Abstract:
A steerable irrigated tip catheter comprising:a catheter body having an outer wall, proximal and distal ends, and a single central lumen extending therethrough;a control handle at the proximal end of the catheter body;a tip section comprising a segment of flexible tubing having proximal and distal ends and at least one lumen therethrough, the proximal end of the tip section being fixedly attached to the distal end of the catheter body;a tip electrode fixedly attached to the distal end of the tubing of the tip section, the tip electrode having at least one fluid passage in fluid communication with a lumen in the tip section;a first infusion tube segment having proximal and distal ends, the first infusion tube segment extending through the central lumen in the catheter body with its distal end being mounted in the proximal end of a lumen in the tip section;a second infusion tube segment having a proximal end mounted in the distal end of the lumen in the tip section in which the first infusion tube segment is mounted and a distal end mounted in the fluid passage in the tip electrode; andmeans for deflecting the tip section by manipulation of the control handle.
