Abstract:
An irrigated split tip electrode catheter, comprising:an elongated catheter body having proximal and distal ends and at least one lumen extending therethrough;a catheter tip section extending from the distal end of the catheter body, the catheter tip section comprising a:flexible tubing having proximal and distal ends and at least one lumen therethrough;a split-tip electrode comprising a tip electrode assembly including at least two adjacent, electrically isolated electrode members fixedly attached at the distal end of the tip section and an irrigation channel through at least one electrode member; andmeans for fixedly connecting the split-tip electrode to the distal end of the flexible tubing;an electrode lead wire electrically connected to each electrode member of the tip electrode assembly, each such electrode lead wire extending through a lumen in the flexible tubing and catheter body to the proximal end of the catheter;an infusion tube which extends through the catheter body and tip section that is in communication with the irrigation channel of the at least one electrode member and means at the proximal end of the infusion tube for introducing a fluid into and through the infusion tube and the irrigation channel of the at least one electrode member; andmeans for controllably deflecting the tip section.
