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. A method of making an elongated conductor, the method comprising:
producing a pattern of insulation openings among two or more insulated conducting members comprised of wires; and
aligning the patterned insulating conducting members in an elongated configuration having a proximal region and a distal region so as to form a pattern between the insulation openings of the patterned insulating conducting members, wherein the method comprises producing the pattern of insulation openings among the insulated conducting members at one or both of the proximal and distal regions.

2. The method according to claim 1 , wherein the method comprises producing 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 method according to claim 1 , wherein pattern of insulation openings is transversely aligned.

4. The method according to claim 1 , wherein the pattern of insulation openings is axially aligned.

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

6. The method according to claim 1 , wherein the method comprises inserting the aligned insulating conductors into a first sheath.

7. The method according to claim 6 , wherein the method further comprises inserting a second sheath into the first sheath between the first sheath and the insulated conducting members.

8. The method according to claim 7 , wherein the method comprises separating the first sheath from the second sheath and insulating conducting members.

9. The method according to claim 6 , wherein at least one of the sheaths comprises a conductive material.

10. The method according to claim 6 , wherein at least one of the sheaths comprises an insulating material.

11. The method according to claim 1 , wherein the method comprises stably associating at least one of the proximal and distal regions with a substrate.

12. The method according to claim 1 , wherein the insulated conductors comprise a conductive core present in an inner insulating coating and an outer coating.

13. The method according to claim 12 , wherein the conductive core comprises an electrically conductive material.

14. The method according to claim 12 , wherein the outer coating comprises a thermoplastic material.

15. The method according to claim 14 , wherein the method comprises heating the thermoplastic material in a manner sufficient to fix the relative position of the insulted conductors.

16. The method according to claim 12 , wherein the inner insulating coating comprises a thermally stable material.

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

18. The method according to claim 1 , wherein the elongated conductor has a length ranging from 5 to 4,000 mm.

19. The method according to claim 1 , wherein the elongated conductor has an outer diameter ranging from 75 μm to 5 mm.

20. The method according to claim 1 , wherein the method is a continuous process.
