Multi-electrode assembly for an implantable medical device
First Claim
1. A method for forming a helical electrode assembly for carrying a signal associated with an implantable medical device, comprising:
- forming a first layer on a generally flat substrate;
forming a first conducting structure as a second layer upon said first layer, said second layer comprising a first electrode and a first conductive strip operatively coupled to said first electrode;
forming a third, non-conductive layer above said first and second layers;
forming a second conducting structure as a fourth layer upon said third layer, said fourth layer comprising a second electrode and a second conductive strip operatively coupled to said second electrode; and
forming at least a portion of said generally flat substrate and the first, second, third and fourth layers into a helical structure,wherein forming said third layer comprises forming the third layer at an offset position on the second layer such that the third layer does not overlap the region in which the first electrode resides, such that a stair step of layers that contain electrodes and conductive strips is generated.

Abstract
A method, system, and apparatus are provided for an electrode assembly comprising a plurality of electrodes for use with an implantable medical device for conducting an electrical signal between the implantable medical device and a target tissue. The electrode assembly includes a helical member and first and second electrodes formed upon the helical member. The first and second electrodes are adapted to deliver the electrical signal. The electrode assembly also includes a first conductive element formed upon the helical member and operatively coupled to the first electrode. The electrode assembly also includes a second conductive element formed upon the helical member and operatively coupled to the second electrode.
