Abstract
An irrigated split tip electrode catheter is provided having a composite tip electrode comprising multiple electrode elements adjacent to each other. A central irrigation channel extends into the composite tip electrode which branches into transverse irrigation channels in each electrode element. An infusion tube extends from a Luer hub at the proximal end of the catheter through the catheter body and into the central irrigation channel of the composite tip electrode. A temperature sensor preferably a thermocouple may be provided for each electrode element. In use, a cooling fluid is passed into and through the infusion tube and through each of the electrode elements to cool the electrode elements and the interface between the electrode elements and the myocardium or blood so as to prevent the formation of coagulum.
