Abstract
A porous tip electrode and a catheter having the same are provided. The catheter generally comprises a catheter body, tip section and control handle. A porous tip electrode, manufactured by injection molding, is mounted at the distal end of the tip section and comprises a main electrode body and a stem. The catheter further comprises a first irrigation tube segment extending through the catheter body and into the proximal end of the tip section, and a second irrigation tube segment extending from the stem of the tip electrode into the distal end of the tip section. Means for energizing saline or other fluid that passes to the tip electrode can include an inner conductive sleeve in the second irrigation tube segment or a conductive material on the stem of the tip electrode. The energized saline ablates lesions in heart tissue.
