings among the insulated conducting members at the proximal region and a second pattern of insulation openings among the insulated conducting members at the distal region.

3. The elongated conductor according to claim 1 , wherein the elongated conductor comprises a transversely aligned pattern of insulation openings.

4. The elongated conductor according to claim 1 , wherein the elongated conductor comprises an axially aligned pattern of insulation openings.

5. The elongated conductor according to claim 1 , wherein the elongated conductor comprises both a transversely aligned pattern of insulation openings and an axially aligned pattern of insulation openings.

6. The elongated conductor according to claim 1 , wherein the structure comprises from 2 to 500 insulated conducting members.

7. The elongated conductor according to claim 1 , wherein at least a portion of the elongated conductor is cylindrical.

8. The elongated conductor according to claim 1 , wherein the insulated conducting members assume a braided configuration along at least a portion of the elongated structure.

9. The elongated conductor according to claim 1 , wherein the elongated conductor controlled impedance.

10. The elongated conductor according to claim 1 , wherein the lumen has a diameter ranging from 0.025 to 20.0 mm.

11. The elongated conductor according to claim 1 , wherein elongated conductor comprises an insulated conducting member packing density ranging from 30 to 90%.

12. The elongated conductor according to claim 1 , wherein elongated conductor comprises an insulated conducting member pitch ranging from 6 to 250 μm.

13. The elongated conductor according to claim 1 , wherein the insulated conducting members are not in fixed relative position along at least a portion of the elongated structure.

14. The elongated conductor according to claim 1 , wherein the two or more insulated conductors comprise conductors of differing diameter.

15. The elongated conductor according to claim 1 , wherein the elongated conductor comprises a central insulated conductor surrounded by a plurality of peripheral insulated conductors.

16. The elongated conductor according to claim 1 , wherein the insulated conducting members are present in a sheath.

17. The elongated conductor according to claim 1 , wherein the elongated conductor comprises an electrical shield component.

18. The elongated conductor according to claim 1 , wherein the elongated conductor is dimensioned to be positioned in mammalian vasculature.

19. The elongated conductor according to claim 1 , wherein the insulated conductors of at least one of the proximal and distal regions assume a split configuration.
