Intravascular Electronics Carrier Electrode for a Transvascular Tissue Stimulation System
First Claim
1. An electrode assembly for implantation to stimulate tissue inside an animal, said electrode assembly comprising:
- an electrode carrier of a mesh material adapted for contacting the tissue; and
a first electrode lead having a first conductor and electrical insulation around the first conductor, wherein a first portion of the first electrode lead is woven through the mesh of the electrode carrier and a first section of the first conductor in that first portion is devoid of the electrical insulation.

Abstract
An intravascular mesh type electrode carrier eliminates material and mechanical transitions between an electrical lead and an electrode by interweaving the conductor of the lead into the carrier mesh. The mesh material of the electrode carrier can be electrically conductive so that the entire carrier functions as the electrode. Alternatively, the mesh material may either be non-conductive or have an outer non-conductive coating, in which cases only the exposed section of the first conductor acts as an electrode. With a non-conductive mesh material, a second electrode lead can be woven through the mesh of the electrode carrier to provide a second electrode.
