摘要：

Tissue ablation is carried out using insertion tube having at least one ablation electrode, a first temperature sensor disposed on the distal portion sufficiently proximate the ablation electrode to detect heat generated during the ablation procedure, a second temperature sensor disposed on the distal portion sufficiently distant from the ablation electrode to be unable to detect the heat, and electronic logic circuitry linked to the first temperature sensor and the second temperature sensor and programmed to compute a temperature differential between respective temperatures sensed by the first temperature sensor and the second temperature sensor when conveying the electromagnetic energy. Satisfactory contact status between the ablation electrode and the target tissue is indicated when the temperature differential exceeds a predetermined threshold.
