ABSTRACT:
The present invention pertains to multiple piece irrigated ablation electrode assemblies wherein the irrigation channels are insulated or separated from at least one temperature sensing mechanism within the distal portion of the electrode assembly. The present invention further pertains to methods for improved assembly and accurate measurement and control of the electrode temperatures while effectively irrigating the device and target areas.
