Medical lead with segmented electrode
First Claim
1. A medical lead comprising:
- a conductor assembly comprising at least a first conductor;
a first segmented electrode assembly defining a hole wherein the conductor assembly passes through the hole, and wherein the first segmented electrode assembly comprises;
(i) at least a first conductive segment electrically coupled to the first conductor, the first conductive segment comprisinga first inner surface facing inward toward the conductor assembly,a first outer surface facing tissue upon implantation, anda first passageway defining an encapsulated space between the first inner surface and the first outer surface,a first longitudinal edge extending from the first inner surface to the first outer surface and defining an inlet into the first passageway; and
(ii) a first gap adjacent the first longitudinal edge; and
an insulating material that extends through the first passageway and into the first gap adjacent the first conductive segment.

Abstract
A medical lead having a conductor assembly and a segmented electrode assembly. The segmented electrode assembly includes a conductive segment electrically coupled to a conductor of the conductor assembly. A passageway is positioned between an inner surface and outer surface of the conductive segment. An electrically insulating material extends through the first passageway and into a gap adjacent the conductive segment. A segmented electrode assembly is also provided. The segmented electrode assembly includes a conductive segment having a passageway between an inner surface and outer surface of the conductive segment. An electrically insulating material extends through the passageway and into a gap adjacent the conductive segment.
