<p>PROBLEM TO BE SOLVED: To provide a highly reliable electrode catheter with temperature sensors capable of correctly measuring temperature inside a gullet.SOLUTION: An electrode catheter with temperature sensors includes: a catheter shaft 10 having a tip flexible part 10A; an operation handle 20; an operation wire 30 for flexing the tip flexible part 10A; temperature measurement electrodes 52-55 arranged in the tip flexible part 10A; temperature sensors 62-65 connected to the temperature measurement electrodes 52-55; and temperature sensor lead wires 72-75. The temperature measurement electrodes 52-55 are constituted by conductive columnar bodies 50 to which insulation cylindrical bodies constituting the tip flexible part 10A are connected at both ends. Blind holes 56 extending along a central axis are formed in the conductive columnar bodies 50. The temperature sensors 62-65 are fixed to the conductive columnar bodies 50 inside the blind holes 56 so as to be connected to the temperature measurement electrodes 52-55.</p> |
