Implantable electrophysiology lead body
View Patent ↗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.
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;
c) a cover, said cover consisting essentially of fluoropolymer, wherein said cover surrounds said longitudinal elements; and
d) at least one lumen disposed within said cover, said lumen comprising a laminate including a first layer of non-porous ePTFE and a second layer of porous ePTFE.
2. The electrophysiology lead body of claim 1 , in which said cover comprises non-porous ePTFE.
3. The electrophysiology lead body of claim 1 in which said cover comprises ePTFE and FEP.
4. The electrophysiology lead body of claim 1 , in which said fluoropolymer is film is wrapped about the outer surface of said conductive material.
5. The electrophysiology lead body of claim 4 , in which said fluoropolymer is film is helically wrapped around said conductive material.
6. The electrophysiology lead body of claim 1 , in which said cover comprises fluoropolymer film wrapped about the outer surface of said longitudinal elements.
7. The electrophysiology lead body of claim 6 , in which the film is helically wrapped about the outer surface of said longitudinal elements.
8. The electrophysiology lead body of claim 1 further comprising at least one additional layer of porous ePTFE.
9. The electrophysiology lead body of claim 1 in which the laminate comprises a first layer of porous ePTFE surrounded by a second layer of non-porous ePTFE.
