Abstract
A steerable irrigated tip catheter is provided. The catheter includes a catheter body, a control handle at the proximal end of the catheter body, and a tip section at the distal end of the catheter body. The tip section comprises a segment of flexible tubing with a tip electrode fixedly attached to its distal end. The tip electrode has a fluid passage in fluid communication with a lumen in the tip section. The fluid passage comprises at least one transverse passage or is formed by interconnecting pores of the tip electrode. An infusion tube extends through the catheter body and tip section and is anchored at its distal end in the proximal end of the fluid passage in the tip electrode. In use, fluid can flow through the infusion tube, into the fluid passage in the tip electrode and through the tip electrode to the outer surface of the tip electrode.
