Catheter electrode that can simultaneously emit electrical energy and facilitate visualization by magnetic resonance imaging
First Claim
1. An electrode assembly for use on a medical device comprising:
- a main body of electrically conductive material extending along an axis and having a proximal end and a distal end, said body configured for connection to a first end of a first electrical conductor and said body being configured to emit electrical energy when a second end of the first electrical conductor is coupled to an energy source;
said body having a groove disposed at least in part over an outermost surface of said body;
a magnetic resonance imaging (MRI) tracking coil disposed in said groove, said MRI tracking coil comprising electrically insulated wire.

Abstract
An electrode for use on a medical device is disclosed. The electrode may have a main body of electrically conductive material extending along an axis and having a proximal end and a distal end. The body may be configured to emit electrical energy in accordance with a predefined diagnostic or therapeutic function. The body may have a groove disposed over an outermost surface of the body. The electrode may also include a magnetic resonance imaging (MRI) tracking coil disposed in said groove. The MRI tracking coil may comprise electrically insulated wire, for example. A catheter including an electrode, as well as a method for determining the location of an electrode, are also disclosed.
