Techniques for detecting coagulum formation on an ablation electrode make use of an ablation electrode that is connected to a radio-frequency (RF) generator capable of applying a small amount of RF energy that is not cell destructive. The temperature at the ablation electrode can be precisely measured using a thermosensor incorporated within the ablation electrode. Before and after actual ablation, a low, non-cell destructing (non-ablating) amount of RF energy is generated at the ablation electrode. If no coagulum has formed during actual ablation, the temperature increase during this test application will be similar before and after the ablation attempt. If coagulum has formed during the actual ablation, however, the temperature increase during the test application after ablation will be significantly higher.
