Ribbon electrode
First Claim
1. An electrode assembly, comprising:
- a ribbon electrode formed in a shape selected from the group consisting of substantially cylindrical, substantially spiral, and substantially helical conformation having a first surface and a second surface;
a plurality of formations disposed on the second surface of the ribbon electrode, wherein each formation has a third surface substantially not in contact with the second surface of the ribbon electrode thereby forming a channel, and at least one formation is electrically conducting;
a lead wire electrically coupled to the at least one electrically conducting formation through that formations'"'"' channel; and
an insulating material contacting substantially the entire second surface of the ribbon electrode and substantially the entire third surface of each formation;
wherein the insulating material is substantially not in contact with the first surface of the ribbon electrode; and
wherein the electrode assembly is implantable.

Abstract
We disclose an electrode assembly comprising a ribbon electrode having a first surface and a second surface; a plurality of bosses disposed on the second surface of the ribbon electrode, wherein each boss has a third surface substantially not in contact with the second surface of the ribbon electrode and at least one boss is electrically conducting; and an insulator contacting substantially the entire second surface of the ribbon electrode and substantially the entire third surface of each boss; wherein the insulator is substantially not in contact with the first surface of the ribbon electrode. We also disclose an implantable medical device system comprising an implantable medical device for generating an electrical signal; an electrode assembly as described; and a lead wire electrically coupled to both the implantable medical device and at least one electrically conducting boss of the electrode assembly.
