The present invention relates generally to catheters, and more particularly to a catheter with an improved electrode structure and a method of fabricating the catheter electrodes.
BACKGROUND OF THE INVENTIONCatheters are sometimes provided with electrodes for selectively stimulating and/or sensing electrical activity in body tissue, such as the heart. For example, a catheter may be inserted into the cardiovascular system of the patient, through the superior vena cava (SVC), and into the heart so as to achieve placement of an electrode or electrodes in desired position(s) within the heart or adjacent a chamber of the heart to evoke a response of tissue to an electrical signal applied to the electrodes. The catheter is generally a hollow tube extruded from a resilient polymeric material, such as a silicone or polyurethane rubber, with one or more passages or lumens extending longitudi...
