Abstract
A catheter for ablating tissue comprises a catheter body, a tip section, a branding iron assembly and an infusion tube. The catheter body has an outer wall, proximal and distal ends, and at least one lumen extending therethrough. The tip section comprises a segment of flexible tubing having proximal and distal ends and at least one lumen therethrough. The proximal end of the tip section is fixedly attached to the distal end of the catheter body. The branding iron assembly has proximal and distal ends and is fixedly attached at its proximal end to the distal end of the tubing of the tip section. The branding iron assembly is bent relative to the tubing and comprises a non-retractable tubular electrode formed of a material having shape-memory. The tubular electrode has proximal and distal ends and at least one irrigation port through which fluid can pass from the inside to the outside of the electrode. The infusion tube extends through a lumen in the tip section, with its distal end in fluid communication with the proximal end of the tubular electrode.
