First Claim
Patent Images
1. An intravascular lead adapted to be deployed to a stimulation site within a vessel adjacent a nerve to be stimulated, the lead comprising:
- a lead body including a distal portion and a first and a second conductor in electrical communication with a pulse generator;
at least a first electrode coupled to the distal portion and in electrical communication with the first conductor, the first electrode adapted to deliver an electrical pulse across a vessel wall, wherein the first electrode is a cathode including an unmasked electrode portion and a masked electrode portion, the unmasked electrode portion comprising a first electrically active surface including one or more surface features adapted to focus current, and wherein the first electrode is disposed on the distal portion such that the unmasked portion can be directed towards the nerve to be stimulated; and
at least a second electrode coupled to the distal portion and in electrical communication with the second conductor, the second electrode adapted to deliver an electrical pulse across a vessel wall, wherein the second electrode is an anode including a second electrically active surface equal to or greater than the electrically active surface of the first electrode, and wherein the second electrode is also disposed on the distal portion of the lead body such that the electrically active surface can be directed towards the nerve to be stimulated.

Abstract
An intravascular lead adapted to be deployed to a stimulation site within a vessel adjacent a nerve to be stimulated includes at least a first electrode adapted to deliver an electrical pulse across a vessel wall. The first electrode includes an electrically active surface having one or more surface features adapted to focus current. The first electrode is disposed on the distal portion that the electrically active surface can be directed towards the nerve to be stimulated.
