Ablation catheter with balloon |
摘要 |
The present invention aims to provide a balloon ablation catheter that achieves reduction in the diameter of the balloon upon balloon contraction and increased reliability of the thermocouple temperature sensor, which balloon ablation 5 catheter is less likely to be influenced by the heating liquid discharged into the balloon and able to control the balloon surface temperature with high accuracy. The present invention provides a balloon ablation catheter comprising: a shaft wherein a lumen is formed; a balloon wherein the lumen communicates with the inside thereof; and a high-frequency-current-applying electrode formed by coiling a 10 high-frequency-power-supplying lead wire around the shaft while sandwiching a temperature sensor lead wire between the high-frequency-power-supplying lead wire and the shaft such that the temperature sensor lead wire is fixed along the longitudinal direction of the shaft; wherein a thermocouple thermosensor is formed at the point where the high-frequency-power-supplying lead wire and the temperature 15 sensor lead wire constituting the high-frequency-current-applying electrode contact with each other for the first time as seen from the posterior end side in the longitudinal direction.
