Abstract

The invention is an electrophysiology lead body comprising two or more longitudinal elements, each having an outer surface, the longitudinal elements comprising electrical insulation material, the electrical insulation material consisting essentially of fluoropolymer; at least one conductor disposed within at least one of the longitudinal elements; and a cover consisting essentially of fluoropolymer, wherein the cover surrounds the longitudinal elements.

Claims (18)

1. An electrophysiology lead body comprising:

a) two or more longitudinal elements, each having an outer surface, said longitudinal elements comprising electrical insulation material, said insulation material consisting essentially of fluoropolymer;

b) at least one conductor disposed within at least one of said longitudinal elements; and

c) a cover, said cover comprising a composite of ePTFE having a polymeric structure defining voids within a polymer matrix and a filler included within said voids and said polymer matrix, wherein said cover surrounds said longitudinal elements.

2. The electrophysiology lead body of claim 1 , in which the filler comprises an elastomer.

3. The electrophysiology lead body of claim 2 in which the elastomer comprises silicone.

4. The electrophysiology lead body of claim 2 in which the elastomer comprises polyurethane.

5. The electrophysiology lead body of claim 1 , in which the filler comprises a particulate.

6. The electrophysiology lead body of claim 1 , in which the filler comprises a fiber.

7. The electrophysiology lead body of claim 1 , in which the filler is conductive.

8. The electrophysiology lead body of claim 7 , in which the filler is carbon.

9. The electrophysiology lead body of claim 7 , in which the filler is metal.

10. The electrophysiology lead body of claim 7 , in which the filler is metalloid.

11. The electrophysiology lead body of claim 1 , in which the filler is an antimicrobial.

12. The electrophysiology lead body of claim 1 , in which the filler is an antibacterial agent.

13. The electrophysiology lead body of claim 1 , in which the filler is an anti-inflammatory agent.

14. The electrophysiology lead body of claim 1 , in which the filler is a radiopaque agent.

15. The electrophysiology lead body of claim 1 , in which the filler is another fluoropolymer.
